It's a day delayed - not because of any particular development issues,

there now, and things have stayed reasonably calm. I really hope that
implies that 3.19 is looking good, but it's equally likely that it's
just that people are still recovering from the holiday season.
I'm consistently getting an out of memory killer triggered when
compiling the kernel (make -j 16 -s) on a 16 core ARM64 system
with 16 GB of memory. This doesn't happen when running a 3.18
kernel.
I'm going to start bisecting the failure now, but here's the crash
log in case someone can see something obvious in it.
Can you disable (transparent) huge pages? I don't have any better at the
moment suggestion apart from bisecting.
I didn't have transparent huge pages on. Turning off hugetblfs didn't
change anything. Turning off 64K pages isn't an option because of
firmware constraints.
What constraints are these? I thought they could only happen the other
way around (4K to 64K).
I was confused. I can turn off 64K pages with only minor loss of
functionality (network MAC address gets corrupted; I can work around
for testing).
With 4K pages, the oom killer doesn't trigger during `make -j 16 -s`
on a fresh kernel. Thanks for the suggestion. I'm not sure what to do
about that, though.
