Subject: [GIT PULL] RISC-V updates for v7.3-rc3
Date: Fri, 11 Sep 2026 11:55:00 -0600 (MDT)	[thread overview]
Message-ID: <bca66c44-faf3-27b1-daec-1fe594804354@kernel.org> (raw)

Linus,

Please pull these RISC-V updates for v7.3-rc3.  From a RISC-V point of 
view, there's one notable fix here, reverting an earlier bogus fix to the 
pointer masking code.  Fortunately the practical impact appears to be 
small.


- Paul

  riscv: skip software algning code for HAVE_EFFICIENT_UNALIGNED_ACCESS (2026-09-02 11:47:08 -0600)

----------------------------------------------------------------
RISC-V updates for v7.3-rc3

- Revert a bad fix, likely LLM-generated, in the pointer masking code
  that confused the RISC-V hardware pointer masking implementation
  with the Linux kernel tagged address feature

- Fix unexpected faults caused by kprobe instruction slot writes when
  !CONFIG_STRICT_MODULE_RWX

- Fix unexpected faults on minimal configurations during runtime code
  patching on !CONFIG_STRICT_MODULE_RWX systems

- Fix a misplaced variable clear causing incorrect reuse of previous
  values in the RISC-V hardware feature probing code

- Fix two bugs in the PMU SBI perf code on rv32: use BIT_ULL rather
  than BIT on 64-bit masks; and use a bitmap rather than an unsigned
  long on a quantity that can exceed 32 bits

And a few miscellaneous cleanups:

- Avoid a potential dereference-before-NULL-pointer-check bug in the
  PMU SBI perf driver

- Simplify the rv32 bug table code by using
  CONFIG_GENERIC_BUG_RELATIVE_POINTERS (following x86 and PPC)

- Report the RISC-V standard ISA extensions Z[v]fhmin when support is
  claimed for the superset RISC-V standard ISA extensions Z[v]fh; and
  simplify our FPU test code to only check for the presence of the D
  extension

- Use an existing kernel string helper in place of some open-coded
  code in kernel/usercfi.c

- Fix some yamllint issues in the RISC-V DT bindings for CPUs

- Convert one use of __ASSEMBLY__ to __ASSEMBLER__ that snuck into the
  RISC-V CFI selftest code

- Update the translation for the simplified Chinese translation of the
  RISC-V kernel patch acceptance policy
