[ARM] Orion: fix PCIe inbound window programming when RAM size is not a power of two
The PCIe inbound window size is supposed to be a power of two. If
the total amount of RAM installed in the system is not a power of two,
round it up such that it is.

Current OMAP3 I2C driver code does not follow the correct sequence for soft

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.

In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),

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 9f15226e755 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."

The hash implies this is not exact and can sometimes not print a

USB: option: support hi speed for modem Haier CE100
I made this patch for usbserial driver to add the support for EVDO modem
Haier CE100. The bugs report for this is here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/490068
This patch based on these post:
http://blankblondtank.wordpress.com/2009/09/04/mengoptimalkan-koneksi-modem-haier-ce-100-cdma-di-linux/
http://tantos.web.id/blogs/how-to-internet-connection-using-cdma-evdo-modem-and-karmic-koala-ubuntu-9-10
I hope this patch can help other that have the Haier C100 modem, mostly in my country, Indonesia.

Some of these workarounds are already in place, but labeled as affecting

from the FIFO, implement the workaround there too when necessary.

Race condition exists between the cppi_interrupt handler and

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]

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.
