+Subject: ACPI: run _OSC after ACPI_FULL_INITIALIZATION
+
+From: Lin Ming <ming.m.lin@intel.com>
+
+commit fc54ab72959edbf229b65ac74b2f122d799ca002 upstream.
+
+The _OSC method may exist in module level code,
+so it must be called after ACPI_FULL_INITIALIZATION
+
+On some new platforms with Zero-Power-Optical-Disk-Drive (ZPODD)
+support, this fix is necessary to save power.

+Subject: drivers/scsi/atp870u.c: fix bad use of udelay
+
+From: Martin Michlmayr <tbm@cyrius.com>
+
+commit 0f6d93aa9d96cc9022b51bd10d462b03296be146 upstream.
+
+The ACARD driver calls udelay() with a value > 2000, which leads to to
+the following compilation error on ARM:
+
+ ERROR: "__bad_udelay" [drivers/scsi/atp870u.ko] undefined!
+ make[1]: *** [__modpost] Error 1
+
+This is because udelay is defined on ARM, roughly speaking, as
+
+ #define udelay(n) ((n) > 2000 ? __bad_udelay() : \
+ __const_udelay((n) * ((2199023U*HZ)>>11)))
+
+The argument to __const_udelay is the number of jiffies to wait divided
+by 4, but this does not work unless the multiplication does not
+overflow, and that is what the build error is designed to prevent. The
+intended behavior can be achieved by using mdelay to call udelay
+multiple times in a loop.

+Subject: kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()
+
+From: Shawn Guo <shawn.guo@linaro.org>
+
+commit f96972f2dc6365421cf2366ebd61ee4cf060c8d5 upstream.
+
+As kernel_power_off() calls disable_nonboot_cpus(), we may also want to
+have kernel_restart() call disable_nonboot_cpus(). Doing so can help
+machines that require boot cpu be the last alive cpu during reboot to
+survive with kernel restart.
+
+This fixes one reboot issue seen on imx6q (Cortex-A9 Quad). The machine
+requires that the restart routine be run on the primary cpu rather than
+secondary ones. Otherwise, the secondary core running the restart
+routine will fail to come to online after reboot.

+Subject: mfd: max8925: Move _IO resources out of ioport_ioresource
+
+From: Mark Brown <broonie@opensource.wolfsonmicro.com>
+
+commit bee6e1fa617b1fb7f6f91033428410e05f5ab0ed upstream.
+
+The removal of mach/io.h from most ARM platforms also set the range of
+valid IO ports to be empty for most platforms when previously any 32
+bit integer had been valid. This makes it impossible to add IO resources
+as the added range is smaller than that of the root resource for IO ports.
+
+Since we're not really using IO memory at all fix this by defining our
+own root resource outside the normal tree and make that the parent of
+all IO resources. This also ensures we won't conflict with read IO ports
+if we ever run on a platform which happens to use them.

+
+commit dfb117b3e50c52c7b3416db4a4569224b8db80bb upstream.
+
+Check whether we evaluated _ADR successfully. Previously we ignored
+failure, so we would have used garbage data from the stack as the device
+and function number.
+
+We return AE_OK so that we ignore only this slot and continue looking
+for other slots.
