Using "arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.7.3-12ubuntu1) 4.7.3", here's the error when building for multi_v7_defconfig (full log available[2]): ../mm/migrate.c: In function 'migrate_pages': ../mm/migrate.c:1148:1: internal compiler error: in push_minipool_fix, at config/arm/arm.c:13101 Please submit a full bug report, with preprocessed source if appropriate.

Preprocessed source stored into /tmp/ccO1Nz1m.out file, please attach this to your bugreport. make[2]: *** [mm/migrate.o] Error 1 make[2]: Target `__build' not remade because of errors. make[1]: *** [mm] Error 2 build bisect points to commit 21f992084aeb[3], but that doesn't revert cleanly so I haven't got any further than that yet.

Shutemov <kirill.shutemov@xxxxxxxxxxxxxxx> Date: Wed Mar 25 13:02:28 2015 +1100 page-flags: define behavior of FS/IO-related flags on compound pages It seems we don't have compound page on FS/IO path currently. Use NO_COMPOUND to catch if we have. The odd exception is PG_dirty: sound uses compound pages and maps them with PTEs. NO_COMPOUND triggers VM_BUG_ON() in set_page_dirty() on handling shared fault. Let's use HEAD for PG_dirty. Signed-off-by: Kirill A.
