In the process of creating the source file of a module modpost injects a
set of includes that are not required if the compilation unit is
statically built into the kernel.
The order of inclusion of the headers can cause redefinition problems
(e.g.):
In file included from include/linux/elf.h:5:0,
from include/linux/module.h:18,
from crypto/arc4.mod.c:2:
#define ELF_OSABI ELFOSABI_LINUX
In file included from include/linux/elfnote.h:62:0,
from include/linux/build-salt.h:4,
from crypto/arc4.mod.c:1:
include/uapi/linux/elf.h:363:0: note: this is the location of
the previous definition
#define ELF_OSABI ELFOSABI_NONE
The issue was exposed during the development of the series [1].

clocksource supported it makes sense to optimize the guts of the high
resolution parts of the VDSO out at build time. Add a helper function to
check whether the VDSO should be high resolution capable and provide a stub
which can be overridden by an architecture.

clock_gettime32 and clock_getres_time32 should be compiled only with the
32 bit vdso library.
Expose BUILD_VDSO32 when arm64 compat is compiled, to provide an
indication to the generic library to include these symbols.

If free blocks hole is smaller than discard_granularity,
TRIM to this range can be skipped.
Fix this by changing the granularity to 4kb at dm-bow layer,
not to skip TRIM to every tiny free blocks.

Add padding to ufshcd_host and ufshcd_hba_variant_ops UFS, and mmc_host
in MMC to allow expansions in future if necessary, while keeping the
ABI stable. These fields are only for the purposes of keeping the ABI
stable, and in particular are *NOT* for vendor use.

Make mmc core able to use the blk-crypto framework for inline
encryption. This patch introduces a pointer to struct keyslot_manager
to struct mmc_host, and handles setting up the request_queue for
devices using that keyslot_manager appropriately. It also inits struct
mmc_request's inline encryption fields before it's passed to
mmc_host::ops->request.
Users of the core code in host/ (e.g. cqhci.c) should initialize the
keyslot_manager in struct mmc_host appropriately, if they want to
support inline encryption. They should also handle any inline
encryption related work necessary when mmc_host::ops->request is
called.
This patch is only compile tested, as I don't have a device to
actually test these patches. Enable CONFIG_MMC_CRYPTO to test
