96b8936a9e remove __ARCH_WANT_COMPAT_SYS_PTRACE
All architectures now use the generic compat_sys_ptrace, as should every
new architecture that needs 32bit compat (if we'll ever get another).

Remove the now superflous __ARCH_WANT_COMPAT_SYS_PTRACE define, and also
kill a comment about __ARCH_SYS_PTRACE that was added after
__ARCH_SYS_PTRACE was already gone.

211f05a034 input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback
ml_ff_playback() uses spin_(un)lock_bh. However this function is called
with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196.

This is not permitted, and will result in a WARN_ON in the bottom half handling code.
This patch changes this function to just use spin_lock_irqsave() instead, solving
the problem and simplifying the locking logic.

This was reported as entry #106559 in kerneloops.org

56d74dd5f7 tricky one: hisax sections
a) hisax_init_pcmcia() needs to be defined only if we have
   CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared
   __devinit.

b) HiSax_inithardware() can go __init

c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
	checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
   The problem with it is that
	* hisax_cs_setup_card() is __devinit
	* hisax_register() is not
	* hisax_cs_setup_card() is a switch from hell, calling a lot of
	  setup_some_weirdcard() depending on card->typ.  _These_ are also
	  __devinit.

   However, in hisax_register() we have card->typ equal to
   ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
   all that crap, just do nothing and return 2".  So we add a
   trimmed-down callback doing just that and passed to checkcard() by
   hisax_register().  _This_ is non-init (we can stand the impact on
   .text size).

Voila - no section warnings from drivers/isdn

30037818f7 advansys fix on ISA-less configs
The code

        if (shost->dma_channel != NO_ISA_DMA)
                free_dma(shost->dma_channel);

in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to
something other than NO_ISA_DMA under #ifdef CONFIG_ISA).  OTOH, free_dma() is
not guaranteed to be there in absense of CONFIG_ISA.  IOW, driver runs into
undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false
positive.

Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and
dependency on free_dma() disappears for !CONFIG_ISA.

Linus points out that the fix is not complete:

>
> Of course, in _practice_, I don't think gcc ever will (if it decides

So make sure our nr_running value is immutable and cannot change
after we check it for nonzero.

1583715ddb sched, cpusets: fix warning in kernel/cpuset.c
this warning:

  kernel/cpuset.c: In function ‘generate_sched_domains’:
  kernel/cpuset.c:588: warning: ‘ndoms’ may be used uninitialized in this function

triggers because GCC does not recognize that ndoms stays uninitialized
only if doms is NULL - but that flow is covered at the end of
generate_sched_domains().

Help out GCC by initializing this variable to 0. (that's prudent anyway)

Also, this function needs a splitup and code flow simplification:
with 160 lines length it's clearly too long.
