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
