Subject: [PATCH 0/3] riscv: minor thread_info.cpu improvements

Hello,

I noticed that we give thread_info.cpu two different names in the
assembly, load it as a wider type, and store it suboptimally.

The patches are split for easy review instead of easy backporting:
I could split [2/3] into two patches, and move them before [1/3].
Do we expect someone to actually backport the fixes?

Thanks.

  riscv: use TASK_TI_CPU instead of TASK_TI_CPU_NUM
  riscv: use lw instead of REG_L when reading int cpu
  riscv: pack rv64 thread_info better
