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].

If the architecture knows at compile time that there is no VDSO capable
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.

do_coarse() is similar to do_hres() except that it never fails.
Change its type to int instead of void and let it always return success (0)
to simplify the call site.

Since all the architectures that support the generic vDSO library have
been converted to support the 32 bit fallbacks it is not required
anymore to check the return value of __cvdso_clock_get*time32_common()
before updating the old_timespec fields.
Remove the related checks from the generic vdso library.

Add padding to ufshcd_host and ufshcd_hba_variant_ops UFS, and mmc_host

ABI stable. These fields are only for the purposes of keeping the ABI

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
