linux-kernel - Re: [PATCH 02/16] Add system pointer argument to shared EFI stub related functions so they no longer use global system table pointer as they did when part of eboot.c. This code is now shared, so using a global variable as part of the interface is not that nice. Also, by avoiding any global variables in the ARM EFI stub, this allows the code to be position independent without requiring GOT fixups.
