[PATCH -next v3 0/2] support allocating crashkernel above 4G explicitly on riscv

2023-04-06 Thread Chen Jiahao
On riscv, the current crash kernel allocation logic is trying to allocate within 32bit addressible memory region by default, if failed, try to allocate without 4G restriction. In need of saving DMA zone memory while allocating a relatively large crash kernel region, allocating the reserved memory
