This function is called from non-__init context, just like
tegra_gpio_enable()/disable(). Remove the __init annotation to avoid
section mismatch warnings during compile.

Unbanked GPIO IRQ handling code made a copy of just
the irq_chip structure for GPIO IRQ lines which caused
problems after the generic IRQ chip conversion because
there was no valid irq_chip_type structure with the
right "regs" populated. irq_gc_mask_set_bit() was
therefore accessing random addresses.
Fix it by making a copy of irq_chip_type structure
instead. This will ensure sane register offsets.

The present _get_value routine returns the contents of the GPIO Monitor Pin
Status Register(GPMR) starting from the bit whose value is requested to BIT 0
(irrelevant bits are replace by 0).
For e.g. if we request the value of GPIO 6 in the earlier implementation the
value returned is:
BIT6 followed by 6 0's
whereas it should just return BIT6.
This patch addresses the same.

Update gpio.txt based on recent discussions regarding interaction with the
pinctrl subsystem.
Previously, gpio_request() was described as explicitly not performing any
required mux setup operations etc.
Now, gpio_request() is explicitly as explicitly performing any required mux
setup operations where possible. In the case it isn't, platform code is
required to have set up any required muxing or other configuration prior to
gpio_request() being called, in order to maintain the same semantics.
This is achieved by gpiolib drivers calling e.g. pinctrl_request_gpio() in
their .request() operation.

The chip offers the function to detect the current state of output of the GPO
P3 pins. Useful for reading GPIO output state in Linux' GPIO API, e.g. via
sysfs.
Please note that this only reads back the currently programmed output state,
not the actual electrical level in terms of a GPI function. Finally, GPO3 is
still just an output.

While both level- and edge-triggered GPIOs are capable of generating
interrupts, only edge-triggered GPIOs are capable of generating a
module-level wakeup to the PRCM (c.f. 34xx NDA TRM section 25.5.3.2.)
In order to ensure that devices using level-triggered GPIOs as
interrupts can also cause wakeups (e.g. from idle), this patch enables
edge-triggering for wakeup-enabled, level-triggered GPIOs when a GPIO
bank is runtime-suspended (which also happens during idle.)
This fixes a problem found in GPMC-connected network cards with GPIO
interrupts (e.g. smsc911x on Zoom3, Overo, ...) where network booting
with NFSroot was very slow since the GPIO IRQs used by the NIC were
not generating PRCM wakeups, and thus not waking the system from idle.
NOTE: until v3.3, this boot-time problem was somewhat masked because
the UART init prevented WFI during boot until the full serial driver
was available. Preventing WFI allowed regular GPIO interrupts to fire
and this problem was not seen. After the UART runtime PM cleanups, we
no longer avoid WFI during boot, so GPIO IRQs that were not causing
wakeups resulted in very slow IRQ response times.
Tested on platforms using level-triggered GPIOs for network IRQs using
the SMSC911x NIC: 3530/Overo and 3630/Zoom3.

Current code has put_ioctx() called asynchronously from aio_fput_routine();
that's done *after* we have killed the request that used to pin ioctx,
so there's nothing to stop io_destroy() waiting in wait_for_all_aios()
from progressing. As the result, we can end up with async call of
put_ioctx() being the last one and possibly happening during exit_mmap()
or elf_core_dump(), neither of which expects stray munmap() being done
to them...
We do need to prevent _freeing_ ioctx until aio_fput_routine() is done
with that, but that's all we care about - neither io_destroy() nor
exit_aio() will progress past wait_for_all_aios() until aio_fput_routine()
does really_put_req(), so the ioctx teardown won't be done until then
and we don't care about the contents of ioctx past that point.
Since actual freeing of these suckers is RCU-delayed, we don't need to
bump ioctx refcount when request goes into list for async removal.
All we need is rcu_read_lock held just over the ->ctx_lock-protected
area in aio_fput_routine().

Have ioctx_alloc() return an extra reference, so that caller would drop it
on success and not bother with re-grabbing it on failure exit. The current
code is obviously broken - io_destroy() from another thread that managed
to guess the address io_setup() would've returned would free ioctx right
under us; gets especially interesting if aio_context_t * we pass to
io_setup() points to PROT_READ mapping, so put_user() fails and we end
up doing io_destroy() on kioctx another thread has just got freed...

Respectfully revert commit e6ca7b89dc76 "memcg: fix mapcount check
in move charge code for anonymous page" for the 3.3 release, so that
it behaves exactly like releases 2.6.35 through 3.2 in this respect.
Horiguchi-san's commit is correct in itself, 1 makes much more sense
than 2 in that check; but it does not go far enough - swapcount
should be considered too - if we really want such a check at all.
We appear to have reached agreement now, and expect that 3.4 will
remove the mapcount check, but had better not make 3.3 different.

Commit f0fbf0abc093 ("x86: integrate delay functions") converted
delay_tsc() into a random delay generator for 64 bit. The reason is
that it merged the mostly identical versions of delay_32.c and
delay_64.c. Though the subtle difference of the result was:
static void delay_tsc(unsigned long loops)
{
- unsigned bclock, now;
+ unsigned long bclock, now;
Now the function uses rdtscl() which returns the lower 32bit of the
TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64
bit this fails when the lower 32bit are close to wrap around when
bclock is read, because the following check
if ((now - bclock) >= loops)
break;
evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0
because the unsigned long (now - bclock) of these values results in
0xffffffff00000001 which is definitely larger than the loops
value. That explains Tvortkos observation:
"Because I am seeing udelay(500) (_occasionally_) being short, and
that by delaying for some duration between 0us (yep) and 491us."
Make those variables explicitely u32 again, so this works for both 32
and 64 bit.

defer_bh() takes the lock which is hold during unlink_urbs(). The safe
walk suggest that the skb will be removed from the list and this is done

We initialize the routing metrics with the values cached on the
inetpeer in rt_init_metrics(). So if we have the metrics cached on the
inetpeer, we ignore the user configured fib_metrics.
To fix this issue, we replace the old tree with a fresh initialized
inet_peer_base. The old tree is removed later with a delayed work queue.

The 'rebuild' parameter is used to rebuild individual devices in an
array (e.g. resynchronize a RAID1 device or recalculate a parity device
in higher RAID). The MD_CHANGE_DEVS flag must be set when this
parameter is given in order to write out the superblocks and make the
change take immediate effect. The code that handles new devices in
super_load already sets MD_CHANGE_DEVS and 'FirstUse'. (The 'FirstUse'
flag was being set as a special case for rebuilds in
super_init_validation.)
Add a condition for rebuilds in super_load to take care of both flags
without the special case in 'super_init_validation'.
