In addition to two other series that are in flight, regarding the EFI runtime call assembly wrappers [0], and the use of restricted memory permissions for mapping EFI runtime service memory regions [1], here's another batch of fixes and cleanups for the early EFI code. Patches #1 .. #3 are fixes for the code that is currently queued in tip/efi/core. Patch #4 fixes an ancient issue in the EFI boot code where it doesn't map the memory containing the EFI vendor name string correctly. Patch #5 redefines the macro __efiapi to __attribute__((regparm(0))) on 32-bit x86 so we no longer have to cast every function pointer that requires that annotation. Patch #6 refactors efi_runtime_init() so we no longer have two mostly identical copies of the same code for 32-bit and 64-bit. Patch #7 cleans up efi_systab_init() and also gets rid of the 'efi_phys' data structure that exists for no good reason.
