This series includes two parts:
1. part 1 includes patches 1-4, which improves error handling of
memory_region_init_ram, memory_region_init_ram_ptr and
memory_region_init_rom_device
2. part 2 includes patches 5-7, each fixes a bug of memory backend.
changes to v5:
- split patch 6 in v5 into 2
- use local_err instead of errp
- typo fixes
Hu Tao (7):
exec: add parameter errp to qemu_ram_alloc and qemu_ram_alloc_from_ptr
memory: add parameter errp to memory_region_init_ram
memory: add parameter errp to memory_region_init_ram_ptr
memory: add parameter errp to memory_region_init_rom_device
hostmem-ram: don't exit qemu if size of memory-backend-ram is way too
big
exec: report error when memory < hpagesize
exec: add parameter errp to gethugepagesize

Is there any awareness of the > must-exit on the mem_prealloc failure case in the higher levels? Indeed this change is irrelevant to this patch, but relevant(not quite) to patch 5. The change fixes a similar problem described in patch 5 but at the time preallocating failed. Steps to reproduce this problem are similar to the ones in patch 5, except that adds -mem-prealloc to qemu command line.
