2.6.12-rc3-mm1 fails to compile for an arm pxa sharp zaurus kernel:
LD .tmp_vmlinux1
fs/built-in.o(.text+0x39110): In function `smaps_pte_range':
task_mmc.c: undefined reference to `clean_pmd_entry'
make: *** [.tmp_vmlinux1] Error 1
Adding #include <asm/tlbflush.h> to fs/proc/task_mmu.c "fixes" this although
I doubt that's the correct thing to do.
The config I'm using is at http://www.rpsys.net/openzaurus/defconfig-c7x0
if needed.
I'm also seeing problems with CompactFlash cards (I also saw this with
2.6.12-rc2-mm3, other versions are untested). I'm using pcmcia-cs (not
pcmciautils) but that shouldn't be a problem as I understand things. The
card mounts fine as the machine boots and I can access it fine. Trying to
eject the card causes problems:
Normally I can execute "cardctl eject" and then remove the card. I trigger
the oops below however I try to eject the card under this kernel though.
(Note: I never physically remove it here although that will also trigger an
oops). I suspect this is a further problem with ide-cs (which nobody has
both the knowledge and time to fix) although I'm open to advice as to where
the fault lies:
