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!
