Merge patch series "RISC-V: Ensure Zicbom has a valid block size" 
Andrew Jones <ajones@ventanamicro.com> says:

When a DT puts zicbom in the isa string, but does not provide a block
size, ALT_CMO_OP() will attempt to do cache operations on address
zero since the start address will be ANDed with zero. We can't simply
BUG() in riscv_init_cbom_blocksize() when we fail to find a block
size because the failure will happen before logging works, leaving
users to scratch their heads as to why the boot hung. Instead, ensure
Zicbom is disabled and output an error which will hopefully alert
people that the DT needs to be fixed. While at it, add a check that
the block size is a power-of-2 too.

  RISC-V: Ensure Zicbom has a valid block size
  RISC-V: Introduce riscv_isa_extension_check
  RISC-V: Improve use of isa2hwcap[]
