Mark Brown
maintainerHi all,
During the final builds today's linux-next build (powerpc pseries_le_defconfig) failed like this:
/tmp/next/build/mm/hugetlb.c: In function 'hugetlb_unshare_pmds':/tmp/next/build/mm/hugetlb.c:7282:17: error: implicit declaration of function '__huge_pmd_unshare'; did you mean 'huge_pmd_unshare'? [-Wimplicit-function-declaration]
7282 | __huge_pmd_unshare(&tlb, vma, address, ptep, take_locks);
| ^~~~~~~~~~~~~~~~~~
| huge_pmd_unsharemake[4]: *** [/tmp/next/build/scripts/Makefile.build:289
Caused by commit
2bb8fe16f7bf4 (mm/hugetlb: avoid false positive lockdep assertion)
I have reverted this commit for today.

I removed this from mm.git on May 15, but I cannot find the email which prompted me to do that :(
Oh well, I assume Lorenzo will send a new version, thanks.

I sent a fix-patch for this, but will send a respin today if that's easier.
This is a trivial 'forgot to add a stub for a certain config' thing.
Cheers, Lorenzo
