[PATCH 6/6] kexec: enable kexec_crash_size to support two crash kernel regions

2023-05-27 Thread Zhen Lei
The crashk_low_res should be considered by /sys/kernel/kexec_crash_size to support two crash kernel regions. Since crashk_res manages the memory with high address and crashk_low_res manages the memory with low address, crashk_low_res is shrunken only when all crashk_res is shrunken. And because whe
