The arm64 asm/cmpxchg.h includes linux/mmdebug.h but doesn't so far as I can tell actually use anything from it. Removing the inclusion reduces spurious header dependency rebuilds and also avoids issues with recursive inclusions of headers causing build breaks due to attempts to use things before they are defined if linux/mmdebug.h starts pulling in more low level headers.
Such errors have happened in -next recently, for example:

Today's -next fails to build most arm64 configs with some rather spectacular errors below introduced by 02598e94ed5a78 (mm, printk: introduce new format string for flags) from Andrew's tree. These in turn stem from the fact that we introduce an inclusion of linux/tracepoint.h into linux/mmdebug.h which through a chain of nested inclusions means that we end up attempting to use definitions from headers before they have finished including. For example:
arm64-allnoconfig ../include/linux/wait.h:1217:2: error: implicit declaration of function 'atomic_read' [-Werror=implicit-function-declaration]
is a result of:
In file included from include/linux/completion.h:11:0, from include/linux/rcupdate.h:43, from include/linux/tracepoint.h:19, from include/linux/mmdebug.h:6, from ./arch/arm64/include/asm/cmpxchg.h:22, from ./arch/arm64/include/asm/atomic.h:41, from include/linux/atomic.h:4, from include/linux/spinlock.h:406, from include/linux/seqlock.h:35, from include/linux/time.h:5, from include/uapi/linux/timex.h:56, from include/linux/timex.h:56, from include/linux/sched.h:19, from arch/arm64/kernel/asm-offsets.c:21: include/linux/wait.h: In function 'wait_on_atomic_t': include/linux/wait.h:1218:2: error: implicit declaration of function 'atomic_read' [-Werror=implicit-function-declaration] if (atomic_read(val) == 0)
where atomic_read() will be defined in atomic.h which is part of the inclusion chain above but hasn't yet parsed far enough to actually define anything. This is all a bit of a horrific mess the root cause of which appears to be that arm64 is unusual in including linux/mmdebug.h in asm/cmpxchg.h which triggers the mess. There doesn't seem to be any reason for this inclusion, I've just sent a patch removing it. It'd be good to get this into -next as a matter of urgency.

where atomic_read() will be defined in atomic.h which is part of the inclusion chain above but hasn't yet parsed far enough to actually define anything.

I'll pick up your fix into the arm64 for-next/core branch.
Cheers,

Thanks.
Further complexicating the include tree is something we don't need. I'll try moving the offending declarations into mm/internal.h, see how that goes.
Including ../mm/internal.h into lib/vsprintf.c is a bit grubby, but I guess it makes sense - vsprintf is poking about in mm internals, so it gets to include mm's internal.h.
Vlastimil, the patch is rather bloaty - it adds 1.2k for something which few people will use. I wonder if it should be conditioned by CONFIG_DEBUG_VM.

Yeah that works too, thanks.

OK.

Hmm, but one of the benefits is that we get e.g. the gfp flags translated in oom and alloc failure reports that users submit, and CONFIG_DEBUG_VM is not enabled by default. So the conditioning should be based on some option that people explicitly enable to make their kernels smaller knowing it's a tradeoff for functionality/convenience.
