bd35c77e32 x86/tsc: Add tsc_early_khz command line parameter
Changing base clock frequency directly impacts TSC Hz but not CPUID.16h
value. An overclocked CPU supporting CPUID.16h and with partial CPUID.15h
support will set TSC KHZ according to "best guess" given by CPUID.16h
relying on tsc_refine_calibration_work to give better numbers later.
tsc_refine_calibration_work will refuse to do its work when the outcome is
off the early TSC KHZ value by more than 1% which is certain to happen on
an overclocked system.

Fix this by adding a tsc_early_khz command line parameter that makes the
kernel skip early TSC calibration and use the given value instead.

This allows the user to provide the expected TSC frequency that is closer
to reality than the one reported by the hardware, enabling
tsc_refine_calibration_work to do meaningful error checking.

[ tglx: Made the variable __initdata as it's only used on init and
        removed the error checking in the argument parser because
	kstrto*() only stores to the variable if the string is valid ]

Qualcomm ARM64 DT updates for v5.8

For SDM845 this defines the IPA network accelerator and the CCI camera
control bus, it defines the required UFS reset and adds WiFi for the
Lenovo Yoga C630 and defines GPIO pin names and adds OV8856 and OC7251
camera nodes for DB845c.

For SC7180 it adds GPU support, defines the modem remoteproc, adds the
IPA network accelerator, Coresight and ETM support, adds cpuidle low
power states and updates the CPUs' compatible.

For SM8250 it adds regulators from the PM8150, PM8150L and PM8009 and
adds voltage corners, it defines the nodes for UFS PHY and controller
and finally corrects a typo in the PDC node to make SPMI functional.

For MSM8916 I2C1 and I2C5 are defined, a node for the CCI camera control
interface bus is added and Coresight is disabled by default to match
some product configurations. The Samsung A3U gained display support and
Samsung A5U gained touchscreen support.

MSM8996 now property describes the power supply chain for the GPU, the
CCI camera control interface bus is added and the DB820c has the
regulators of the secondary PMIC defined.

For QCS404 USB PHYs and controllers are defined and wired up for the
EVB.

SDM630/SDM660 platform support is added and the Xiaomi Redmi Note 7
defined.

It also contains a number of changes throughout to improve DT binding
compliance.

8356c379cf RISC-V: gp_in_global needs register keyword
The Intel kernel build robot recently pointed out that I missed the
register keyword on this one when I refactored the code to remove local
register variables (which aren't supported by LLVM).  GCC's manual
indicates that global register variables must have the register keyword,
As far as I can tell lacking the register keyword causes GCC to ignore
the __asm__ and treat this as a regular variable, but I'm not sure how
that didn't show up as some sort of failure.

bc2bf338d5 exec: Remove recursion from search_binary_handler
Recursion in kernel code is generally a bad idea as it can overflow
the kernel stack.  Recursion in exec also hides that the code is
looping and that the loop changes bprm->file.

Instead of recursing in search_binary_handler have the methods that
would recurse set bprm->interpreter and return 0.  Modify exec_binprm
to loop when bprm->interpreter is set.  Consolidate all of the
reassignments of bprm->file in that loop to make it clear what is
going on.

The structure of the new loop in exec_binprm is that all errors return
immediately, while successful completion (ret == 0 &&
!bprm->interpreter) just breaks out of the loop and runs what
exec_bprm has always run upon successful completion.

Fail if the an interpreter is being call after execfd has been set.
The code has never properly handled an interpreter being called with
execfd being set and with reassignments of bprm->file and the
assignment of bprm->executable in generic code it has finally become
possible to test and fail when if this problematic condition happens.

With the reassignments of bprm->file and the assignment of
bprm->executable moved into the generic code add a test to see if
bprm->executable is being reassigned.

In search_binary_handler remove the test for !bprm->file.  With all
reassignments of bprm->file moved to exec_binprm bprm->file can never
be NULL in search_binary_handler.

2a5bc6c47b arm64/cpufeature: Add explicit ftr_id_isar0[] for ID_ISAR0 register
ID_ISAR0[31..28] bits are RES0 in ARMv8, Reserved/UNK in ARMv7. Currently
these bits get exposed through generic_id_ftr32[] which is not desirable.
Hence define an explicit ftr_id_isar0[] array for ID_ISAR0 register where
those bits can be hidden.

8659a0e0ef powerpc/64s: Disable STRICT_KERNEL_RWX
Several strange crashes have been eventually traced back to
STRICT_KERNEL_RWX and its interaction with code patching.

Various paths in our ftrace, kprobes and other patching code need to
be hardened against patching failures, otherwise we can end up running
with partially/incorrectly patched ftrace paths, kprobes or jump
labels, which can then cause strange crashes.

Although fixes for those are in development, they're not -rc material.

There also seem to be problems with the underlying strict RWX logic,
which needs further debugging.

So for now disable STRICT_KERNEL_RWX on 64-bit to prevent people from
enabling the option and tripping over the bugs.

Fixes: 1e0fc9d1eb ("powerpc/Kconfig: Enable STRICT_KERNEL_RWX for some configs")
