Merge branch 'linus' into x86/spinlocks

Done to prevent this failure of an Octopus merge:

 Added arch/arm/include/asm/byteorder.h in both, but differently.
 ERROR: Merge conflict in arch/arm/include/asm/byteorder.h
 Auto-merging include/asm-x86/spinlock.h
 ERROR: Merge conflict in include/asm-x86/spinlock.h
 fatal: merge program failed

-	  This setting is irrelevant for most IDE disks, with direct memory

-	  Input/Output. On some systems, it also can increase the data
-	  throughput of Programmed Input/Output. Some drives, however, seemed
-	  to run slower with multiple sector mode enabled. Some drives claimed
-	  to support multiple sector mode, but lost data at some settings.

+	  This is the generic IDE driver.  This driver attaches to the
+	  fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+	  so on).  Please note that if this driver is built into the

+	  may grab those ports and thus can prevent the controller
+	  specific driver from attaching.

+	  Also, currently, IDE generic doesn't allow IRQ sharing
+	  meaning that the IRQs it grabs won't be available to other
+	  controllers sharing those IRQs which usually makes drivers
+	  for those controllers fail.  Generally, it's not a good idea
+	  to load IDE generic driver on modern systems.
