[GIT PULL] RISC-V updates for late v7.2-rc

[Paul Walmsley]

Linus,

Please pull these RISC-V updates for late v7.2-rc.  Nothing too
notable here; all of these fix significant issues that would be
good to resolve before v7.2 is tagged.

thanks,


- Paul

  riscv: lib: Fix ZBB strnlen reading past count boundary (2026-08-08 11:45:33 -0600)

----------------------------------------------------------------
RISC-V updates for late v7.2-rc

- Fix a fault caused when the RISC-V Zbb-enabled strlen() is executed
  on a string that ends right before a page boundary, when the next
  page is unmapped

- Fix a race with the misaligned vector performance testing code that
  can prevent the outcome of the test from being stored into the vDSO
  cache

- Fix a kernel warning generated by the ftrace code when
  ftrace_modify_call_code() runs against a ftrace-traced function
  where a kprobe has already been attached.  This shows up in the bpf
  kselftests
