When a split lock is detected always make sure to disable interrupts
before returning from the trap handler.

The kernel exit code assumes that all exits run with interrupts
disabled, otherwise the SWAPGS sequence can race against interrupts and
cause recursing page faults and later panics.

The problem will only happen on CPUs with split lock disable
functionality, so Icelake Server, Tiger Lake, Snow Ridge, Jacobsville.

Voltages and current are reported by Zen CPUs. However, the means
to do so is undocumented, changes from CPU to CPU, and the raw data
is not calibrated. Calibration information is available, but again
not documented. This results in less than perfect user experience,
up to concerns that loading the driver might possibly damage
the hardware (by reporting out-of range voltages). Effectively
support for reporting voltages and current is not maintainable.
Drop it.

by new dm I/O requests or by those already in-flight can lead to
a verity corruption state, which is a misjudgment.

So, skip verity work in response to I/O error when system is shutting

Pull clk updates from Stephen Boyd:
 "The core framework got some nice improvements this time around. We
  gained the ability to get struct clk pointers from a struct clk_hw so
  that clk providers can consume the clks they provide, if they need to
  do something like that. This has been a long missing part of the clk
  provider API that will help us move away from exposing a struct clk
  pointer in the struct clk_hw. Tracepoints are added for the
  clk_set_rate() "range" functions, similar to the tracepoints we
  already have for clk_set_rate() and we added a column to debugfs to
  help developers understand the hardware enable state of clks in case
  firmware or bootloader state is different than what is expected.
  Overall the core changes are mostly improving the clk driver writing
  experience.

  At the driver level, we have the usual collection of driver updates
  and new drivers for new SoCs. This time around the Qualcomm folks
  introduced a good handful of clk drivers for various parts of three or
  four SoCs. The SiFive folks added a new clk driver for their FU740
  SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
  SoCs had lots of work done after that for various new features. One
  last thing to note in the driver area is that the i.MX driver has
  gained a new binding to support SCU clks after being on the list for
  many months. It uses a two cell binding which is sort of rare in clk
  DT bindings. Beyond that we have the usual set of driver fixes and
  tweaks that come from more testing and finding out that some
  configuration was wrong or that a driver could support being built as
  a module.

  Summary:

  Core:
   - Add some trace points for clk_set_rate() "range" functions
   - Add hardware enable information to clk_summary debugfs
   - Replace clk-provider.h with of_clk.h when possible
   - Add devm variant of clk_notifier_register()
   - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw

  New Drivers:
   - Bindings for Canaan K210 SoC clks
   - Support for SiFive FU740 PRCI
   - Camera clks on Qualcomm SC7180 SoCs
   - GCC and RPMh clks on Qualcomm SDX55 SoCs
   - RPMh clks on Qualcomm SM8350 SoCs
   - LPASS clks on Qualcomm SM8250 SoCs

  Updates:
   - DVFS support for AT91 clk driver
   - Update git repo branch for Renesas clock drivers
   - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
   - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E

The early ATAGS/DT mapping code uses SECTION_SHIFT to mask low order
bits of R2, and decides that no ATAGS/DTB were provided if the resulting
value is 0x0.

This means that on systems where DRAM starts at 0x0 (such as Raspberry
Pi), no explicit mapping of the DT will be created if R2 points into the
first 1 MB section of memory. This was not a problem before, because the
decompressed kernel is loaded at the base of DRAM and mapped using
sections as well, and so as long as the DT is referenced via a virtual
address that uses the same translation (the linear map, in this case),
things work fine.

However, commit 7a1be318 ("9012/1: move device tree mapping out of
linear region") changes this, and now the DT is referenced via a virtual
address that is disjoint from the linear mapping of DRAM, and so we need
the early code to create the DT mapping unconditionally.

So let's create the early DT mapping for any value of R2 != 0x0.

When linking a multi_v7_defconfig + CONFIG_KASAN=y kernel with

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- LLVM=1 zImage
ld.lld: error: section: .exit.data is not contiguous with other relro sections

LLD defaults to '-z relro', which is unneeded for the kernel because
program headers are not used nor is there any position independent code
generation or linking for ARM. Add '-z norelro' to LDFLAGS_vmlinux to
avoid this error.

Macros used as functions can be problematic from the compiler perspective.
There was a build failure report caused primarily because of non reference
of an argument variable. Hence convert PUD level pgtable helper macros into
functions in order to avoid such problems in the future. In the process, it

fixes the argument variables sequence in set_pud() which probably remained
hidden for being a macro.

Commit f77ac2e3 ("ARM: 9030/1: entry: omit FP emulation for UND
exceptions taken in kernel mode") failed to take into account that there
is in fact a case where we relied on this code path: during boot, the
VFP detection code issues a read of FPSID, which will trigger an undef
exception on cores that lack VFP support.

So let's reinstate this logic using an undef hook which is registered
only for the duration of the initcall to vpf_init(), and which sets
VFP_arch to a non-zero value - as before - if no VFP support is present.
