linux-next: triage for May 7, 2012

Lots of new fires burning today, let me try to summarize.

Looks like the "old" mmc fails got replaced by new ones on some
different boards. I've reported the new fail on arm-kernel with
the cause of the fail.
[ http://marc.info/?l=linux-arm-kernel&m=133642820330185&w=2 ]

Something evil vandalized all mips builds. At a glance it looks
like a kbuild thing -- it fails with:
LD init/built-in.o
KSYM .tmp_kallsyms1.o
<command-line>:0:1: error: macro names must be identifiers

The itanic blew up with some new kooky ld error I've not seen
before ("ia64-linux-ld: .tmp_kallsyms1.o: linking constant-gp
files with non-constant-gp files)

For arch=cris,m68k -- some new tty related fallout appeared.
Geert has a m68k patch posted 3pm EST today.

The parisc blew up on a basic gcc config option (WTF?)

I've triaged and fixed the ppc mpc85xx_defconfig fail; it is
in my linux-next feed temporarily.

The kvm export annoyance [sparc/parisc,etc] continues to linger.

The kallsyms nonsense on ARM continues to muddy the waters on the
pass/fail triage as it shifts around from board to board. :(


New breakage since last report:
drivers/mmc/host/mmci.c: implicit decl mmci_dt_populate_generic_pdata
<command-line>:0:1: error: macro names must be identifiers
drivers/tty/amiserial.c: too few args to function 'tty_unlock'
ld: unrecognized option '-print-libgcc-file-name`
tty/serial/crisv10.c: blows up with two new errors.

Randconfig fails that may or may not be new (by their very nature):
i386: drivers/gpu/drm/radeon/radeon_state.o and
arch/x86/include/asm/uaccess_32.h:211:26: error: call to
'copy_from_user_overflow' declared with attribute error:
copy_from_user() buffer size is not provably correct
[ http://kisskb.ellerman.id.au/kisskb/buildresult/6271958/ ]

Builds that are fixed since last report:
powerpc:ppc40x_defconfig (ppc4xx_msi.c:right shift >= width of type)
s390:allyesconfig,allmodconfig (via ARM emif kconfig dependency)


Note1: The randconfig fails are only listed once and not tracked
in the below listing.

Note2: Build fails that are perpetual and/or unlikely to ever
get fixed are not tracked here.

Note3: Issues that Stephen finds and reverts/avoids before kicking
off the all-arch/all-config builds are also not tracked here.

Note4: I'm also not tracking the kallsyms extra pass on ARM on
a per board basis anymore. It has nothing to do with the board.
Why? See: http://marc.info/?l=linux-next&m=133267456809502
