Subjectlinux-next: triage for May 10, 2012
This encompasses breakage appearing in the last two trees.

An NFS commit broke ARM, sh4 and or32. (redef 'inode_dio_wait')

An ARM dma commit broke at least four ARM boards.

I tracked down the source of all the mips fails giving this msg:
<command-line>:0:1: error: macro names must be identifiers
to a kbuild thing and a fix should be in shortly (May11?).

I briefly looked at the kvm kernheader export annoyance [sparc/parisc,etc]
and it seems also some kind of kbuild bug -- the headers from asm/generic
are not exported (you can see the same thing with the a.out header).

More details and/or other new dain bramage as listed below.

---------------------
New breakage since last report:
ARM:badge4_defconfig,jornada720_defconfig,neponset_defconfig,cm_x2xx_defconfig
arch/arm/common/dmabounce.c: 'generic_dma_map_sg' undeclared

or32:or1ksim_defconfig
sh4:kfr2r09-romimage_defconfig
ARM:xcep_defconfig,marzen_defconfig (bisected & reported, nfs tree)
fs/inode.c:1777:6: error: redefinition of 'inode_dio_wait'

ARM:at91x40_defconfig
arch/arm/mm/dma-mapping.c: 'pgprot_kernel' undeclared

frv:defconfig
kernel/fork.c: static decl 'alloc_task_struct_node' follows non-static

i386:allmodconfig
input/misc/twl6040-vibra.c: implicit decl 'of_property_read_u32
(reported on linux-next ; needs a Kbuild arch dependency)

i386:allnoconfig
perf_event_amd.c:(.text+0xc0b0): undefined reference to `get_ibs_caps'

powerpc:allmodconfig
ERROR: ".of_mdio_find_bus" [phy/mdio-mux.ko] undefined!

sh4:edosk7705_defconfig
kernel/printk.c:1423: 'LOG_LINE_MAX' undeclared

Randconfig fails that may or may not be new (by their very nature):
i386: tps6586x.c: undefined reference to `of_regulator_match'

Builds that are fixed since last report:
ARM:versatile_defconfig,realview_defconfig,realview-smp_defconfig,
u300_defconfig,vexpress_defconfig
(implicit mmci_dt_populate_generic_pdata)

ARM:sam9_l9260_defconfig (usb/gadget/at91_udc.c 'struct at91_ep' has
no member named 'desc')

cris:etrax-100lx_defconfig
tty/serial/crisv10.c: blows up with two new errors.

m68k:defconfig
drivers/tty/amiserial.c: too few args to function 'tty_unlock'

----------------------
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.
