x86/efi: Preserve segment registers in mixed mode I was triggering a #GP(0) from userland when running with CONFIG_EFI_MIXED and CONFIG_IA32_EMULATION, from what looked like register corruption. Turns out that the mixed mode code was trashing the contents of %ds, %es and %ss in __efi64_thunk(). Save and restore the contents of these segment registers across the call to __efi64_thunk() so that we don't corrupt the CPU context. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
