linux-next: triage for April 10, 2012

I didn't do a report on Friday for Thursday's tree, however there were four new breakages at the end of last week. I did a triage on them and sent notifications to those maintainers. (and cc'd linux-next). DaveM checked in fixes for blackfin eth and gianfar eth as soon as I reported them, leaving only the regmap_debugfs_init bug and and the GPLV2 vs GPLv2 typo carried forward into this week's report (listed below).

We've finally got an sh tree inserted into linux-next, so a a whole bunch of sh4 builds are now green again. Probably makes sense to go through and triage the remaining failures as "new". I have not done that yet here today since there are about 20 or so.

------------

New breakage since last report:
i386:allmodconfig:
(modpost: GPL-incompat rc5t583-regulator uses GPL-only symbol)
ARM/MIPS:magician_defconfig,omap1_defconfig,ip27_defconfig
(regmap.c: too few arg to 'regmap_debugfs_init')
ARM:eseries_pxa_defconfig,em_x270_defconfig,imx_v4_v5_defconfig
(sound/soc/codecs/wm9712.c: error: 'runtime' undeclared)
s390/sparc:allmodconfig,allyesconfig
(wiznet Kconfig fallout, fixed by DaveM already)
ARM:cam60_defconfig (kallsyms, ignore it).

Randconfig fails that may or may not be new (by their very nature):

	i386: fs/binfmt_misc.c (copy_from_user() is not provably correct)
		http://kisskb.ellerman.id.au/kisskb/buildresult/6087086/
	powerpc: kernel/built-in.o: undefined ref `perf_ftrace_event_register'
		http://kisskb.ellerman.id.au/kisskb/buildresult/6087164/
		Fix: https://lkml.org/lkml/2012/3/14/304

Builds that are fixed since last report:
ia64:defconfig
sh4:about 1/2 of all builds.

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

I'm also not tracking the kallsyms extra pass stuff 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

that log file doesn't say anything about "BFD_RELOC_BFIN_10"

it does show the old L1 data overflow though ...

on a side note, the warning:
arch/blackfin/mm/init.c:79:9: warning: array subscript is above array bounds [-Warray-bounds]
is a bad thing, but i've just pushed a fix for that ... -mike

Thanks Mike, I'll fix the stale link. Here is a RELOC_BFIN_10 fail:

http://kisskb.ellerman.id.au/kisskb/buildresult/6087324/

Looks like I should go over the bfin fails and check each one, since they are somewhat unique -- e.g.

arch/blackfin/mach-bf537/boards/dnp5370.c:392:17: error:
'bfin_spi_board_info' undeclared (first use in this function)

in DNP5370_defconfig

and

arch/blackfin/mach-bf533/boards/ip0x.c:299:26: error:
'bfin_spi_board_info' undeclared (first use in this function)

in IP0X_defconfig

http://kisskb.ellerman.id.au/kisskb/buildresult/6087345/

are not related to the RELOC_BFIN_10

hrm, i'm not seeing that here, but i'm using binutils-2.21. we prob should file a bug for the Blackfin toolchain guys to investigate.

what version of binutils are you using ?

blah, looks like something got renamed, but not all the way

commit 7d157fb02bc3f4dc74e6830725864ba501d92da7
blackfin: config: update macro SPI_BFIN in board file

that renamed SPI_BFIN to SPI_BFIN5XX in the board files

but the commit in drivers/spi/ hasn't been merged yet, so it's still SPI_BFIN there
-mike

Hi Mike,

$ /opt/cross/gcc-4.6-nolibc/bfin-uclinux/bin/bfin-uclinux-ld --version
GNU ld (GNU Binutils) 2.22

This is a cross toolchain hosted in PowerPC.
