In commit d909d381c3 ("io_uring: drop any code related to
SCM_RIGHTS"), the internal struct io_ring_ctx structure was changed.
Due to some symbol leakage, the .stg abi checking wants to track this
structure, but it is safe to change as it is limited to the internal
io_uring code only.
INFO: type 'struct io_ring_ctx' changed
member 'struct { struct io_wq_hash* hash_map; struct user_struct* user; struct mm_struct* mm_account; struct llist_head fallback_llist; struct delayed_work fallback_work; struct work_struct exit_work; struct list_head tctx_list; struct completion ref_comp; u32 iowq_limits[2]; bool iowq_limits_set; }' was added
member 'struct { struct socket* ring_sock; struct io_wq_hash* hash_map; struct user_struct* user; struct mm_struct* mm_account; struct llist_head fallback_llist; struct delayed_work fallback_work; struct work_struct exit_work; struct list_head tctx_list; struct completion ref_comp; u32 iowq_limits[2]; bool iowq_limits_set; }' was removed

In commit d951cf510f ("cpufreq: brcmstb-avs-cpufreq: add check for
cpufreq_cpu_get's return value"), a check is made in a way that causes a
build warning, which in Android systems, breaks the build. Fix this up
by moving the definition of the variable above the check to remove the
warning.

This reverts commit 37d98fb9c3 which is
commit 876673364161da50eed6b472d746ef88242b2368 upstream.
It breaks the build as other previous commits that were reverted for ABI
issues are not in the tree here.

The correct printk format specifier when calculating buffer offsets
should be "%tx" as it is a pointer difference (a.k.a ptrdiff_t). This
fixes some W=1 build warnings reported by the kernel test robot.

The data transfer rate using Google Restore in USB3.2 mode is slower,
only about 140MB/s at 5Gbps.
The bMaxBurst is not set, and num_fifos in
dwc3_gadget_resize_tx_fifosis 1, which results
in only 131btye of dwc3 ram space being allocated to ep.
Modify bMaxBurst to 6.
The 5Gbps rate increases from 140MB/s to 350MB/s.
The 10Gbps rate is increased from 220MB/s to 500MB/s.

In commit 5ae5060e17 ("mmc: mmci: stm32: fix DMA API overlapping

add it to the virtual symbol list so that build target continues to work
properly.

When a Fast Role Swap control message attempt results in a transition
to ERROR_RECOVERY, the TCPC can still queue a TCPM_SOURCING_VBUS event.
If the event is queued but processed after the tcpm_reset_port() call
in the PORT_RESET state, then the following occurs:
1. tcpm_reset_port() calls tcpm_init_vbus() to reset the vbus sourcing and
sinking state
2. tcpm_pd_event_handler() turns VBUS on before the port is in the default
state.
3. The port resolves as a sink. In the SNK_DISCOVERY state,
tcpm_set_charge() cannot set vbus to charge.
Clear pd events within PORT_RESET to get rid of non-applicable events.

Before sending Enter Mode for an Alt Mode, there is a gap between Discover
Modes and the Alt Mode driver queueing the Enter Mode VDM for the port
partner to send a message to the port.
If this message results in unregistering Alt Modes such as in a DR_SWAP,
then the following deadlock can occur with respect to the DisplayPort Alt
Mode driver:
1. The DR_SWAP state holds port->lock. Unregistering the Alt Mode driver
results in a cancel_work_sync() that waits for the current dp_altmode_work
to finish.
2. dp_altmode_work makes a call to tcpm_altmode_enter. The deadlock occurs
because tcpm_queue_vdm_unlock attempts to hold port->lock.
Before attempting to grab the lock, ensure that the port is in a state
vdm_run_state_machine can run in. Alt Mode unregistration will not occur
in these states.

There is an issue in clang's ThinLTO caching (enabled for the kernel via
'--thinlto-cache-dir') with .incbin, which the kernel occasionally uses
to include data within the kernel, such as the .config file for
/proc/config.gz. For example, when changing the .config and rebuilding
vmlinux, the copy of .config in vmlinux does not match the copy of
.config in the build folder:
$ echo 'CONFIG_LTO_NONE=n
CONFIG_LTO_CLANG_THIN=y
CONFIG_IKCONFIG=y
CONFIG_HEADERS_INSTALL=y' >kernel/configs/repro.config
$ make -skj"$(nproc)" ARCH=x86_64 LLVM=1 clean defconfig repro.config vmlinux
...
$ grep CONFIG_HEADERS_INSTALL .config
CONFIG_HEADERS_INSTALL=y
$ scripts/extract-ikconfig vmlinux | grep CONFIG_HEADERS_INSTALL
CONFIG_HEADERS_INSTALL=y
$ scripts/config -d HEADERS_INSTALL
$ make -kj"$(nproc)" ARCH=x86_64 LLVM=1 vmlinux
...
UPD kernel/config_data
GZIP kernel/config_data.gz
CC kernel/configs.o
...
LD vmlinux
...
$ grep CONFIG_HEADERS_INSTALL .config
# CONFIG_HEADERS_INSTALL is not set
$ scripts/extract-ikconfig vmlinux | grep CONFIG_HEADERS_INSTALL
CONFIG_HEADERS_INSTALL=y
Without '--thinlto-cache-dir' or when using full LTO, this issue does
not occur.
Benchmarking incremental builds on a few different machines with and
without the cache shows a 20% increase in incremental build time without
the cache when measured by touching init/main.c and running 'make all'.
ARCH=arm64 defconfig + CONFIG_LTO_CLANG_THIN=y on an arm64 host:
Benchmark 1: With ThinLTO cache
Time (mean ± σ): 56.347 s ± 0.163 s [User: 83.768 s, System: 24.661 s]
Range (min … max): 56.109 s … 56.594 s 10 runs
Benchmark 2: Without ThinLTO cache
Time (mean ± σ): 67.740 s ± 0.479 s [User: 718.458 s, System: 31.797 s]
Range (min … max): 67.059 s … 68.556 s 10 runs
Summary
With ThinLTO cache ran
1.20 ± 0.01 times faster than Without ThinLTO cache
ARCH=x86_64 defconfig + CONFIG_LTO_CLANG_THIN=y on an x86_64 host:
Benchmark 1: With ThinLTO cache
Time (mean ± σ): 85.772 s ± 0.252 s [User: 91.505 s, System: 8.408 s]
Range (min … max): 85.447 s … 86.244 s 10 runs
Benchmark 2: Without ThinLTO cache
Time (mean ± σ): 103.833 s ± 0.288 s [User: 232.058 s, System: 8.569 s]
Range (min … max): 103.286 s … 104.124 s 10 runs
Summary
With ThinLTO cache ran
1.21 ± 0.00 times faster than Without ThinLTO cache
While it is unfortunate to take this performance improvement off the
table, correctness is more important. If/when this is fixed in LLVM, it
can potentially be brought back in a conditional manner. Alternatively,
a developer can just disable LTO if doing incremental compiles quickly
is important, as a full compile cycle can still take over a minute even
with the cache and it is unlikely that LTO will result in functional
differences for a kernel change.

If the kernel is built CONFIG_CFI_CLANG=y, reading smaps
may cause a panic. This is due to a failed CFI check; which
is triggered becuase the signature of the function pointer for
printing smaps padding VMAs does not match exactly with that
for show_smap().
Fix this by casting the function pointer to the expected type
based on whether printing maps or smaps padding.

In some cases a VMA with padding representation may be split, and
therefore the padding flags must be updated accordingly.
There are 3 cases to handle:
Given:
| DDDDPPPP |
where:
- D represents 1 page of data;
- P represents 1 page of padding;
- | represents the boundaries (start/end) of the VMA
1) Split exactly at the padding boundary
| DDDDPPPP | --> | DDDD | PPPP |
- Remove padding flags from the first VMA.
- The second VMA is all padding
2) Split within the padding area
| DDDDPPPP | --> | DDDDPP | PP |
- Subtract the length of the second VMA from the first VMA's
padding.
- The second VMA is all padding, adjust its padding length (flags)
3) Split within the data area
| DDDDPPPP | --> | DD | DDPPPP |
- Remove padding flags from the first VMA.
- The second VMA is has the same padding as from before the split.
To simplify the semantics merging of padding VMAs is not allowed.
If a split produces a VMA that is entirely padding, show_[s]maps()
only outputs the padding VMA entry (as the data entry is of length 0).

Only preform padding advise from the execution context on bionic's
dynamic linker. This ensures that madvise() doesn't have unwanted
side effects.
Also rearrange the order of fail checks in madvise_vma_pad_pages()
in order of ascending cost.

To allow more flexible arrangements while still provide a single kernel
for distros, provide a boot time parameter to enable/disable lazy RCU.
Specify:
rcutree.enable_rcu_lazy=[y|1|n|0]
Which also requires
rcu_nocbs=all
at boot time to enable/disable lazy RCU.
To disable it by default at build time when CONFIG_RCU_LAZY=y, the new
CONFIG_RCU_LAZY_DEFAULT_OFF can be used.

On many systems, a great deal of boot (in userspace) happens after the
kernel thinks the boot has completed. It is difficult to determine if
the system has really booted from the kernel side. Some features like
lazy-RCU can risk slowing down boot time if, say, a callback has been
added that the boot synchronously depends on. Further expedited callbacks
can get unexpedited way earlier than it should be, thus slowing down
boot (as shown in the data below).
For these reasons, this commit adds a config option
'CONFIG_RCU_BOOT_END_DELAY' and a boot parameter rcupdate.boot_end_delay.
Userspace can also make RCU's view of the system as booted, by writing the
time in milliseconds to: /sys/module/rcupdate/parameters/android_rcu_boot_end_delay
Or even just writing a value of 0 to this sysfs node.
However, under no circumstance will the boot be allowed to end earlier
than just before init is launched.
The default value of CONFIG_RCU_BOOT_END_DELAY is chosen as 15s. This
suites ChromeOS and also a PREEMPT_RT system below very well, which need
no config or parameter changes, and just a simple application of this
patch. A system designer can also choose a specific value here to keep
RCU from marking boot completion. As noted earlier, RCU's perspective
of the system as booted will not be marker until at least
android_rcu_boot_end_delay milliseconds have passed or an update is made
via writing a small value (or 0) in milliseconds to:
/sys/module/rcupdate/parameters/android_rcu_boot_end_delay.
One side-effect of this patch is, there is a risk that a real-time workload
launched just after the kernel boots will suffer interruptions due to expedited
RCU, which previous ended just before init was launched. However, to mitigate
such an issue (however unlikely), the user should either tune
CONFIG_RCU_BOOT_END_DELAY to a smaller value than 15 seconds or write a value
of 0 to /sys/module/rcupdate/parameters/android_rcu_boot_end_delay, once userspace
boots, and before launching the real-time workload.
Qiuxu also noted impressive boot-time improvements with earlier version
of patch. An excerpt from the data he shared:
1) Testing environment:
OS : CentOS Stream 8 (non-RT OS)
Kernel : v6.2
Machine : Intel Cascade Lake server (2 sockets, each with 44 logical threads)
Qemu args : -cpu host -enable-kvm, -smp 88,threads=2,sockets=2, …
2) OS boot time definition:
The time from the start of the kernel boot to the shell command line
prompt is shown from the console. [ Different people may have
different OS boot time definitions. ]
3) Measurement method (very rough method):
A timer in the kernel periodically prints the boot time every 100ms.
As soon as the shell command line prompt is shown from the console,
we record the boot time printed by the timer, then the printed boot
time is the OS boot time.
4) Measured OS boot time (in seconds)
a) Measured 10 times w/o this patch:
8.7s, 8.4s, 8.6s, 8.2s, 9.0s, 8.7s, 8.8s, 9.3s, 8.8s, 8.3s
The average OS boot time was: ~8.7s
b) Measure 10 times w/ this patch:
8.5s, 8.2s, 7.6s, 8.2s, 8.7s, 8.2s, 7.8s, 8.2s, 9.3s, 8.4s
The average OS boot time was: ~8.3s.
(CHROMIUM tag rationale: Submitted upstream but got lots of pushback as
it may harm a PREEMPT_RT system -- the concern is VERY theoretical and
this improves things for ChromeOS. Plus we are not a PREEMPT_RT system.
So I am strongly suggesting this mostly simple change for ChromeOS.)
