So originally 0-day build found that commit a10a1701 (mm, x86: add support for PUD-sized transparent hugepages) is breaking 32bit x86 UP config because native_pud_clear() was missing to satisfy arch/x86/include/asm/pgtable.h. I added a dummy function to satisfy that with commit e4decc90 (mm,x86: native_pud_clear missing on i386 build). However in the process of doing that, I broke the 32bit x86 SMP config that was working before. > >> Fix: e4decc90 mm,x86: native_pud_clear missing on i386 build > > Which tree is that in, btw? > linux-next-20170214 I believe -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
