Back in commit 5136b2da770d ("PCI: convert bus code to use dev_groups"),
I misstyped the 'enable' sysfs filename as 'enabled', which broke the
userspace API. This patch fixes that issue by renaming the file back.

The four port serial port on the zoom debug board uses a TL16CP754C
with a single interrupt and GPMC chip select. The serial ports each
use a 8 bytes for IO registers, and are 256 bytes apart on the GPMC
line.
Let's add timings for all four ports so we can remove the GPMC
workarounds for using bootloader timings.
Not caused by this patch, but looks like u-boot only properly
initializes the fifo on the first serial port. Currently the other
ports produce garbage at least with my version of u-boot. I suspect
that TL16CP754C needs non-standard initialization added to 8250
driver to properly fix this issue.

The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.
The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.
Let's fix the issue according to the following table:
Device GPMC partition size Device IO size
connected in the ranges entry in the reg entry
NAND 0x01000000 (16MB) 4
16550 0x01000000 (16MB) 8

ext4_ext_convert_to_initialized() can return more blocks than are
actually allocated from map->m_lblk in case where initial part of the
on-disk extent is zeroed out. Luckily this doesn't have serious
consequences because the caller currently uses the return value
only to unmap metadata buffers. Anyway this is a data
corruption/exposure problem waiting to happen so fix it.

When clearing inode journal flag, we call jbd2_journal_flush() to force
all the journalled data to their final locations. Currently we ignore
when this fails and continue clearing inode journal flag. This isn't a
big problem because when jbd2_journal_flush() fails, journal is likely
aborted anyway. But it can still lead to somewhat confusing results so
rather bail out early.

When ext4_handle_dirty_dx_node() or ext4_handle_dirty_dirent_node()
fail, there's really something wrong with the fs and there's no point in
continuing further. Just return error from make_indexed_dir() in that
case. Also initialize frames array so that if we return early due to
error, dx_release() doesn't try to dereference uninitialized memory
(which could happen also due to error in do_split()).

Incoming packet is dropped silently by sk_filter(), if the skb was
allocated from pfmemalloc reserves and the corresponding socket is
not marked with the SOCK_MEMALLOC flag.
Igb driver allocates pages for DMA with __skb_alloc_page(), which
calls alloc_pages_node() with the __GFP_MEMALLOC flag. So, in case
of OOM condition, igb can get pages with pfmemalloc flag set.
If an incoming packet hits the pfmemalloc page and is large enough
(small packets are copying into the memory, allocated with
netdev_alloc_skb_ip_align(), so they are not affected), it will be
dropped.
This behavior is ok under high memory pressure, but the problem is
that the igb driver reuses these mapped pages. So, packets are still
dropping even if all memory issues are gone and there is a plenty
of free memory.
In my case, some TCP sessions hang on a small percentage (< 0.1%)
of machines days after OOMs.
Fix this by avoiding reuse of such pages.

After '#echo mem > /sys/power/state' some devices can not be properly resumed
because apparently the MTD Partition Configuration Register has been reset
to default thus the rootfs cannot be mounted cleanly on resume.
An example of this can be found in the SA-1100 Developer's Manual at 9.5.3.3
where the second step of the Sleep Shutdown Sequence is described:
"An internal reset is applied to the SA-1100. All units are reset...".
As workaround we refresh the PCR value as done initially on chip setup.
This behavior and the fix are confirmed by our tests done on 2 different Zaurus
collie units with kernel 3.17.

The TMU timers used the generic compatible property only.
Add the SoC-specific one, to make it future proof.

The CMT1 timer used the generic compatible property only.
Add the SoC-specific one, which is already documented, to make it future
proof.

Enable HS-USB device for the Henninger board, defining the GPIO that the driver
should check when probing (which is the ID output from MAX3355 OTG chip).
Note that there will be pinctrl-related error messages if both internal PCI
and HS-USB drivers are enabled but they should be just ignored.

Enable HS-USB device for the Lager board, defining the GPIO that the driver
should check when probing. Since this board doesn't have the OTG ID pin, we
assume that GP5_18 (USB0_PWEN) is an ID pin because it is 1 when the SW5 is
in position 2-3 (meaning USB function) and 0 in other positions.
Note that there will be pinctrl-related error messages if both internal PCI
and HS-USB drivers are enabled but they should be just ignored.

Since the PHY of USB3.0 and EHCI/OHCI ch2 are the same, the USB3.0
driver cannot use the phy driver when the EHCI/OHCI ch2 already used it:
phy phy-e6590100.usb-phy.3: phy init failed --> -16
xhci-hcd: probe of ee000000.usb failed with error -16
If so, we have to unbind the EHCI/OHCI ch2, and then we have to bind
the USB3.0 driver as the following:
echo 0000:02:02.0 > /sys/bus/pci/drivers/ehci-pci/unbind
echo 0000:02:01.0 > /sys/bus/pci/drivers/ohci-pci/unbind
echo ee000000.usb > /sys/bus/platform/drivers/xhci-hcd/bind
Note that there will be pinctrl-related error messages if both
internal PCI and USB3.0 are enabled but they should be just ignored:
sh-pfc e6060000.pfc: pin GP_5_22 already requested by ee0d0000.pci; cannot claim for ee000000.usb
sh-pfc e6060000.pfc: pin-182 (ee000000.usb) status -22
ata1: SATA link down (SStatus 0 SControl 300)
sh-pfc e6060000.pfc: could not request pin 182 (GP_5_22) from group usb2 on device sh-pfc
