1c333d1861 mm: fix suspend crash on u200 [1/1]
PD#SWPL-1219

Problem:
When open vmap stack, suspend will fail on U200. If open cpu idle,
resume from idle will fail too.

Solution:
set up vmap stack early before open IRQ. If set up this stack late
than IRQ open, stack will point to a ramdom address

Verify:
u200

76789cadf7 mm: optimize thread stack usage on arm64 [1/1]
PD#SWPL-1219

Problem:
On arm64, thread stack is 16KB for each task. If running task number
is large, this type of memory may over 40MB. It's a large amount on
small memory platform. But most case thread only use less 4KB stack.
It's waste of memory and we need optimize it.

Solution:
1. Pre-allocate a vmalloc address space for task stack;
2. Only map 1st page for stack and handle page fault in EL1
   when stack growth triggered exception;
3. handle stack switch for exception.

Verify:

5623da0656 arm64: ftrace: don't adjust the LR value
[ Upstream commit 6e803e2e6e ]

The core ftrace code requires that when it is handed the PC of an
instrumented function, this PC is the address of the instrumented
instruction. This is necessary so that the core ftrace code can identify
the specific instrumentation site. Since the instrumented function will
be a BL, the address of the instrumented function is LR - 4 at entry to
the ftrace code.

This fixup is applied in the mcount_get_pc and mcount_get_pc0 helpers,
which acquire the PC of the instrumented function.

The mcount_get_lr helper is used to acquire the LR of the instrumented
function, whose value does not require this adjustment, and cannot be
adjusted to anything meaningful. No adjustment of this value is made on
other architectures, including arm. However, arm64 adjusts this value by
4.

This patch brings arm64 in line with other architectures and removes the
adjustment of the LR value.

828316e65c arm64: hibernate: Clean the __hyp_text to PoC after resume
commit f7daa9c8fd upstream.

During resume hibernate restores all physical memory. Any memory
that is accessed with the MMU disabled needs to be cleaned to the
PoC.

KVMs __hyp_text was previously ommitted as it runs with the MMU
enabled, but now that the hyp-stub is located in this section,
we must clean __hyp_text too.

This ensures secondary CPUs that come online after hibernate
has finished resuming, and load KVM via the freshly written
hyp-stub see the correct instructions.

c5edde9899 arm64: hyp-stub: Forbid kprobing of the hyp-stub
commit 8fac5cbdfe upstream.

The hyp-stub is loaded by the kernel's early startup code at EL2
during boot, before KVM takes ownership later. The hyp-stub's
text is part of the regular kernel text, meaning it can be kprobed.

A breakpoint in the hyp-stub causes the CPU to spin in el2_sync_invalid.

Add it to the __hyp_text.

62d1d2b720 arm64: kaslr: ensure randomized quantities are clean also when kaslr is off
commit 8ea2359323 upstream.

Commit 1598ecda7b ("arm64: kaslr: ensure randomized quantities are
clean to the PoC") added cache maintenance to ensure that global
variables set by the kaslr init routine are not wiped clean due to
cache invalidation occurring during the second round of page table
creation.

However, if kaslr_early_init() exits early with no randomization
being applied (either due to the lack of a seed, or because the user
has disabled kaslr explicitly), no cache maintenance is performed,
leading to the same issue we attempted to fix earlier, as far as the
module_alloc_base variable is concerned.

Note that module_alloc_base cannot be initialized statically, because
that would cause it to be subject to a R_AARCH64_RELATIVE relocation,
causing it to be overwritten by the second round of KASLR relocation
processing.

3ec9b77542 arm64: kaslr: ensure randomized quantities are clean to the PoC
commit 1598ecda7b upstream.

kaslr_early_init() is called with the kernel mapped at its
link time offset, and if it returns with a non-zero offset,
the kernel is unmapped and remapped again at the randomized
offset.

During its execution, kaslr_early_init() also randomizes the
base of the module region and of the linear mapping of DRAM,
and sets two variables accordingly. However, since these
variables are assigned with the caches on, they may get lost
during the cache maintenance that occurs when unmapping and
remapping the kernel, so ensure that these values are cleaned
to the PoC.

cd350ae3c8 arm64/kvm: consistently handle host HCR_EL2 flags
[ Backport of upstream commit 4eaed6aa2c ]

In KVM we define the configuration of HCR_EL2 for a VHE HOST in
HCR_HOST_VHE_FLAGS, but we don't have a similar definition for the
non-VHE host flags, and open-code HCR_RW. Further, in head.S we
open-code the flags for VHE and non-VHE configurations.

In future, we're going to want to configure more flags for the host, so
lets add a HCR_HOST_NVHE_FLAGS defintion, and consistently use both
HCR_HOST_VHE_FLAGS and HCR_HOST_NVHE_FLAGS in the kvm code and head.S.

We now use mov_q to generate the HCR_EL2 value, as we use when
configuring other registers in head.S.

Solution:
    there is a risk to fetch the timer lock. when input stop, stop_timer
    will call del_timer, at the same time the function
    "aml_i2s_hrtimer_callback" is waiting for the timer lock,after
    stop_timer release the lock,"aml_i2s_hrtimer_callback" get the
    lock and call mod_timer again, which will set the timer to pending
    status. It will cause the next  "start input" stage,add_timer will
    trigger BUG_ON.Now we put the lock before the active status
    checking then we will not touch the timer.

3. rx error when work in loopback mode at high speed.

Solution:
1. change to disable irq at the irq-handle begining;
change to enable irq after all data pulled.
2. pre-setup of every spi transfer spends most of time on clk_set_rate().

a683009568 arm64: Fix mismatched cache line size detection
commit 4c4a39dd5f upstream.

If there is a mismatch in the I/D min line size, we must
always use the system wide safe value both in applications
and in the kernel, while performing cache operations. However,
we have been checking more bits than just the min line sizes,
which triggers false negatives. We may need to trap the user
accesses in such cases, but not necessarily patch the kernel.

This patch fixes the check to do the right thing as advertised.
A new capability will be added to check mismatches in other
fields and ensure we trap the CTR accesses.

In order to forward the guest's ARCH_WORKAROUND_2 calls to EL3,

Note that since we need to execute branches, this always executes
after the Spectre-v2 mitigation has been applied.

commit 647d0519b5 upstream.

On a system where firmware can dynamically change the state of the
mitigation, the CPU will always come up with the mitigation enabled,

If the user has requested "no mitigation" via a command line option,
let's enforce it by calling into the firmware again to disable it.

Similarily, for a resume from hibernate, the mitigation could have
been disabled by the boot kernel. Let's ensure that it is set
back on in that case.

cab367c1c9 KVM: arm64: Avoid storing the vcpu pointer on the stack
Commit 4464e210de upstream.

We already have the percpu area for the host cpu state, which points to
the VCPU, so there's no need to store the VCPU pointer on the stack on
every context switch.  We can be a little more clever and just use
tpidr_el2 for the percpu offset and load the VCPU pointer from the host
context.

This has the benefit of being able to retrieve the host context even
when our stack is corrupted, and it has a potential performance benefit
because we trade a store plus a load for an mrs and a load on a round
trip to the guest.

This does require us to calculate the percpu offset without including
the offset from the kernel mapping of the percpu array to the linear
mapping of the array (which is what we store in tpidr_el1), because a
PC-relative generated address in EL2 is already giving us the hyp alias
of the linear mapping of a kernel address.  We do this in
__cpu_init_hyp_mode() by using kvm_ksym_ref().

The code that accesses ESR_EL2 was previously using an alternative to
use the _EL1 accessor on VHE systems, but this was actually unnecessary
as the _EL1 accessor aliases the ESR_EL2 register on VHE, and the _EL2
accessor does the same thing on both systems.

3e75f25aad arm64: alternatives: Add dynamic patching feature
Commit dea5e2a4c5 upstream.

We've so far relied on a patching infrastructure that only gave us
a single alternative, without any way to provide a range of potential
replacement instructions. For a single feature, this is an all or
nothing thing.

It would be interesting to have a more flexible grained way of patching
the kernel though, where we could dynamically tune the code that gets
injected.

In order to achive this, let's introduce a new form of dynamic patching,
assiciating a callback to a patching site. This callback gets source and
target locations of the patching request, as well as the number of
instructions to be patched.

Dynamic patching is declared with the new ALTERNATIVE_CB and alternative_cb
directives:

	asm volatile(ALTERNATIVE_CB("mov %0, #0\n", callback)
		     : "r" (v));
or
	alternative_cb callback
		mov	x0, #0
	alternative_cb_end

where callback is the C function computing the alternative.

At the same time, we clean up this_cpu_ptr for consistency. As with
{adr,ldr,str}_l, we change the template to take the destination register

following the scheme of adr_l, and matching the newly added

12942d52f2 arm64: kpti: Use early_param for kpti= command-line option
commit b5b7dd647f upstream.

We inspect __kpti_forced early on as part of the cpufeature enable
callback which remaps the swapper page table using non-global entries.

Ensure that __kpti_forced has been updated to reflect the kpti=
command-line option before we start using it.

b1d57084b6 arm64/cpufeature: don't use mutex in bringup path
commit 63a1e1c95e upstream.

Currently, cpus_set_cap() calls static_branch_enable_cpuslocked(), which
must take the jump_label mutex.

We call cpus_set_cap() in the secondary bringup path, from the idle
thread where interrupts are disabled. Taking a mutex in this path "is a
NONO" regardless of whether it's contended, and something we must avoid.
We didn't spot this until recently, as ___might_sleep() won't warn for
this case until all CPUs have been brought up.

This patch avoids taking the mutex in the secondary bringup path. The
poking of static keys is deferred until enable_cpu_capabilities(), which
runs in a suitable context on the boot CPU. To account for the static
keys being set later, cpus_have_const_cap() is updated to use another
static key to check whether the const cap keys have been initialised,
falling back to the caps bitmap until this is the case.

This means that users of cpus_have_const_cap() gain should only gain a
single additional NOP in the fast path once the const caps are
initialised, but should always see the current cap value.

The hyp code should never dereference the caps array, since the caps are
initialized before we run the module initcall to initialise hyp. A check
is added to the hyp init code to document this requirement.

This change will sidestep a number of issues when the upcoming hotplug
locking rework is merged.

fe64d7d6ab arm64: Add hypervisor safe helper for checking constant capabilities
commit a4023f6827 upstream.

The hypervisor may not have full access to the kernel data structures
and hence cannot safely use cpus_have_cap() helper for checking the
system capability. Add a safe helper for hypervisors to check a constant
system capability, which *doesn't* fall back to checking the bitmap
maintained by the kernel. With this, make the cpus_have_cap() only
check the bitmask and force constant cap checks to use the new API
for quicker checks.
