ARM: OMAP2+: move platform-specific asm-offset.h to arch/arm/mach-omap2
<generated/ti-pm-asm-offsets.h> is only generated and included by
arch/arm/mach-omap2/, so it does not need to reside in the globally
visible include/generated/.
I renamed it to arch/arm/mach-omap2/pm-asm-offsets.h since the prefix
'ti-' is just redundant in mach-omap2/.
My main motivation of this change is to avoid the race condition for
the parallel build (-j) when CONFIG_IKHEADERS is enabled.
When it is enabled, all the headers under include/ are archived into
kernel/kheaders_data.tar.xz and exposed in the sysfs.
In the parallel build, we have no idea in which order files are built.
- If ti-pm-asm-offsets.h is built before kheaders_data.tar.xz,
the header will be included in the archive. Probably nobody will
use it, but it is harmless except that it will increase the archive
size needlessly.
- If kheaders_data.tar.xz is built before ti-pm-asm-offsets.h,
the header will not be included in the archive. However, in the next
build, the archive will be re-generated to include the newly-found
ti-pm-asm-offsets.h. This is not nice from the build system point
of view.
- If ti-pm-asm-offsets.h and kheaders_data.tar.xz are built at the
same time, the corrupted header might be included in the archive,
which does not look nice either.
This commit fixes the race.
