IMO only three of these are actually fixes, the rest are cleanups. I've
got ahead and put everything on a branch, with

riscv: Improve description for RISCV_ISA_SVPBMT Kconfig symbol
riscv: drop cpufeature_apply_feature tracking variable
riscv: fix dependency for t-head errata

first. Those are on fixes, the whole thing is in for-next.

Thanks!
