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.

v2 is split for easy backporting.

Thanks.

v2:
* transform [v1 2/3] into [v2 1-2/4] to simplify backports [Alex]
* tested and reviewed by Alex
v1: https://lore.kernel.org/lkml/20250722160556.2216925-2-rkrcmar@xxxxxxxxxxxxxxxx/

Radim Krčmář (4):
riscv: use lw when reading int cpu in new_vmalloc_check
riscv: use lw when reading int cpu in asm_per_cpu
riscv: use TASK_TI_CPU instead of TASK_TI_CPU_NUM
riscv: pack rv64 thread_info better
