76382b5bdb sh: Ensure all PG_dcache_dirty pages are written back.
With some of the cache rework an address aliasing optimization was added,
but this managed to fail on certain mappings resulting in pages with
PG_dcache_dirty set never writing back their dcache lines. This patch
reverts to the earlier behaviour of simply always writing back when the
dirty bit is set.

32b53076c3 serial: sh-sci: Convert tremaining ctrl_xxx I/O routines to __raw_xxx.
ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard
API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.

57eb81b14e i2c-omap: OMAP3: Fix I2C lockup during timeout/error cases
Current OMAP3 I2C driver code does not follow the correct sequence for soft
reset. Due to this, lock up issues are reported during timeout/error cases.

This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM
for soft reset. As per TRM, I2C controller needs to be disabled as a first
step during soft reset.

Here is correct soft reset sequence:
a. Ensure that the module is disabled
(clear the I2Ci.I2C_CON[15] I2C_EN bit to 0).
b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1.
c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1.
d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to
indicate the software reset is complete.

Tested on Zoom2, Zoom3, 3430SDP and 3630SDP

07ac31f6f4 i2c-omap: Don't write IE state in unidle if 0
Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer
to support off-mode) introduced a change which make the dev->iestate
contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle
is called.  Previously, the state was only written if it wasn't equal
to zero.

In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),
in which case dev->iestate has not yet been initialized and will be set
to zero.  Having this value written to the registers causes deadlock
while booting.

As such, this change restores the original functionality.

2f99f5c8f0 Revert "x86, ucode-amd: Ensure ucode update on suspend/resume after CPU off/online cycle"
This reverts commit 9f15226e75.  It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.

As Rafael says:
 "... it causes microcode_init_cpu() to be called during resume even for
  CPUs for which there's no microcode to apply.  That, in turn, results
  in executing request_firmware() (on Intel CPUs at least) which doesn't
  work at this stage of resume (we have device interrupts disabled, I/O
  devices are still suspended and so on).

  If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
  known to us" , so before commit 9f15226e75 microcode_resume_cpu() was
  called for all CPUs already in the system during suspend, which was
  the right thing to do.  The commit changed it so that the CPUs without
  microcode to apply are now treated as "unknown", which is not quite
  right.

  The problem this commit attempted to solve has to be handled
  differently."

37e9066b2f USB: Fix a bug on appledisplay.c regarding signedness
brightness status is reported by the Apple Cinema Displays as an
'unsigned char' (u8) value, but the code used 'char' instead.

Note that he driver was developed on the PowerPC architecture,
where the two types are synonymous, which is not always the case.

Fixed that.  Otherwise the driver will interpret brightness
levels > 127 as negative, and fail to load.

31844d5580 USB: ftdi_sio: isolate all device IDs to new ftdi_sio_ids.h header
This is a strictly move-only patch to relocate all FTDI device
product ID definitions to their own ftdi_sio_ids.h header
(following the usual *_ids.h kernel tree convention, too),
thus correcting the slightly too messy appearance
(crucial driver defines were stuck somewhere in the decaying middle swamp
of the huge existing header).

Compile-tested, based on latest mainline git.

ac06c06770 USB: emi62: fix crash when trying to load EMI 6|2 firmware
While converting emi62 to use request_firmware(), the driver was also
changed to use the ihex helper functions.  However, this broke the loading
of the FPGA firmware because the code tries to access the addr field of
the EOF record which works with a plain array that has an empty last
record but not with the ihex helper functions where the end of the data is
signaled with a NULL record pointer, resulting in:

BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62]

This can be fixed by changing the loop condition to test the return value
of ihex_next_binrec() directly (like in emi26.c).

179192d38e USB: Fix double-linking of drivers/usb/otg when ULPI is selected
This patch corrects a problem where drivers/usb/otg is linked twice
if CONFIG_USB_ULPI is selected, resulting in a build error (symbol
conflict). The files in that directory are properly linked already
as part of CONFIG_USB, and need not be indicated specifically for
CONFIG_USB_ULPI.

da307123c6 USB: fix bugs in usb_(de)authorize_device
This patch (as1315) fixes some bugs in the USB core authorization
code:

	usb_deauthorize_device() should deallocate the device strings
	instead of leaking them, and it should invoke
	usb_destroy_configuration() (which does proper reference
	counting) instead of freeing the config information directly.

	usb_authorize_device() shouldn't change the device strings
	until it knows that the authorization will succeed, and it should
	autosuspend the device at the end (having autoresumed the
	device at the start).

	Because the device strings can be changed, the sysfs routines
	to display the strings must protect the string pointers by
	locking the device.

8d8558d108 USB: rename usb_configure_device
This patch (as1314) renames usb_configure_device() and
usb_configure_device_otg() in the hub driver.  Neither name is
appropriate because these routines enumerate devices, they don't
configure them.  That's handled by usb_choose_configuration() and
usb_set_configuration().

b2cd41496c Staging/vt66*: kconfig, depends on WLAN
The vt665[56] drivers can be built when CONFIG_NET=n &
CONFIG_NETDEVICES=n or just when CONFIG_WLAN=n.
This leads to build failures.
Prevent this by making them depend on WLAN.

still needs to be re-applied.]
