Merge patch series "RISC-V: Test th.sxstatus.MAEE bit before enabling MAEE" (2024-04-26 10:21:57 -0700)

----------------------------------------------------------------
RISC-V Fixes for 6.9-rc6

* A fix for TASK_SIZE on rv64/NOMMU, to reflect the lack of user/kernel
separation.
* A fix to avoid loading rv64/NOMMU kernel past the start of RAM.
* A fix for RISCV_HWPROBE_EXT_ZVFHMIN on ilp32 to avoid signed integer
overflow in the bitmask.
* The sud_test kselftest has been fixed to properly swizzle the syscall
number into the return register, which are not the same on RISC-V.
* A fix for a build warning in the perf tools on rv32.
* A fix for the CBO selftests, to avoid non-constants leaking into the
inline asm.
* A pair of fixes for T-Head PBMT errata probing, which has been renamed
MAE by the vendor.

----------------------------------------------------------------
Sorry this is late, but I found an issue in one of the patches as I was looking
through yesterday and dropped it, so I wanted to make sure everything got a
chance to make it through linux-next.

No big deal if this doesn't make it to rc6, nothing is super critical. They're
all fixes, though, so I figured it'd be better to just send this now rather
than waiting for next week.
