Maxime Ripard 09504a7d76 ARM: sunxi: dt: Convert to the new irq controller compatibles
Switch the device tree to the new compatibles introduced in the irqchip drivers
to have a common pattern accross all Allwinner SoCs.

Maxime Ripard a7e8b4b519 irqchip: sunxi: Change compatibles
The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Change the compatibles
to match the other pattern in the irq controller driver for consistency.

Thomas Gleixner c1bacbae81 genirq: Provide irq_request/release_resources chip callbacks
For certain irq types, e.g. gpios, it's necessary to request resources
before starting up the irq.

This might fail so we cannot use the irq_startup() callback because we
might call the irq_set_type() callback before that which does not make
sense when the resource is not available. Calling irq_startup() before
irq_set_type() can lead to spurious interrupts which is not desired
either.

Thomas Gleixner 1ed71e59bc parisc: Validate online cpus in irq_set_affinity() callbacks
The [user space] interface does not filter out offline cpus. It merily
guarantees that the mask contains at least one online cpu.

So the selector in the irq chip implementation needs to make sure to
pick only an online cpu because otherwise:

     Offline Core 1
     Set affinity to 0xe (is valid due to online mask 0xd)
     cpumask_first will pick core 1, which is offline

David Howells 979e0d7465 KEYS: Make the keyring cycle detector ignore other keyrings of the same name
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:
	  search_nested_keyrings+0x76/0x2aa
	  __key_link_check_live_key+0x50/0x5f
	  key_link+0x4e/0x85
	  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:

Pull thermal fixes from Zhang Rui:
 "Specifics:

   - Update the help text of INT3403 Thermal driver, which was not
     friendly to users.  From Zhang Rui.

   - The "type" sysfs attribute of x86_pkg_temp_thermal registered
     thermal zones includes an instance number, which makes the
     thermal-to-hwmon bridge fails to group them all in a single hwmon
     device.  Fixed by Jean Delvare.

   - The hwmon device registered by x86_pkg_temp_thermal driver is
     redundant because the temperature value reported by
     x86_pkg_temp_thermal is already reported by the coretemp driver.
     Fixed by Jean Delvare.

   - Fix a problem that the cooling device can not be updated properly
     if it is initialized at max cooling state.  From Ni Wade.

   - Fix a problem that OF registered thermal zones are running without
     thermal governors.  From Zhang Rui.

   - Commit beeb5a1e0e ("thermal: rcar-thermal: Enable driver
