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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
