mn10300 (v3.10, v3.14):
kernel/uid16.c:19:1: error: unknown type name 'old_uid_t'
kernel/uid16.c:19:1: error: unknown type name 'old_gid_t'
ipc/util.c:609:2: error: 'old_uid_t' undeclared
and other similar errors. Requires c86576ea114a ("mn10300: Select CONFIG_HAVE_UID16
to fix build failure"). Results in minor easy to resolve conflict in v3.10.y (I didn't
check v3.14.y). Let me know if you need a backport.
4.1 and 4.3 are also affected by this problem.

arm64 (4.1, 4.3):
allmodconfig core dumps (oops). I'll need to look into that one.
Two patches are culprits here:
- 'recordmcount: arm64: Replace the ignored mcount call into nop' causes the crash.
It is not the C compiler. Maybe some other patch to recordmcount is missing.
This bug is due the endianness mix at-least in my build setup and commit
c84da8b9ad37 ("recordmcount: Fix endianness handling bug for
nop_mcount") seems to fix it for me.
It's already marked for stable and I see that there are quite a few
patches queued for stable in scripts/recordmcount.[ch]. But I see Greg
has already pointed this out in the NOTE in his initial "[PATCH 4.1
000/127] 4.1.17-stable review" email.
- 'arm64: mm: use correct mapping granularity under DEBUG_RODATA' uses SWAPPER_BLOCK_SIZE
which is not defined in 4.3. This causes a build failure in 4.3 after reverting the above.
I didn't check 4.1.
Ardb already posted a fix for this [1]
Ok, as I have no idea here, and don't have an arm64 system to do
anything with (i.e. test), I'll just leave this alone until someone who
does care about the architecture comes along with a fix :)
