The patch titled
Subject: lib: move sort self-test into a separate file
has been removed from the -mm tree. Its filename was
lib-add-config_test_sort-to-enable-self-test-of-sort-fix.patch
This patch was dropped because it was folded into lib-add-config_test_sort-to-enable-self-test-of-sort.patch
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: lib: move sort self-test into a separate file
The lib/sort.c file gets included in the EFI stub for use outside of the
kernel address space, which now fails due to the addition of a
module_init() function:
00000000 R_ARM_ABS32 test_sort_init
drivers/firmware/efi/libstub/lib-sort.stub.o: absolute symbol references not allowed in the EFI stub
drivers/firmware/efi/libstub/Makefile:69: recipe for target 'drivers/firmware/efi/libstub/lib-sort.stub.o' failed
Other library tests live in a separate file, so doing the same here
is an easy way to avoid the problem.
Fixes: akpm-current ("lib: add CONFIG_TEST_SORT to enable self-test of sort()")
