Subject: [PATCH -next v3 0/2] Remove unused variables in x86/boot

This series removes some unused variables in x86/boot, and add the
"-Wall" flag to Makefile, which is the old problem of x86 not sharing
makefiles.

Changes since v2:
- Add "frame-address" flag and "-std=gnu11" to 
  x86/boot/compressed/Makefile to fix warnings when "-Wall" flag added.
- Declare the variable "i" within the for loop to reslove unused 
  variable warning.
- Delete __efi_get_rsdp_addr function when CONFIG_EFI is disabled to 
  resolve unused function warning.

v2 at:
https://lore.kernel.org/all/20220927081512.2456624-1-lizetao1@huawei.com/

Changes since v1:
- Add "-Wall" flag to x86/boot/compressed/Makefile
- Remove unused variables "et" in efi_get_system_table() and "ret" in
  efi_get_conf_table()
- Remove unused variables "ret" in __efi_get_rsdp_addr() and
  "nr_tables" in efi_get_rsdp_addr()
