The patch titled Subject: remove recently added perl build requirement has been removed from the -mm tree. Its filename was remove-recently-added-perl-build-requirement.patch This patch was dropped because an alternative patch was merged ------------------------------------------------------ From: Rob Landley <rob@xxxxxxxxxxx> Subject: remove recently added perl build requirement Commit e6023367d779 ("x86, kaslr: Prevent .bss from overlaping initrd") added perl back to the kernel build dependencies in -rc6. Replace those 39 lines of perl with 4 lines of shell script. Note: checkpatch.pl isn't a build dependency, it's a development dependency (like bloat-o-meter being written in python or "make xconfig" needing QT). Those aren't things you need to add to your cross compile environment to produce a binary. Different category of dependency.
