commit 0678220defe2b5183a4e33ceeb58780cccce9ac5 Author: Stewart Hildebrand <stewart.hildebrand@xxxxxxx> AuthorDate: Fri Apr 14 14:57:12 2023 -0400 Commit: Julien Grall <jgrall@xxxxxxxxxx> CommitDate: Wed Apr 19 19:26:28 2023 +0100 xen/arm: mark __guest_cmpxchg always_inline When building the hypervisor with -Og, we run into a __bad_cmpxchg link error: aarch64-none-linux-gnu-ld: prelink.o: in function `__int_cmpxchg': .../xen/./arch/arm/include/asm/arm64/cmpxchg.h:117: undefined reference to `__bad_cmpxchg' aarch64-none-linux-gnu-ld: .../xen/./arch/arm/include/asm/arm64/cmpxchg.h:117: undefined reference to `__bad_cmpxchg' aarch64-none-linux-gnu-ld: ./.xen-syms.0: hidden symbol `__bad_cmpxchg' isn't defined aarch64-none-linux-gnu-ld: final link failed: bad value This is due to the function __guest_cmpxchg not being inlined in the -Og build with gcc 12. Fix this by marking __guest_cmpxchg always_inline.
