This fixes a build failure on drm-tip. This issue was introduced during
merge of "drm/ttm: replace busy placement with flags v6". For some
reason, the xe_bo.c part of above change is not merged. Manually merge
the missing part to drm_tip

Mhm, I provided this as manual fixup for drm-tip in this rerere commit:

commit afc5797e8c03bed3ec47a34f2bc3cf03fce24411
Author: Christian König <christian.koenig@amd.com>
Date:   Thu Jan 25 10:44:54 2024 +0100

     2024y-01m-25d-09h-44m-07s UTC: drm-tip rerere cache update

     git version 2.34.1


And for me compiling xe in drm-tip worked fine after that. No idea why 
that didn't work for you.

Anyway feel free to add my rb to this patch here if it helps in any way.

Regards,
Christian.

I reverted that rerere cache update and added another one, so now it 
works. Not sure exactly what the difference was, but the resulting patch 
was for the drm-misc-next merge in my case, and It was for 
drm-xe-something in your case.

Hi Thomas,

My patch was based on drm-tip.... because I found drm-tip is broken....

As long as drm-tip can build, I am all good.

Thanks,
Oak

Yes, but drm-tip is rebuilt and force-pushed every time any of the 
merged branches adds a new commit, so any commit needs to land in any of 
the included branches, and when that is not possible because of 
interdependencies, it needs to land in a merge commit, or a separate 
"fixup" to a merge.

All described here:

https://drm.pages.freedesktop.org/maintainer-tools/drm-tip.html#

What was happening in this case was that the "fixup" Christian had added 
somehow didn't work, so I removed it and added a new one. We never apply 
patches directly on drm-tip.

Yeah, I've noticed that this was applied to the drm-xe-something branch 
as well. That's why I reverted and re-applied the patch but dim still 
ended up applying it to drm-xe-something instead of drm-misc-next so I 
thought that this was intentional.

It would be rather nice if somebody can tell me what the heck went wrong 
here so that I don't repeat this mistake.

Thanks,
Christian.

TBH I'm not completely sure. Sometimes those fixups are not recognized 
and applied, which seems to be have been the case here.

But it appears to be important to break the interactive rebuild-tip just 
after the merge that brings in the silent conflict. In this case it was 
drm-misc-next. Sometimes it might also help to hold off commiting until 
drm-misc-next backmerges the recent release series and thus contain all 
code that the commit touches.
