Pull kcfi updates from Kees Cook:
"This replaces the prior support for Clang's standard Control Flow
Integrity (CFI) instrumentation, which has required a lot of special
conditions (e.g. LTO) and work-arounds.
The new implementation ("Kernel CFI") is specific to C, directly
designed for the Linux kernel, and takes advantage of architectural
features like x86's IBT. This series retains arm64 support and adds
x86 support.
GCC support is expected in the future[1], and additional "generic"
architectural support is expected soon[2].
Summary:
- treewide: Remove old CFI support details
- arm64: Replace Clang CFI support with Clang KCFI support
- x86: Introduce Clang KCFI support"

With -fsanitize=kcfi, we no longer need function_nocfi() as
the compiler won't change function references to point to a
jump table. Remove all implementations and uses of the macro.

With -fsanitize=kcfi, CONFIG_CFI_CLANG no longer has issues
with address space confusion in functions that switch to linear
mapping. Now that the indirectly called assembly functions have
type annotations, drop the __nocfi attributes.

With -fsanitize=kcfi, CFI always traps. Add arm64 support for handling CFI
failures. The registers containing the target address and the expected type
are encoded in the first ten bits of the ESR as follows:
- 0-4: n, where the register Xn contains the target address
- 5-9: m, where the register Wm contains the type hash
This produces the following oops on CFI failure (generated using lkdtm):

With CONFIG_CFI_CLANG, assembly functions indirectly called from C
code must be annotated with type identifiers to pass CFI checking. Use
SYM_TYPED_FUNC_START for the indirectly called functions, and ensure
we emit `bti c` also with SYM_TYPED_FUNC_START.

- Bjorn Andersson's email address changes in the MAINTAINERS file
- Multiple minor fixes to Qualcomm dts files, and a change to the

cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*,
while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'.
Multiplying max frequency by 1000 can potentially result in overflow --
multiplying by 1000ULL instead should avoid that...

Since commit:
ee017ee353506fce ("arm64/mm: avoid fixmap race condition when create pud mapping")
... once the kernel leave the SYSTEM_BOOTING state, the fixmap pagetable
entries are protected by the fixmap_lock mutex.
The new KPTI rewrite code uses __create_pgd_mapping() to create a
temporary pagetable. This happens in atomic context, after secondary
CPUs are brought up and the kernel has left the SYSTEM_BOOTING state.
Hence we try to acquire a mutex in atomic context, which is generally
unsound (though benign in this case as the mutex should be free and all
other CPUs are quiescent).
This patch avoids the issue by pulling the mutex out of alloc_init_pud()
and calling it at a higher level in the pagetable manipulation code.
This allows it to be used without locking where one CPU is known to be
in exclusive control of the machine, even after having left the
SYSTEM_BOOTING state.

With commit 0c24e061196c ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.
Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.

Currently, we limited the voltages from the PMIC very strictly. This
causes an issue with one Toradex SKU that uses a consumer-grade chip
that is capable of going up to 1.8GHz at 1.00V.
Extend the ranges to min/max values of the SoC operating ranges (table
10) in the datasheet. Detailed explanation as follows:
BUCK2:
- As already described above, the SKU with the consumer-grade chip
needs a voltage of at least 1.00V. 1.05V is chosen now as this is
listed as the maximum. Both industrial and consumer-grade chips have
an absolute maximum rating of 1.15V which makes it still safe to put
1.05V
- Lower the regulator-min value to the smallest value allowed from the
Quad-A53, 1.2GHz version of the SoC
BUCK3:
- This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and
VDD_DRAM.
- Use the smallest value of these three inputs as the regulator-min
- Use the largest value of these three inputs as the regulator-max
LDO2:
- This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a
single nominal input voltage just put this in the middle of 0.8V.

The PGC (power gating controller) already handles the reset for the
GPUMIX power domain. By specifying it within the device tree the reset
it issued a 2nd time. This confuses the hardware during power up and
sporadically hangs the SoC. Fix this by removing the reset property and
let the hardware handle the reset.

We've found the AUX channel to be less reliable with PCLK_EDP at a
higher rate (typically 25 MHz). This is especially important on systems
with PSR-enabled panels (like Gru-Kevin), since we make heavy, constant
use of AUX.
According to Rockchip, using any rate other than 24 MHz can cause
"problems between syncing the PHY an PCLK", which leads to all sorts of
unreliabilities around register operations.

The Gru-Bob board does not have a pull-up resistor on its
WLAN_HOST_WAKE# pin, but Kevin does. The production/vendor kernel
specified the pin configuration correctly as a pull-up, but this didn't
get ported correctly to upstream.
This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent
wakeup behavior.
Note that bt_host_wake_l has a similar dynamic, but apparently the
upstream choice was to redundantly configure both internal and external
pull-up on Kevin (see the "Kevin has an external pull up" comment in
rk3399-gru.dtsi). This doesn't cause any functional problem, although
it's perhaps wasteful.

__cpu_setup() was changed to take the actual number of VA bits in x0,
however the resume path was not updated at the same time.
Load `vabits_actual` in the resume path, to ensure that the correct
number of VA bits is used.
This fixes booting v6.0-rc kernels on my Juno.

If allocating memory for the target SVE state in za_set() fails we clear
TIF_SME for the ptracing task which is obviously not correct. If we are
here we know that the target task already had neither TIF_SVE nor
TIF_SME set since we only need to allocate if either the target had not
used either SVE or SME and had no need to allocate state before or we
just changed the vector length with vec_set_vector_length() which clears
TIF_ for us on allocation failure so just remove the clear entirely.

GCC does not insert a `bti c` instruction at the beginning of a function
when it believes that all callers reach the function through a direct
branch[1]. Unfortunately the logic it uses to determine this is not
sufficiently robust, for example not taking account of functions being
placed in different sections which may be loaded separately, so we may
still see thunks being generated to these functions. If that happens,
the first instruction in the callee function will result in a Branch
Target Exception due to the missing landing pad.
While this has currently only been observed in the case of modules
having their main code loaded sufficiently far from their init section
to require thunks it could potentially happen for other cases so the
safest thing is to disable BTI for the kernel when building with an
affected toolchain.

Kernel output is unaffected, as it is printed using polling.
