Fix this when building on 32-bit:
arch/x86/platform/efi/efi.c: In function ‘__efi_enter_virtual_mode’:
arch/x86/platform/efi/efi.c:911:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
(efi_memory_desc_t *)pa);
^
arch/x86/platform/efi/efi.c:918:5: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
(efi_memory_desc_t *)pa);
^
The @pa local variable is declared as phys_addr_t and that is a u64 when
CONFIG_PHYS_ADDR_T_64BIT=y. (The last is enabled on 32-bit on a PAE
build.)
However, its value comes from __pa() which is basically doing pointer
arithmetic and checking, and returns unsigned long as it is the native
pointer width.
So let's use an unsigned long too. It should be fine to do so because
the later users cast it to a pointer too.
