Merge branch 'disintegrate-asm-generic' of git://git.infradead.org/users/dhowells/linux-headers into asm-generic

Patches from David Howells <dhowells@redhat.com>:

This is to complete part of the UAPI disintegration for which the
preparatory patches were pulled recently.

Note that there are some fixup patches which are at the base of the
branch aimed at you, plus all arches get the asm-generic branch merged in too.

* 'disintegrate-asm-generic' of git://git.infradead.org/users/dhowells/linux-headers:
  UAPI: (Scripted) Disintegrate include/asm-generic
  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

- * Noteworthy Issues
- * -----------------
- *
- * This driver is complicated by the fact that this is a 16-bit chip
- * and, on at least one platform (ceiva), we can only do 16-bit reads
- * and writes to the framebuffer.  We hide this from user space
- * except in the case of mmap().
- *
- *
- * To Do
- * -----
- *
- * - Test 8-bit pseudocolor mode
- * - Allow setting bpp, virtual resolution
- * - Implement horizontal panning
- * - (maybe) Implement hardware cursor
