Merge tag 'riscv-for-linus-7.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Paul Walmsley:

 - 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
