commit 8de3afc0b402bc17f65093a53e5870862707a8c7
Author: Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>

xen: move BUG_ON(), WARN_ON(), ASSERT(), ASSERT_UNREACHABLE() to xen/bug.h
Move the macros mentioned in the commit subject to their appropriate
locations.
Additionally, eliminate the dependency of xen/lib.h from xen/bug.h and
include "xen/bug.h" in files where xen/bug.h macros are utilized.
Most of the changes were made because a file requires macros from xen/bug.h,
except for some files for Arm which require definitions of BUG_OPCODE,
BUG_INSTR, BUG_FN_REG.
xen/lib.h was added to list-sort.c ( otherwise compilation errors related
to {d}printk occur during compilation of list-sort.c. ) as xen/lib.h was
removed from xen/list.h. Since nothing in xen/list.h depends on xen/lib.h
functionality and only xen/bug.h is needed.
cpufeature.h requires the inclusion of <xen/cache.h>;
otherwise, the following error will occur:
ld: common/monitor.o:/build/xen/./arch/x86/include/asm/cpufeature.h:41:
multiple definitions of `__cacheline_aligned';
