Radim Krčmář 8d164de928 riscv: use lw when reading int cpu in new_vmalloc_check 
commit e108c8a94f upstream.

REG_L is wrong, because thread_info.cpu is 32-bit, not xlen-bit wide.
The struct currently has a hole after cpu, so little endian accesses
seemed fine.

Fixes: 503638e0ba ("riscv: Stop emitting preventive sfence.vma for new vmalloc mappings")
