linux-next: triage for March 31, 2012

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This represents the state of the builds as of Friday, since there
are no weekend linux-next builds.  This is still the 3.4 content.

Lots of breakage to report.  Most of it appears to be caused by
the asm/system.h split up going directly into Linus' tree without
any soak in linux-next.  Lets hope we can avoid this in the future.

I'm not going to list all the fails individually because there are
simply too many.  I'll try and do an arch overview and capture
what has been fixed already and what may remain as unfixed.

Note that "fixed" does not imply it made it into 3.4-rc1; I've
not yet checked what made it there.  But since we now have 3.4-rc1
I'm assuming that linux-next will move onto the 3.5 content, and
so we'll be largely changing context with these triage reports,
and this will represent the last 3.4 based status report.

Of course if breakage is due to mainline commits, please work
to get those in the pending 3.4-rcN (N>1) releases.  I think
the system.h fallout definitely falls into this category.

That said, the asm/system.h breakage that _should_ be fixed:

   ARM: ~10 fails. Olof has run all the defconfigs, and I think fixed them all

	http://lists.arm.linux.org.uk/lurker/message/20120330.232025.982eba3a.en.html

   SPARC: SamR/DaveM have already got the fixes to Linus
	http://marc.info/?l=linux-sparc&m=133315678827041&w=2

   S390: Should be fixed by Heiko
	http://marc.info/?l=linux-s390&m=133311833911171&w=2

The asm/system.h breakage that is possibly not fixed:

   alpha: include/linux/llist.h: asm/cmpxchg.h: No such file or directory
	http://kisskb.ellerman.id.au/kisskb/buildresult/6000253/

   sh4: arch/sh/kernel/cpu/shmobile/pm.c: implicit declaration of 'set_bl_bit'

   sh4: arch/sh/mm/flush-sh4.c implicit declaration of 'register_align' 
	http://kisskb.ellerman.id.au/kisskb/buildresult/6000183/

   MIPS: system.h breakup wasn't tested on master with bug.h change.
	http://kisskb.ellerman.id.au/kisskb/buildresult/6000165/

 ==============================================
	
New breakage since last report:
	See above system.h chaos.

Randconfig fails that may or may not be new (by their very nature):
	powerpc: mpc512x_shared.c: parameter 1 ('port') has incomplete type
		http://kisskb.ellerman.id.au/kisskb/buildresult/6000263/

Builds that are fixed since last report:
	sh4: several configs that were failing on the fls thing that
	originated with DavidH's 1st commit are now passing, but the
	majority of sh4 still fail with the new issues listed above.

	bfin: all builds with the "L1 data A overflow" issue are fixed,
	but conveniently they were also broken via __xchg issue above.

The following have fixes posted for quite some time now, but the fixes
haven't yet been integrated.  Please have a look at these, as it would
be nice to have them in tree for rc2 as build regression fixes.
	ARM:magician_defconfig
	ARM:collie_defconfig
	ARM:iop32x_defconfig,iop33x_defconfig
	ARM:em_x270_defconfig
	AVR32:defconfig


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