#     powerpc/barrier: Avoid collision with clang's __lwsync macro
#     
#     A change in clang 13 results in the __lwsync macro being defined as
#     __builtin_ppc_lwsync, which emits 'lwsync' or 'msync' depending on what
#     the target supports. This breaks the build because of -Werror in
#     arch/powerpc, along with thousands of warnings:

#      #define __lwsync __builtin_ppc_lwsync
#             ^
#      1 error generated.
#     
#     Undefine this macro so that the runtime patching introduced by
#     commit 2d1b2027626d ("powerpc: Fixup lwsync at runtime") continues to
#     work properly with clang and the build no longer breaks.
