commit 078c04545ba56da21567728a909a496df5ff730d upstream.

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.

This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

commit 9c5fd9e85f574d9d0361b2b878f55732290afe5b upstream.

atags_to_fdt() returns 1 when it fails to find a valid FDT signature.
The CONFIG_ARM_ATAG_DTB_COMPAT code is supposed to retry with another
location, but only does so when the initial call doesn't fail.

Fix this by using the correct condition in the assembly code.

commit cca0355a09b1bfe9f8985285199a346e13cacf39 upstream.

Due to an error while handling vbus_pin_active_low in ohci-at91 driver,
the specification of this property was not good in devices/board files.

commit 8c3ec84102d171a24f050a086bfc546e9de93f9f upstream.

Commit 4a53f4e "USB: ehci-tegra: add probing through device tree" added
AUXDATA for Tegra's USB/EHCI controller. However, it pointed the platform
data at a location containing the address of the intended platform data,
rather than the platform data itself. This change fixes that.

commit f35b431dde39fb40944d1024f08d88fbf04a3193 upstream.

The ARM IP revisions in Tegra are:
Tegra20: CPU r1p1, PL310 r2p0
Tegra30: CPU A01=r2p7/>=A02=r2p9, NEON r2p3-50, PL310 r3p1-50

Based on work by Olof Johansson, although the actual list of errata is
somewhat different here, since I added a bunch more and removed one PL310
erratum that doesn't seem applicable.

Commit 2ee619f9487c2acc1efdf2c78e68e2bd51b635fa upstream.

Make the TMU clocksource driver mark its device as "always on"
using pm_genpd_dev_always_on() to protect it from surprise power
removals and make sh7372_add_standard_devices() add TMU devices on
sh7372 to the A4R power domain so that their "always on" flags
are taken into account as appropriate.
