If anyone has any objections, please let me know. ------------------ From: Nathan Chancellor [ Upstream commit 87c4e1459e80bf65066f864c762ef4dc932fad4b ] After commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper flags and language target"), which updated as-instr to use the 'assembler-with-cpp' language option, the Kbuild version of as-instr always fails internally for arch/arm with : fatal error: asm/unified.h: No such file or directory compilation terminated. because '-include' flags are now taken into account by the compiler driver and as-instr does not have '$(LINUXINCLUDE)', so unified.h is not found. This went unnoticed at the time of the Kbuild change because the last use of as-instr in Kbuild that arch/arm could reach was removed in 5.7 by commit 541ad0150ca4 ("arm: Remove 32bit KVM host support") but a stable backport of the Kbuild change to before that point exposed this potential issue if one were to be reintroduced. Follow the general pattern of '-include' paths throughout the tree and make unified.h absolute using '$(srctree)' to ensure KBUILD_AFLAGS can be used independently.
