Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fix from Thomas Gleixner:
"A single fix for a cpu hotplug race vs. interrupt descriptors:
Prevent irq setup/teardown across the cpu starting/dying parts of cpu
hotplug so that the starting/dying cpu has a stable view of the
descriptor space. This has been an issue for all architectures in the
cpu dying phase, where interrupts are migrated away from the dying
cpu. In the starting phase its mostly a x86 issue vs the vector space
update"

Q: Can I suspend-to-disk using a swap partition under LVM?
-A: No. You can suspend successfully, but you'll not be able to

+A: Yes and No. You can suspend successfully, but the kernel will not be able
+to resume on its own. You need an initramfs that can recognize the resume
+situation, activate the logical volume containing the swap volume (but not
+touch any filesystems!), and eventually call
+
+echo -n "$major:$minor" > /sys/power/resume
+
+where $major and $minor are the respective major and minor device numbers of

+ * ioremap() and friends.
*
- * ioremap takes a PCI memory address, as specified in
- * Documentation/io-mapping.txt.
+ * ioremap() takes a resource address, and size. Due to the ARM memory
+ * types, it is important to use the correct ioremap() function as each
+ * mapping has specific properties.
*
+ * Function Memory type Cacheability Cache hint
+ * ioremap() Device n/a n/a
+ * ioremap_nocache() Device n/a n/a
+ * ioremap_cache() Normal Writeback Read allocate
+ * ioremap_wc() Normal Non-cacheable n/a
+ * ioremap_wt() Normal Non-cacheable n/a
+ *
+ * All device mappings have the following properties:
+ * - no access speculation
+ * - no repetition (eg, on return from an exception)
+ * - number, order and size of accesses are maintained
+ * - unaligned accesses are "unpredictable"
+ * - writes may be delayed before they hit the endpoint device
+ *
+ * ioremap_nocache() is the same as ioremap() as there are too many device
+ * drivers using this for device registers, and documentation which tells
+ * people to use it for such for this to be any different. This is not a
+ * safe fallback for memory-like mappings, or memory regions where the
+ * compiler may generate unaligned accesses - eg, via inlining its own
+ * memcpy.
+ *
+ * All normal memory mappings have the following properties:
+ * - reads can be repeated with no side effects
+ * - repeated reads return the last value written
+ * - reads can fetch additional locations without side effects
+ * - writes can be repeated (in certain cases) with no side effects
+ * - writes can be merged before accessing the target
+ * - unaligned accesses can be supported
+ * - ordering is not guaranteed without explicit dependencies or barrier
+ * instructions
+ * - writes may be delayed before they hit the endpoint memory
+ *
+ * The cache hint is only a performance hint: CPUs may alias these hints.
+ * Eg, a CPU not implementing read allocate but implementing write allocate
+ * will provide a write allocate mapping instead.
