two reasons:
1. GPIO namings and their mode definitions are conceptually not part
of the PXA register definitions2. this is actually a temporary move in the transition of PXA2xx to
use MFP-alike APIs (as what PXA3xx is now doing), so that legacy
code will still work and new code can be added in step by stepSigned-off-by: eric miao

MFP configurations after resume should be done before the GPIO registers
are restored. Move the mfp sysdev registeration to the same place where
GPIO and IRQ sysdev(s) are registered to better control the order.Signed-off-by: eric miao

The main issue here is that pxa3xx does not have GAFRx registers,
access directly to these registers should be avoided for pxa3xx:1. introduce __gpio_is_occupied() to indicate the GAFRx and GPDRx
registers are already configured on pxa{25x,27x} while returns
0 always on pxa3xx2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign-
ment of GPDRx, the side effect of this change is that the pin
_must_ be configured before use, pxa_gpio_irq_type() will not
change the pin to GPIO, as this restriction is sane, esp. with
the new MFP frameworkSigned-off-by: eric miao

To further clean up the GPIO and IRQ structure:
1. pxa_init_irq_gpio() and pxa_init_gpio() combines into a single
function pxa_init_gpio()2. assignment of set_wake merged into pxa_init_{irq,gpio}() as
an argumentSigned-off-by: eric miao

This makes the code better organized and simplified a bit. The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable. The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0)."struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.Signed-off-by: eric miao

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The
BIOS reports the interrupt routing incorrectly. I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything. We need ".ISA_." instead.Thank you Johann-Nikolaus Andreae
for patiently testing this patch.See http://bugzilla.kernel.org/show_bug.cgi?id=4773

While backporting 72dc67a69690288538142df73a7e3ac66fea68dc, a gfn_to_page()
call was duplicated instead of moved (due to an unrelated patch not being
present in mainline). This caused a page reference leak, resulting in a
fairly massive memory leak.Fix by removing the extraneous gfn_to_page() call.

The vmx hardware state restore restores the tss selector and base address, but
not its length. Usually, this does not matter since most of the tss contents
is within the default length of 0x67. However, if a process is using ioperm()
to grant itself I/O port permissions, an additional bitmap within the tss,
but outside the default length is consulted. The effect is that the process
will receive a SIGSEGV instead of transparently accessing the port.Fix by restoring the tss length. Note that i386 had this working already.
Closes bugzilla 10246.

lockdep goes off on the iova copy_reserved_iova() because it and a function
it calls grabs locks in the from, and the to of the copy operation.The function grab locks of the same lock classes triggering the warning. The
first lock grabbed is for the constant reserved areas that is never accessed
after early boot. Technically you could do without grabbing the locks for the
"from" structure its copying reserved areas from.But dropping the from locks to me looks wrong, even though it would be ok.
The affected code only runs in early boot as its setting up the DMAR
engines.This patch gives the reserved_ioval_list locks special lockdep classes.

The VIA VT6212 defaults to only waiting 1us between passes over EHCI's
async ring, which hammers PCI badly ... and by preventing other devices
from accessing the bus, causes problems like drops in IDE throughput,
a problem that's been bugging users of those chips for several years.A (partial) datasheet for this chip eventually turned up, letting us
see how to make it use a VIA-specific register to switch over to the
the normal 10us value instead, as suggested by the EHCI specification
Solution noted by Lev A. Melnikovsky.It's not clear whether this register exists on other VIA chips; we
know that it's ineffective on the vt8235. So this patch only applies
to chips that seem to be incarnations of the (discrete) vt6212.Signed-off-by: Rene Herman
