The patch titled
Subject: ubsan: enable for all*config builds
has been removed from the -mm tree. Its filename was
ubsan-enable-for-allconfig-builds.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Kees Cook <keescook@chromium.org>
Subject: ubsan: enable for all*config builds
With UBSAN_OBJECT_SIZE disabled for GCC, only UBSAN_ALIGNMENT remained a
noisy UBSAN option. Disable it for COMPILE_TEST so the rest of UBSAN can
be used for full all*config builds or other large combinations.
[sfr@canb.auug.org.au: add .data..Lubsan_data*/.data..Lubsan_type* sections explicitly]
