Convert 'u8 inline' to 'inline u8' to be the same style used by the rest

Miscellanea:
jornada_ssp_reverse is an odd function.
It is declared inline but is also EXPORT_SYMBOL.
It is also apparently only used by jornada720_ssp.c
Likely the EXPORT_SYMBOL could be removed and the function
converted to static.
The addition of static and removal of EXPORT_SYMBOL was not done.

Now that explicitly executed loaders are loaded in the mmap region, we
have more freedom to decide where we position PIE binaries in the
address space to avoid possible collisions with mmap or stack regions.
4MB is chosen here mainly to have parity with x86, where this is the
traditional minimum load location, likely to avoid historically
requiring a 4MB page table entry when only a portion of the first 4MB
would be used (since the NULL address is avoided).
For ARM the position could be 0x8000, the standard ET_EXEC load address,
but that is needlessly close to the NULL address, and anyone running PIE
on 32-bit ARM will have an MMU, so the tight mapping is not needed.

Commit 7dd968163f ("bitmap: bitmap_equal memcmp optimization") was
rather more restrictive than necessary; we can use memcmp() to implement
bitmap_equal() as long as the number of bits can be proved to be a
multiple of 8. And architectures other than s390 may be able to make
good use of this optimisation.

by pci_alloc_host_bridge() as part of the struct pci_host_bridge.
Therefore, failure paths must deallocate the entire pci_host_bridge by

Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.
To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.
With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.
