Fix the x86 test_get_len tool to have the right include paths in the right
order (it includes a non-exported kernel header directly), otherwise errors
like the following occur:
/data/fs/linux-2.6-hdr/include/linux/types.h:18:26: error: conflicting types
for 'fd_set'
Fix a build failure in the x86 insn_sanity program after the UAPI split. The
problem is that insn_sanity.c #includes arch/x86/lib/insn.c - which uses the
kernel string header. This leads to conflicts for various definitions against
the /usr/include/ headers.
linux/string.h can be replaced with
Set up uapi/asm/Kbuild.asm. This requires the mandatory headers to be
dynamically detected. The same goes for include/asm/Kbuild.asm. The problem
is that the header files will be split or moved one at a time, but each header
file in Kbuild.asm's list applies to all arch headers of that name
Move include/linux/version.h to the include/generated/ header directory.
A later patch will move it to include/uapi/generated/.
This allows us to get rid of the objhdr-y list.

Cool!!!
This certainly provides another data point in favor of running
Remove the objhdr-y export list as it is no longer used. genhdr-y should be

Differentiate the generated UAPI and internal headers during generation such
that the UAPI headers can be installed elsewhere.
A later patch will use this to move the UAPI headers to:
arch/x86/include/generated/uapi/asm/
to make them easier to handle.
A previous patch added a -I for
Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.

The device identifies itself as
0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X
Fusion-MPT SAS (rev 01) Subsystem: NEC Corporation SAS1068

The request for support of this device has been raised on mailinglists
Replace very long constants for EFI variable attributes
with shorter and more convenient names. Also create an
alias for the current longer names so as to not break
compatibility with current API since these constants
