Subject: [PATCH AUTOSEL 5.10 13/17] local64.h: make <asm/local64.h> mandatory

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 87dbc209ea04645fd2351981f09eff5d23f8e2e9 ]

Make <asm-generic/local64.h> mandatory in include/asm-generic/Kbuild and
remove all arch/*/include/asm/local64.h arch-specific files since they
only #include <asm-generic/local64.h>.

This fixes build errors on arch/c6x/ and arch/nios2/ for
block/blk-iocost.c.

Build-tested on 21 of 25 arch-es.  (tools problems on the others)

Yes, we could even rename <asm-generic/local64.h> to
<linux/local64.h> and change all #includes to use
<linux/local64.h> instead.
