commit 35b6b28e69985eafb20b3b2c7bd6eca452b56b53 upstream.
When branch target identifiers are in use, code reachable via an
indirect branch requires a BTI landing pad at the branch target site.
When building FTRACE_WITH_REGS atop patchable-function-entry, we miss
BTIs at the start start of the `ftrace_caller` and `ftrace_regs_caller`
trampolines, and when these are called from a module via a PLT (which
will use a `BR X16`), we will encounter a BTI failure, e.g.

Fix this by adding the required `BTI C`, as we only require these to be
reachable via BL for direct calls or BR X16/X17 for PLTs. For now, these
are open-coded in the function prologue, matching the style of the
`__hwasan_tag_mismatch` trampoline.
In future we may wish to consider adding a new SYM_CODE_START_*()
variant which has an implicit BTI.
When ftrace is built atop mcount, the trampolines are marked with
SYM_FUNC_START(), and so get an implicit BTI. We may need to change
these over to SYM_CODE_START() in future for RELIABLE_STACKTRACE, in
case we need to apply special care aroud the return address being
rewritten.

commit 1f80d15020d7f130194821feb1432b67648c632d upstream.
Having a signed (1 << 31) constant for TCR_EL2_RES1 and CPTR_EL2_TCPAC
causes the upper 32-bit to be set to 1 when assigning them to a 64-bit
variable. Bit 32 in TCR_EL2 is no longer RES0 in ARMv8.7: with FEAT_LPA2
it changes the meaning of bits 49:48 and 9:8 in the stage 1 EL2 page
table entries. As a result of the sign-extension, a non-VHE kernel can
no longer boot on a model with ARMv8.7 enabled.
CPTR_EL2 still has the top 32 bits RES0 but we should preempt any future
problems
Make these top bit constants unsigned as per commit df655b75c43f
("arm64: KVM: Avoid setting the upper 32 bits of VTCR_EL2 to 1").

[ Upstream commit 94902d849e85093aafcdbea2be8e2beff47233e6 ]
As Vincent reports in:
https://lore.kernel.org/r/20211118163417.21617-1-vincent.whitchurch@axis.com
The put_user() in schedule_tail() can get stuck in a livelock, similar
to a problem recently fixed on riscv in commit:
285a76bb2cf51b0c ("riscv: evaluate put_user() arg before enabling user access")
In __raw_put_user() we have a critical section between
uaccess_ttbr0_enable() and uaccess_ttbr0_disable() where we cannot
safely call into the scheduler without having taken an exception, as
schedule() and other scheduling functions will not save/restore the
TTBR0 state. If either of the `x` or `ptr` arguments to __raw_put_user()
contain a blocking call, we may call into the scheduler within the
critical section. This can result in two problems:
1) The access within the critical section will occur without the
required TTBR0 tables installed. This will fault, and where the
required tables permit access, the access will be retried without the
required tables, resulting in a livelock.
2) When TTBR0 SW PAN is in use, check_and_switch_context() does not
modify TTBR0, leaving a stale value installed. The mappings of the
blocked task will erroneously be accessible to regular accesses in
the context of the new task. Additionally, if the tables are
subsequently freed, local TLB maintenance required to reuse the ASID
may be lost, potentially resulting in TLB corruption (e.g. in the
presence of CnP).
The same issue exists for __raw_get_user() in the critical section
between uaccess_ttbr0_enable() and uaccess_ttbr0_disable().
A similar issue exists for __get_kernel_nofault() and
__put_kernel_nofault() for the critical section between
__uaccess_enable_tco_async() and __uaccess_disable_tco_async(), as the
TCO state is not context-switched by direct calls into the scheduler.
Here the TCO state may be lost from the context of the current task,
resulting in unexpected asynchronous tag check faults. It may also be
leaked to another task, suppressing expected tag check faults.
To fix all of these cases, we must ensure that we do not directly call
into the scheduler in their respective critical sections. This patch
reworks __raw_put_user(), __raw_get_user(), __get_kernel_nofault(), and
__put_kernel_nofault(), ensuring that parameters are evaluated outside
of the critical sections. To make this requirement clear, comments are
added describing the problem, and line spaces added to separate the
critical sections from other portions of the macros.
For __raw_get_user() and __raw_put_user() the `err` parameter is
conditionally assigned to, and we must currently evaluate this in the
critical section. This behaviour is relied upon by the signal code,
which uses chains of put_user_error() and get_user_error(), checking the
return value at the end. In all cases, the `err` parameter is a plain
int rather than a more complex expression with a blocking call, so this
is safe.
In future we should try to clean up the `err` usage to remove the
potential for this to be a problem.
Aside from the changes to time of evaluation, there should be no
functional change as a result of this patch.

commit d3eb70ead6474ec16f976fcacf10a7a890a95bd3 upstream.
trans_pgd_create_copy() can hit "VM_BUG_ON(mm != &init_mm)" in the
function pmd_populate_kernel().
This is the combined consequence of commit 5de59884ac0e ("arm64:
trans_pgd: pass NULL instead of init_mm to *_populate functions"), which
replaced &init_mm with NULL and commit 59511cfd08f3 ("arm64: mm: use XN
table mapping attributes for user/kernel mappings"), which introduced
the VM_BUG_ON.
Since the former sounds reasonable, it is better to work on the later.
From the perspective of trans_pgd, two groups of functions are
considered in the later one:
pmd_populate_kernel()
mm == NULL should be fixed, else it hits VM_BUG_ON()
p?d_populate()
mm == NULL means PXN, that is OK, since trans_pgd only copies a
linear map, no execution will happen on the map.
So it is good enough to just relax VM_BUG_ON() to disregard mm == NULL

[ Upstream commit 50a8d3315960c74095c59e204db44abd937d4b5d ]
We currently walk the hypervisor stage-1 page-table towards the end of
hyp init in nVHE protected mode and adjust the host page ownership
attributes in its stage-2 in order to get a consistent state from both
point of views. The walk is done on the entire hyp VA space, and expects
to only ever find page-level mappings. While this expectation is
reasonable in the half of hyp VA space that maps memory with a fixed
offset (see the loop in pkvm_create_mappings_locked()), it can be
incorrect in the other half where nothing prevents the usage of block
mappings. For instance, on systems where memory is physically aligned at
an address that happens to maps to a PMD aligned VA in the hyp_vmemmap,
kvm_pgtable_hyp_map() will install block mappings when backing the
hyp_vmemmap, which will later cause finalize_host_mappings() to fail.
Furthermore, it should be noted that all pages backing the hyp_vmemmap
are also mapped in the 'fixed offset range' of the hypervisor, which
implies that finalize_host_mappings() will walk both aliases and update
the host stage-2 attributes twice. The order in which this happens is
unpredictable, though, since the hyp VA layout is highly dependent on
the position of the idmap page, hence resulting in a fragile mess at
best.
In order to fix all of this, let's restrict the finalization walk to
only cover memory regions in the 'fixed-offset range' of the hyp VA
space and nothing else. This not only fixes a correctness issue, but
will also result in a slighlty faster hyp initialization overall.

The entry/exit latency and minimum residency in state for the idle
states of MSM8998 were ..bad: first of all, for all of them the
timings were written for CPU sleep but the min-residency-us param
was miscalculated (supposedly, while porting this from downstream);
Then, the power collapse states are setting PC on both the CPU
cluster *and* the L2 cache, which have different timings: in the
specific case of L2 the times are higher so these ones should be
taken into account instead of the CPU ones.
This parameter misconfiguration was not giving particular issues
because on MSM8998 there was no CPU scaling at all, so cluster/L2
power collapse was rarely (if ever) hit.
When CPU scaling is enabled, though, the wrong timings will produce
SoC unstability shown to the user as random, apparently error-less,
sudden reboots and/or lockups.
This set of parameters are stabilizing the SoC when CPU scaling is
ON and when power collapse is frequently hit.

[ Upstream commit 9dc232a8ab18bb20f1dcb03c8e049e3607f3ed15 ]
The id argument of ARM64_FTR_REG_OVERRIDE() is used for two purposes:
one as the system register encoding (used for the sys_id field of
__ftr_reg_entry), and the other as the register name (stringified
and used for the name field of arm64_ftr_reg), which is debug
information. The id argument is supposed to be a macro that
indicates an encoding of the register (eg. SYS_ID_AA64PFR0_EL1, etc).
ARM64_FTR_REG(), which also has the same id argument,
uses ARM64_FTR_REG_OVERRIDE() and passes the id to the macro.
Since the id argument is completely macro-expanded before it is
substituted into a macro body of ARM64_FTR_REG_OVERRIDE(),
the stringified id in the body of ARM64_FTR_REG_OVERRIDE is not
a human-readable register name, but a string of numeric bitwise
operations.
Fix this so that human-readable register names are available as
debug information.

At the moment, playing audio on Secondary MI2S will just end up getting
stuck, without actually playing any audio. This happens because the wrong
bit clock is configured when playing audio on Secondary MI2S.
The PRI_I2S_CLK (better name: SPKR_I2S_CLK) is used by the SPKR audio mux
block that provides both Primary and Secondary MI2S.
The SEC_I2S_CLK (better name: MIC_I2S_CLK) is used by the MIC audio mux
block that provides Tertiary MI2S. Quaternary MI2S is also part of the
MIC audio mux but has its own clock (AUX_I2S_CLK).
This means that (quite confusingly) the SEC_I2S_CLK is not actually
used for Secondary MI2S as the name would suggest. Secondary MI2S
needs to have the same clock as Primary MI2S configured.
Fix the clock list for the lpass node in the device tree and add
a comment to clarify this confusing naming. With these changes,
audio can be played correctly on Secondary MI2S.

The sc7180's dynamic-power-coefficient violates the device tree bindings.
The bindings (arm/cpus.yaml) say that the units for the
dynamic-power-coefficient are supposed to be "uW/MHz/V^2". The ones for
sc7180 aren't this. Qualcomm arbitrarily picked 100 for the "little" CPUs
and then picked a number for the big CPU based on this.
At the time, there was a giant dicussion about this. Apparently Qualcomm
Engineers were instructed not to share the actual numbers here. As part
of the discussion, I pointed out [1] that these numbers shouldn't really
be secret since once a device is shipping anyone can just run a script
and produce them. This patch is the result of running the script I posted
in that discussion on sc7180-trogdor-coachz, which is currently available
for purchase by consumers.

As you can see, the calculations aren't perfectly consistent but
roughly you could say about 480 for big and 137 for little.
The ratio between these numbers isn't quite the same as the ratio
between the two numbers that Qualcomm used. Perhaps this is because
Qualcomm measured something slightly different than the 64-bit version
of dhrystone 2.2 or perhaps it's because they fudged these numbers a
bit (and fudged the capacity-dmips-mhz). As per discussion [2], let's
use the numbers I came up with and also un-fudge
capacity-dmips-mhz. While unfudging capacity-dmips-mhz, let's scale it
so that bigs are 1024 which seems to be the common practice.
In general these numbers don't need to be perfectly exact. In fact,
they can't be since the CPU power depends a lot on what's being run on
the CPU and the big/little CPUs are each more or less efficient in
different operations. Historically running the 32-bit vs. 64-bit
versions of dhrystone produced notably different numbers, though I
didn't test this time.
We also need to scale all of the sustainable-power numbers by the same
amount. I scale ones related to the big CPUs by the adjustment I made
to the big dynamic-power-coefficient and the ones related to the
little CPUs by the adjustment I made to the little
dynamic-power-coefficient.

commit 8bb084119f1acc2ec55ea085a97231e3ddb30782 upstream.
Since ARMv8.0 the upper 32 bits of ESR_ELx have been RES0, and recently
some of the upper bits gained a meaning and can be non-zero. For
example, when FEAT_LS64 is implemented, ESR_ELx[36:32] contain ISS2,
which for an ST64BV or ST64BV0 can be non-zero. This can be seen in ARM
DDI 0487G.b, page D13-3145, section D13.2.37.
Generally, we must not rely on RES0 bit remaining zero in future, and
when extracting ESR_ELx.EC we must mask out all other bits.
All C code uses the ESR_ELx_EC() macro, which masks out the irrelevant
bits, and therefore no alterations are required to C code to avoid
consuming irrelevant bits.
In a couple of places the KVM assembly extracts ESR_ELx.EC using LSR on
an X register, and so could in theory consume previously RES0 bits. In
both cases this is for comparison with EC values ESR_ELx_EC_HVC32 and
ESR_ELx_EC_HVC64, for which the upper bits of ESR_ELx must currently be
zero, but this could change in future.
This patch adjusts the KVM vectors to use UBFX rather than LSR to
extract ESR_ELx.EC, ensuring these are robust to future additions to
ESR_ELx.

This reverts a clock change in the Qualcomm RB5 devicetree which in some
combinations of firmware and configuration causes the device to crash
during boot.
Data on an adjacent platform indicates that this is probably not be the
root cause of the problem, but this resolves the regression seen on RB5
and will allow the SM8250 platform to boot v5.15.

This upstream commit broke AOSP (post Android 12 merge) build
