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.

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).

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.

All noise since we don't have CPU hotplug there. However, they

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

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.

If there is more than one FireWire controller present, dummy_zero_addr
and dummy_max_addr were added multiple times to different lists, thus
corrupting the lists. Fix this by allocating them dynamically per host
instead of just once globally.
(Perhaps a better address space allocation algorithm could rid us of the
two dummy address spaces.)
