Matthieu CASTET and Michael Grzeschik mentioned isr_tr_complete_handler
is a bit messy at below:
http://marc.info/?l=linux-usb&m=139047775001152&w=2

This commit creates a new function isr_setup_packet_handler to handle
setup packet, it makes isr_tr_complete_handler easy to read.

This is no functional change at this commit, tested with g_mass_storage
and g_ether.

 "A collection of fixes for ARM platforms.  A little large due to us
  missing to do one last week, but there's nothing in particular here
  that is in itself large and scary.

  Mostly a handful of smaller fixes all over the place.  The majority is
  made up of fixes for OMAP, but there are a few for others as well.  In
  particular, there was a decision to rename a binding for the Broadcom
  pinctrl block that we need to go in before the final release since we
  then treat it as ABI"

  staging/cxt1e1/linux.c: Correct arbitrary memory write in c4_ioctl()

This fixes CVE-2014-0102.

The following command sequence produces an oops:

	keyctl new_session
	i=`keyctl newring _ses @s`
	keyctl link @s $i

The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.

Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...

The oops looks something like this:

	kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
	invalid opcode: 0000 [#1] SMP
	...
	RIP: keyring_detect_cycle_iterator+0xe/0x1f
	...
	Call Trace:

	  keyctl_keyring_link+0x60/0x81
	  SyS_keyctl+0x65/0xe4
	  tracesys+0xdd/0xe2

The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().

A testcase has been included in the keyutils testsuite for this:

When reading the transfer result data for an isochronous in request, if

actual_length is a multiple of the DTI endpoint max packet size, combine

   those machines.  From Kieran Clancy.

 - If the ACPI sleep control and status registers are not present (which
