Subject: [GIT PULL] arm64 fixes for 6.1-rc5

Hi Linus,

Please pull the arm64 fixes below. Thanks.

The following changes since commit 85f1506337f0c79a4955edfeee86a18628e3735f:

  arm64: cpufeature: Fix the visibility of compat hwcaps (2022-11-03 18:04:56 +0000)

  arm64/syscall: Include asm/ptrace.h in syscall_wrapper header. (2022-11-09 09:52:25 +0000)

----------------------------------------------------------------
arm64 fixes:

- Another fix for rodata=full. Since rodata= is not a simple boolean on
  arm64 (accepting 'full' as well), it got inadvertently broken by
  changes in the core code. If rodata=on is the default and rodata=off
  is passed on the kernel command line, rodata_full is never disabled.

- Fix gcc compiler warning of shifting 0xc0 into bits 31:24 without an
  explicit conversion to u32 (triggered by the AMPERE1 MIDR definition).

- Include asm/ptrace.h in asm/syscall_wrapper.h to fix an incomplete
  struct pt_regs type causing the BPF verifier to refuse to load a
  tracing program which accesses pt_regs.
