Instead of bypassing the kernel's adaptation layer for performing EFI
runtime calls, wire up ACPI PRM handling into it. This means these calls
can no longer occur concurrently with EFI runtime calls, and will be
made from the EFI runtime workqueue. It also means any page faults
occurring during PRM handling will be identified correctly as
originating in firmware code.

Avoid duplicating the EFI arch setup and teardown routine calls numerous
times in efi_call_rts(). Instead, expand the efi_call_virt_pointer()
macro into efi_call_rts(), taking the pre and post parts out of the
switch.

Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

__efi_call_virt() exists as an alternative for efi_call_virt() for the
sole reason that ResetSystem() returns void, and so we cannot use a call
to it in the RHS of an assignment.

Given that there is only a single user, let's drop the macro, and expand
it into the caller. That way, the remaining macro can be tightened
somewhat in terms of type safety too.

Note that the use of typeof() on the runtime service invocation does not
result in an actual call being made, but it does require a few pointer
types to be fixed up and converted into the proper function pointer
prototypes.

Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

The current code that marshalls the EFI runtime call arguments to hand
them off to a async helper does so in a type unsafe and slightly messy
manner - everything is cast to void* except for some integral types that
are passed by reference and dereferenced on the receiver end.

Let's clean this up a bit, and record the arguments of each runtime
service invocation exactly as they are issued, in a manner that permits
the compiler to check the types of the arguments at both ends.

Pull EFI updates from Ard Biesheuvel:
 "Although some more stuff is brewing, the EFI changes that are ready
  for mainline are few this cycle:

   - improve the PCI DMA paranoia logic in the EFI stub

   - some constification changes

   - add statfs support to efivarfs

   - allow user space to enumerate updatable firmware resources without
     CAP_SYS_ADMIN"

* tag 'efi-next-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
  efi/libstub: Disable PCI DMA before grabbing the EFI memory map
  efi/esrt: Allow ESRT access without CAP_SYS_ADMIN
  efivarfs: expose used and total size
  efi: make kobj_type structure constant
  efi: x86: make kobj_type structure constant

The UEFI v2.9 specification includes a new memory type to be used in
environments where the OS must accept memory that is provided from its
host. Before the introduction of this memory type, all memory was
accepted eagerly in the firmware. In order for the firmware to safely
stop accepting memory on the OS's behalf, the OS must affirmatively
indicate support to the firmware. This is only a problem for AMD
SEV-SNP, since Linux has had support for it since 5.19. The other
technology that can make use of unaccepted memory, Intel TDX, does not
yet have Linux support, so it can strictly require unaccepted memory
support as a dependency of CONFIG_TDX and not require communication with
the firmware.

Enabling unaccepted memory requires calling a 0-argument enablement
protocol before ExitBootServices. This call is only made if the kernel
is compiled with UNACCEPTED_MEMORY=y

This protocol will be removed after the end of life of the first LTS
that includes it, in order to give firmware implementations an
expiration date for it. When the protocol is removed, firmware will
strictly infer that a SEV-SNP VM is running an OS that supports the
unaccepted memory type. At the earliest convenience, when unaccepted
memory support is added to Linux, SEV-SNP may take strict dependence in
it. After the firmware removes support for the protocol, this should be
reverted.
