Happy fixing! ;-)
Thanks to the linux-next team for providing the build service.

Well....
- /kisskb/src/fs/xfs/xfs_buf.h: error: initializer element is not constant: => 46:23
Looking at:
http://kisskb.ellerman.id.au/kisskb/buildresult/14714961/
The build error is:
/kisskb/src/fs/xfs/./xfs_trace.h:432:2: note: in expansion of macro 'TP_printk' TP_printk("dev %d:%d daddr 0x%llx bbcount 0x%x hold %d pincount %d " ^ /kisskb/src/fs/xfs/./xfs_trace.h:440:5: note: in expansion of macro '__print_flags' __print_flags(__entry->flags, "|", XFS_BUF_FLAGS), ^ /kisskb/src/fs/xfs/xfs_buf.h:67:4: note: in expansion of macro 'XBF_UNMAPPED' { XBF_UNMAPPED, "UNMAPPED" } ^ /kisskb/src/fs/xfs/./xfs_trace.h:440:40: note: in expansion of macro 'XFS_BUF_FLAGS' __print_flags(__entry->flags, "|", XFS_BUF_FLAGS), ^ /kisskb/src/fs/xfs/./xfs_trace.h: In function 'trace_raw_output_xfs_buf_flags_class': /kisskb/src/fs/xfs/xfs_buf.h:46:23: error: initializer element is not constant #define XBF_UNMAPPED (1 << 31)/* do not map the buffer */
This doesn't make a whole lotta sense to me. It's blown up in a tracepoint macro in XFS that was not changed at all in 5.18-rc1, nor was any of the surrounding XFS code or contexts. Perhaps something outside XFS changed to cause this on these platforms?
Can you bisect this, please?
Cheers,
Dave.

After v5.17 there were two commits to brcmfmac/sdio.c:
$ git log --oneline v5.17.. drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c ed26edf7bfd9 brcmfmac: Add BCM43454/6 support 6d766d8cb505 brcmfmac: pcie: Declare missing firmware files in pcie.c
I can't see how either of them could cause this warning. Could something else cause this or am I missing something?

Doh, I should not have reduced the CC list in the xfs subthread...
The builds above are all gcc-5 builds, so they are affected by the same issue as XFS: unsigned constants that don't fit in int are lacking a "U" suffix.
I assume Arnd's patch for drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c fixes this? https://lore.kernel.org/all/CAK8P3a0wRiS03imdXk2WbGONkSSczEGdE-ue5ubF6UyyDE9...
