| H A D | efi_stub_32.S | 59f2a619 Tue Jan 21 02:44:43 CST 2020 Ard Biesheuvel <ardb@kernel.org> efi: Add 'runtime' pointer to struct efi
Instead of going through the EFI system table each time, just copy the
runtime services table pointer into struct efi directly. This is the
last use of the system table pointer in struct efi, allowing us to
drop it in a future patch, along with a fair amount of quirky handling
of the translated address.
Note that usually, the runtime services pointer changes value during
the call to SetVirtualAddressMap(), so grab the updated value as soon
as that call returns. (Mixed mode uses a 1:1 mapping, and kexec boot
enters with the updated address in the system table, so in those cases,
we don't need to do anything here)
