Kbuild: arch: look for generated headers in obtree
There are very few files that need add an -I$(obj) gcc for the preprocessor or the assembler. For C files, we add always these for both the objtree and srctree, but for the other ones we require the Makefile to add them, and Kbuild then adds it for both trees. As a preparation for changing the meaning of the -I$(obj) directive to only refer to the srctree, this changes the two instances in arch/x86 to use an explictit $(objtree) prefix where needed, otherwise we won't find the headers any more, as reported by the kbuild 0day builder. arch/x86/realmode/rm/realmode.lds.S:75:20: fatal error: pasyms.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Marek <mmarek@suse.com>
