7ec90fc9de FROMGIT: scsi: ufs: core: scsi_get_lba() error fix 
When ufs initializes without scmd->device->sector_size set, scsi_get_lba()
will get a wrong shift number and trigger an ubsan error.  The shift
exponent 4294967286 is too large for the 64-bit type 'sector_t' (aka
'unsigned long long').

Call scsi_get_lba() only when opcode is READ_10/WRITE_10/UNMAP.

6c55ca2cae ANDROID: Add flag to indicate compiling against ACK 
Add a flag: __ANDROID_COMMON_KERNEL__ which out-of-tree vendor drivers
can use to check if they are compiling against an Android Common Kernel.
These out-of-tree vendor drivers can use this flag +
LINUX_KERNEL_VERSION to determine if a feature has been backported.

There are two tracepoints in usb_gadget_connect() and
usb_gadget_disconnect(). This patch will export the tracepoints so that
vendor modules can use them.

def3ff8c55 ANDROID: sched/rt: Only enable RT sync for SMP targets 
The rt sync wakeup support has a condition which relies on a field that
exists only when CONFIG_SMP is defined, causing a compilation issue.
Since sync wakeup has no real meaning on a non-SMP system, we can just
drop the CONFIG_RT_GROUP_SCHED part of the #ifdef.

a7133dd750 ANDROID: sched/rt: Add support for rt sync wakeups 
Some rt tasks undergo sync wakeup. Currently, these tasks will be placed
on other, often sleeping or otherwise idle CPUs, which can lead to
unnecessary power hits.

9f7014a6d2 ANDROID: irq: manage: Export irq_do_set_affinity symbol 
Vendor kernel modules may implement irq balancers, which could
take irq desc lock of an irq and then based on current affinity
mask or affinity hint, reconfigure the affinity of that irq.
For example : For an irq, for which affinity is broken i.e. all
the cpus in its affinity mask have gone offline. For such irqs,
we might want to reset the affinity, when the original set of
affined cpus, come back online. desc->affinity_hint can be used
for figuring out the original affinity. So, the sequence for doing
this becomes:

desc = irq_to_desc(i);
raw_spin_lock(&desc->lock);
affinity = desc->affinity_hint;
raw_spin_unlock(&desc->lock);
irq_set_affinity_hint(i, affinity);

Here, we need to release the desc lock before calling the exported
api irq_set_affinity_hint(). This creates a window where, after
unlocking desc lock and before calling irq_set_affinity_hint(),
where this setting can race with other irq_set_affinity_hint()
callers. So, export irq_do_set_affinity() symbol to provide an
api, which can be called with desc lock held.

Some devices may return invalid or zeroed data during an UIC error
condition. In addition, reading these SFRs will clear them. This means the
subsequent error handling will not be able to see them and therefore no
error handling will be scheduled.

Skip reading these SFRs in ufshcd_dump_regs().

520d88005f ANDROID: KVM: arm64: s2mpu: Allow reading MPTC entries 
The state of the S2MPU does not need to be kept secret from the host as
it merely reflects the permissions that the host has and knows about.
To make debugging DMA issues easier, allow the host to query entries
from the MPTC cache. This involves writing the set and way IDs of the
query to the READ_MPTC register and then reading the MPTC entry
information from READ_MPTC_TAG_PPN/TAG_OTHERS/DATA. Modify the S2MPU
DABT handler to allow this register access pattern.

fdfed49bf7 ANDROID: KVM: arm64: s2mpu: Allow L1ENTRY_* r/o access 
Allow read-only access to L1ENTRY_ATTR and L1ENTRY_L2TABLE S2MPU
registers. This allows the host to dump the register state for debugging
purposes. It is safe because the state of the S2MPU is known to the host
anyway.

71e7a059a0 ANDROID: Suppress build.sh deprecation warnings. 
build.sh will continued to be supported in android13-*
branches. To avoid confusion, suppress the deprecation
warnings when executing build.sh on android13-*.

This change also avoids the time delay for inferring
the equivalent Bazel command.

It is still encouraged to migrate build.sh to Bazel.

Test: manually execute build.sh, no deprecation warnings

3d18c9ea72 FROMLIST: mm: multi-gen LRU: debugfs interface 
Add /sys/kernel/debug/lru_gen for working set estimation and proactive
reclaim. These features are required to optimize job scheduling (bin
packing) in data centers [1][2].

Compared with the page table-based approach and the PFN-based
approach, e.g., mm/damon/[vp]addr.c, this lruvec-based approach has
the following advantages:
1. It offers better choices because it is aware of memcgs, NUMA nodes,
   shared mappings and unmapped page cache.
2. It is more scalable because it is O(nr_hot_pages), whereas the
   PFN-based approach is O(nr_total_pages).

Add /sys/kernel/debug/lru_gen_full for debugging.

e8507816d1 FROMLIST: mm: multi-gen LRU: thrashing prevention 
Add /sys/kernel/mm/lru_gen/min_ttl_ms for thrashing prevention, as
requested by many desktop users [1].

When set to value N, it prevents the working set of N milliseconds
from getting evicted. The OOM killer is triggered if this working set
cannot be kept in memory. Based on the average human detectable lag
(~100ms), N=1000 usually eliminates intolerable lags due to thrashing.
Larger values like N=3000 make lags less noticeable at the risk of
premature OOM kills.

Compared with the size-based approach, e.g., [2], this time-based
approach has the following advantages:
1. It is easier to configure because it is agnostic to applications
   and memory sizes.
2. It is more reliable because it is directly wired to the OOM killer.

76f7f07cbf FROMLIST: mm: multi-gen LRU: kill switch 
Add /sys/kernel/mm/lru_gen/enabled as a kill switch. Components that
can be disabled include:
  0x0001: the multi-gen LRU core
  0x0002: walking page table, when arch_has_hw_pte_young() returns
          true
  0x0004: clearing the accessed bit in non-leaf PMD entries, when
          CONFIG_ARCH_HAS_NONLEAF_PMD_YOUNG=y
  [yYnN]: apply to all the components above
E.g.,
  echo y >/sys/kernel/mm/lru_gen/enabled
  cat /sys/kernel/mm/lru_gen/enabled
  0x0007
  echo 5 >/sys/kernel/mm/lru_gen/enabled
  cat /sys/kernel/mm/lru_gen/enabled
  0x0005

NB: the page table walks happen on the scale of seconds under heavy
memory pressure, in which case the mmap_lock contention is a lesser
concern, compared with the LRU lock contention and the I/O congestion.
So far the only well-known case of the mmap_lock contention happens on
Android, due to Scudo [1] which allocates several thousand VMAs for
merely a few hundred MBs. The SPF and the Maple Tree also have
provided their own assessments [2][3]. However, if walking page tables
does worsen the mmap_lock contention, the kill switch can be used to
disable it. In this case the multi-gen LRU will suffer a minor
performance degradation, as shown previously.

Clearing the accessed bit in non-leaf PMD entries can also be
disabled, since this behavior was not tested on x86 varieties other
than Intel and AMD.

4d905e91d4 FROMLIST: mm: multi-gen LRU: optimize multiple memcgs 
When multiple memcgs are available, it is possible to make better
choices based on generations and tiers and therefore improve the
overall performance under global memory pressure. This patch adds a
rudimentary optimization to select memcgs that can drop single-use
unmapped clean pages first. Doing so reduces the chance of going into
the aging path or swapping. These two operations can be costly.

A typical example that benefits from this optimization is a server
running mixed types of workloads, e.g., heavy anon workload in one
memcg and heavy buffered I/O workload in the other.

Though this optimization can be applied to both kswapd and direct
reclaim, it is only added to kswapd to keep the patchset manageable.
Later improvements will cover the direct reclaim path.

5280d76d38 FROMLIST: mm: multi-gen LRU: support page table walks 
To further exploit spatial locality, the aging prefers to walk page
tables to search for young PTEs and promote hot pages. A kill switch
will be added in the next patch to disable this behavior. When
disabled, the aging relies on the rmap only.

NB: this behavior has nothing similar with the page table scanning in
the 2.4 kernel [1], which searches page tables for old PTEs, adds cold
pages to swapcache and unmaps them.

To avoid confusion, the term "iteration" specifically means the
traversal of an entire mm_struct list; the term "walk" will be applied
to page tables and the rmap, as usual.

An mm_struct list is maintained for each memcg, and an mm_struct
follows its owner task to the new memcg when this task is migrated.
Given an lruvec, the aging iterates lruvec_memcg()->mm_list and calls
walk_page_range() with each mm_struct on this list to promote hot
pages before it increments max_seq.

When multiple page table walkers iterate the same list, each of them
gets a unique mm_struct; therefore they can run concurrently. Page
table walkers ignore any misplaced pages, e.g., if an mm_struct was
migrated, pages it left in the previous memcg will not be promoted
when its current memcg is under reclaim. Similarly, page table walkers
will not promote pages from nodes other than the one under reclaim.

This patch uses the following optimizations when walking page tables:
1. It tracks the usage of mm_struct's between context switches so that
   page table walkers can skip processes that have been sleeping since
   the last iteration.
2. It uses generational Bloom filters to record populated branches so
   that page table walkers can reduce their search space based on the
   query results, e.g., to skip page tables containing mostly holes or
   misplaced pages.
3. It takes advantage of the accessed bit in non-leaf PMD entries when
   CONFIG_ARCH_HAS_NONLEAF_PMD_YOUNG=y.
4. It does not zigzag between a PGD table and the same PMD table
   spanning multiple VMAs. IOW, it finishes all the VMAs within the
   range of the same PMD table before it returns to a PGD table. This
   improves the cache performance for workloads that have large
   numbers of tiny VMAs [2], especially when CONFIG_PGTABLE_LEVELS=5.

afd94c9ef9 FROMLIST: mm: multi-gen LRU: exploit locality in rmap 
Searching the rmap for PTEs mapping each page on an LRU list (to test
and clear the accessed bit) can be expensive because pages from
different VMAs (PA space) are not cache friendly to the rmap (VA
space). For workloads mostly using mapped pages, the rmap has a high
CPU cost in the reclaim path.

This patch exploits spatial locality to reduce the trips into the
rmap. When shrink_page_list() walks the rmap and finds a young PTE, a
new function lru_gen_look_around() scans at most BITS_PER_LONG-1
adjacent PTEs. On finding another young PTE, it clears the accessed
bit and updates the gen counter of the page mapped by this PTE to
(max_seq%MAX_NR_GENS)+1.

a1537a68c5 FROMLIST: mm: multi-gen LRU: minimal implementation 
To avoid confusion, the terms "promotion" and "demotion" will be
applied to the multi-gen LRU, as a new convention; the terms
"activation" and "deactivation" will be applied to the active/inactive
LRU, as usual.

The aging produces young generations. Given an lruvec, it increments
max_seq when max_seq-min_seq+1 approaches MIN_NR_GENS. The aging
promotes hot pages to the youngest generation when it finds them
accessed through page tables; the demotion of cold pages happens
consequently when it increments max_seq. The aging has the complexity
O(nr_hot_pages), since it is only interested in hot pages. Promotion
in the aging path does not require any LRU list operations, only the
updates of the gen counter and lrugen->nr_pages[]; demotion, unless as
the result of the increment of max_seq, requires LRU list operations,
e.g., lru_deactivate_fn().

The eviction consumes old generations. Given an lruvec, it increments
min_seq when the lists indexed by min_seq%MAX_NR_GENS become empty. A
feedback loop modeled after the PID controller monitors refaults over
anon and file types and decides which type to evict when both types
are available from the same generation.

Each generation is divided into multiple tiers. Tiers represent
different ranges of numbers of accesses through file descriptors. A
page accessed N times through file descriptors is in tier
order_base_2(N). Tiers do not have dedicated lrugen->lists[], only
bits in page->flags. In contrast to moving across generations, which
requires the LRU lock, moving across tiers only involves operations on
page->flags. The feedback loop also monitors refaults over all tiers
and decides when to protect pages in which tiers (N>1), using the
first tier (N=0,1) as a baseline. The first tier contains single-use
unmapped clean pages, which are most likely the best choices. The
eviction moves a page to the next generation, i.e., min_seq+1, if the
feedback loop decides so. This approach has the following advantages:
1. It removes the cost of activation in the buffered access path by
   inferring whether pages accessed multiple times through file
   descriptors are statistically hot and thus worth protecting in the
   eviction path.
2. It takes pages accessed through page tables into account and avoids
   overprotecting pages accessed multiple times through file
   descriptors. (Pages accessed through page tables are in the first
   tier, since N=0.)
3. More tiers provide better protection for pages accessed more than
   twice through file descriptors, when under heavy buffered I/O
   workloads.

f88ed5a3d3 FROMLIST: mm: multi-gen LRU: groundwork 
Evictable pages are divided into multiple generations for each lruvec.
The youngest generation number is stored in lrugen->max_seq for both
anon and file types as they are aged on an equal footing. The oldest
generation numbers are stored in lrugen->min_seq[] separately for anon
and file types as clean file pages can be evicted regardless of swap
constraints. These three variables are monotonically increasing.

Generation numbers are truncated into order_base_2(MAX_NR_GENS+1) bits
in order to fit into the gen counter in page->flags. Each truncated
generation number is an index to lrugen->lists[]. The sliding window
technique is used to track at least MIN_NR_GENS and at most
MAX_NR_GENS generations. The gen counter stores a value within [1,
MAX_NR_GENS] while a page is on one of lrugen->lists[]. Otherwise it
stores 0.

There are two conceptually independent procedures: "the aging", which
produces young generations, and "the eviction", which consumes old
generations. They form a closed-loop system, i.e., "the page reclaim".
Both procedures can be invoked from userspace for the purposes of
working set estimation and proactive reclaim. These features are
required to optimize job scheduling (bin packing) in data centers. The
variable size of the sliding window is designed for such use cases
[1][2].

To avoid confusion, the terms "hot" and "cold" will be applied to the
multi-gen LRU, as a new convention; the terms "active" and "inactive"
will be applied to the active/inactive LRU, as usual.

The protection of hot pages and the selection of cold pages are based
on page access channels and patterns. There are two access channels:
one through page tables and the other through file descriptors. The
protection of the former channel is by design stronger because:
1. The uncertainty in determining the access patterns of the former
   channel is higher due to the approximation of the accessed bit.
2. The cost of evicting the former channel is higher due to the TLB
   flushes required and the likelihood of encountering the dirty bit.
3. The penalty of underprotecting the former channel is higher because
   applications usually do not prepare themselves for major page
   faults like they do for blocked I/O. E.g., GUI applications
   commonly use dedicated I/O threads to avoid blocking the rendering
   threads.
There are also two access patterns: one with temporal locality and the
other without. For the reasons listed above, the former channel is
assumed to follow the former pattern unless VM_SEQ_READ or
VM_RAND_READ is present; the latter channel is assumed to follow the
latter pattern unless outlying refaults have been observed [3][4].

The next patch will address the "outlying refaults". Three macros,
i.e., LRU_REFS_WIDTH, LRU_REFS_PGOFF and LRU_REFS_MASK, used later are
added in this patch to make the entire patchset less diffy.

A page is added to the youngest generation on faulting. The aging
needs to check the accessed bit at least twice before handing this
page over to the eviction. The first check takes care of the accessed
bit set on the initial fault; the second check makes sure this page
has not been used since then. This protocol, AKA second chance,
requires a minimum of two generations, hence MIN_NR_GENS.
