This isolates the custom S3C64xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x64xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.
Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead
roof the number of GPIOs for this platform:
First sum up all the GPIO banks from A to Q: 187 GPIOs.
Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA,
128, so in total maximum 187+16+128 = 331 GPIOs, so let's
take the same roof as for S3C24XX: 512. This way we can do
away with the GPIO calculation macros for GPIO_BOARD_START,
BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

This isolates the custom S3C24xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x24xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.
We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff.
The biggest this can ever be for the S3C24XX is
CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or
CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512
is the absolute roof value on this platform. So we set
the size of ARCH_NR_GPIO to this and the GPIOs array will
fit any S3C24XX platform, as per pattern from other archs.
ChangeLog v2->v3:
- Move the movement of the S3C64XX gpio.h file out of
this patch and into the follow-up patch where it belongs.
ChangeLog v1->v2:
- Added an #ifdef ARCH_S3C24XX around the header inclusion
in drivers/gpio/gpio-samsung.c as we would otherwise
have colliding definitions when compiling S3C64XX.
- Rename inclusion guard in the header file.

In this patch we fix some "logical" errors in bypass.c of the silicom bypass
driver (in staging).
Checkpatch complains about the following errors:
- unnecessary forward declarations in a source file
- assignment in if condition
In addition to that the __init and __exit macros were missing at the init and
cleanup function.
There are still two warnings left for this file related to too many leadingtabs
at nested blocks. I did not touch this issue becasue the code needs really some
refactoring. And since i do not have the appropriate hardware to test the code,
i do not change the functionality in any way.

This patch addresses several problems in bypass.c found by checkpatch.
Furthermore it removes/adds some empty lines to make the code more readable.
The following problems are fixed:
- line over 80 characters
- space after logical operator !
- spaces instead of tabs
- missing empty line after local declarations
- empty line after {
The empty line issues were not discovered by checkpatch but in my opinion these
changes make perfect sense in terms of readability.

Commit e6789cd3dfb553077606ccafeb05e0043f072481 (uio: Simplify uio error
path by using devres functions) converted uio to use devm_request_irq().
This introduced a change in behaviour since the IRQ is associated with
the parent device instead of the created UIO device. The IRQ will remain
active after uio_unregister_device() is called, and some drivers will
crash because of this. The patch fixes this.

Fengguang Wu used CF=-D__CHECK_ENDIAN__ to check the GenWQE driver for
endian issues. Sparse found a couple of those. Most of them were caused
by not correctly handling __be64/32 and __u64/32. Those I was able to
fix with appropriate castings.
One more serious issue was the ATS entry in struct genwqe_ddcb_cmd.
The kernel expected it in big-endian, but the type was defined __u64.
I decided that it is better to keep the interface consistent using
host endian byte-odering instead of having a mixture. With this change
the kernel likes to see host endian byte order for the ATS entry. That
would have been an interface change, if someone would have used the
driver already. Since this is not the case, I hope it is ok to fix it
now.
For the genqwe_readq/writeq/readl/writel functions I enforced the casts.
It still complains, as far as I can see, about some copy_to/from_user()
usages:

pp->io_base, which is the input of the outbound IO address translation
unit, should be the CPU address. It was incorrectly programmed to the
realio address.
We should pass global_io_offset rather than sys->io_offset to
pci_ioremap_io(), so we map the new window into the first available spot in
the Linux view of the I/O space.
We must also pass CPU address instead of realio address to pci_ioremap_io().
This patch fixes above issue. It has been tested with Lecroy PTC in AIC
mode and Pericom PI7C9X2G303EL PCIe switch, which does not work otherwise.

JZ4740 USB Device Controller is not OTG compatible and does not have
DEVCTL register in silicon.
During ethernet-over-usb transactions, on reset, musb driver tries to
read from DEVCTL and consequently sets device as host (A-Device)
instead of peripheral (B-Device), which makes it a composite device to
the USB gadget driver.
This induces a kernel panic during power down where the USB gadget
driver does a null pointer dereference when trying to access the
composite device configuration.
On reset, do not rely on DEVCTL value for setting gadget peripheral
mode. Use is_otg flag instead to set it to B-Device.

In this case, there are two DACs, and DAC 0x03 is mono. In order
to make headphones and front speaker use DAC 0x02, and subwoofer use
DAC 0x03, we artificially cut the connection from nodes 0x14 and 0x15
to node 0x03, so they can only use DAC 0x02.
In addition, the 5460 and 5470 differs in the sense that 5470 also
needs a headset mic patch, whereas 5460 has individual detection for
headphone and headset mic.

[63837.050000] Kernel panic - not syncing: Fatal exception in interrupt
[63837.050000] Rebooting in 3 seconds..
Fix this by not unregistering the conntrack extension in the per-netns
cleanup code.
This bug was introduced in (73f4001 netfilter: nf_ct_tstamp: move
initialization out of pernet_operations).

The __data_loc variable is an unused left over from the 32 bit arm implementation.
Remove that variable and adjust the __mmap_switched startup routine accordingly.

We need to wait for any outstanding DIO to complete in a couple
of situations. Firstly, in case we are changing out of deferred
mode (in inode_go_sync) where GLF_DIRTY will not be set. That
call could be prefixed with a test for gl_state == LM_ST_DEFERRED
but it doesn't seem worth it bearing in mind that the test for
outstanding DIO is very quick anyway, in the usual case that there
is none.
The second case is in inode_go_lock which will catch the cases
where we have a cached EX lock, but where we grant deferred locks
against it so that there is no glock state transistion. We only
need to wait if the state is not deferred, since DIO is valid
anyway in that state.

In patch 209806aba9d540dde3db0a5ce72307f85f33468f we allowed
local deferred locks to be granted against a cached exclusive
lock. That opened up a corner case which this patch now
fixes.
The solution to the problem is to check whether we have cached
pages each time we do direct I/O and if so to unmap, flush
and invalidate those pages. Since the glock state machine
normally does that for us, mostly the code will be a no-op.

In nft's nft_exthdr_eval() routine we process IPv6 extension header
through invoking ipv6_find_hdr(), but we call it with an uninitialized
offset variable that contains some stack value. In ipv6_find_hdr()
we then test if the value of offset != 0 and call skb_header_pointer()
on that offset in order to map struct ipv6hdr into it. Fix it up by
initializing offset to 0 as it was probably intended to be.
