Subject: [GIT PULL] RISC-V updates for v7.2-rc2
Date: Fri, 3 Jul 2026 12:07:31 -0600 (MDT)	[thread overview]
Message-ID: <98c1a609-5ce9-5703-77d4-bdb2d92d7338@kernel.org> (raw)

Linus,

Please pull these RISC-V updates for v7.2-rc2.  Nothing too
remarkable, I think.  The signficant kernel size changes on
SMP-capable configs are due to increasing the default NR_CPUS.

thanks,

- Paul

  riscv: probes: save original sp in rethook trampoline (2026-06-30 18:46:54 -0600)

----------------------------------------------------------------
RISC-V updates for v7.2-rc2

- Fix a crash when a kretprobe reads from the stack

- Fix an issue with the build-time mcount sorter that broke ftrace

- Fix the rv32 IRQ stack frame padding to match the ABI

- Only defer IOMMU configuration during initialization.  This avoids
  an issue where IOMMU configuration could be indefinitely deferred

- Add the missing build salt to the vDSO

- Now that RISC-V systems with higher numbers of cores are starting to
  become available, raise NR_CPUS for RISC-V to 256

- Clean up some warnings from sparse caused by the RISC-V-optimized
  RAID6 code

- Clean up our __cpu_up() code with a few minor fixes
