[Minios-devel] [PATCH 23/40] arm64: fix the wrong size of the register

[Huang Shijie <shijie.huang@xxxxxxx>]

The callee-saved registers are 64bit in arm64, not 32 bit.
So this patch uses "sizeof(unsigned long)" to replace the hardcode.

This patch also fixes the wrong commit for arch_create_thread.
