Merge branch 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers
Pull UAPI disintegration fixes from David Howells: "There are three main parts: (1) I found I needed some more fixups in the wake of testing Arm64 (some asm/unistd.h files had weird guards that caused problems - mostly in arches for which I don't have a compiler) and some __KERNEL__ splitting needed to take place in Arm64. (2) I found that c6x was missing some __KERNEL__ guards in its asm/signal.h. Mark Salter pointed me at a tree with a patch to remove that file entirely and use the asm-generic variant instead. (3) Lastly, m68k turned out to have a header installation problem due to it lacking a kvm_para.h file. The conditional installation bits for linux/kvm_para.h, linux/kvm.h and linux/a.out.h weren't very well specified - and didn't work if an arch didn't have the asm/ version of that file, but there *was* an asm-generic/ version. It seems the "ifneq $((wildcard ...),)" for each of those three headers in include/kernel/Kbuild is invoked twice during header installation, and the second time it matches on the just installed asm-generic/kvm_para.h file and thus incorrectly installs linux/kvm_para.h as well. Most arches actually have an asm/kvm_para.h, so this wasn't detectable in those." * 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k) c6x: remove c6x signal.h UAPI: Split compound conditionals containing __KERNEL__ in Arm64 UAPI: Fix the guards on various asm/unistd.h files c6x: make dsk6455 the default config
