+Subject: can: dev: fix crtlmode_supported check
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit 9b1087aa5e86448fe6ad40a58964e35f3ba423d5 upstream.
+
+When changing flags in the CAN drivers ctrlmode the provided new content has to
+be checked whether the bits are allowed to be changed. The bits that are to be
+changed are given as a bitfield in cm->mask. Therefore checking against
+cm->flags is wrong as the content can hold any kind of values.
+
+The iproute2 tool sets the bits in cm->mask and cm->flags depending on the
+detected command line options. To be robust against bogus user space
+applications additionally sanitize the provided flags with the provided mask.

+Subject: clocksource: exynos_mct: Fix bitmask regression for exynos4_mct_write
+
+From: Tobias Jakobi <tjakobi@math.uni-bielefeld.de>
+
+commit 8c38d28ba8da98f7102c31d35359b4dbe9d1f329 upstream.
+
+EXYNOS4_MCT_L_MASK is defined as 0xffffff00, so applying this bitmask
+produces a number outside the range 0x00 to 0xff, which always results
+in execution of the default switch statement.
+
+Obviously this is wrong and git history shows that the bitmask inversion
+was incorrectly set during a refactoring of the MCT code.
+
+Fix this by putting the inversion at the correct position again.

+Subject: x86/tsc: Change Fast TSC calibration failed from error to info
+
+From: Alexandre Demers <alexandre.f.demers@gmail.com>
+
+commit 520452172e6b318f3a8bd9d4fe1e25066393de25 upstream.
+
+Many users see this message when booting without knowning that it is
+of no importance and that TSC calibration may have succeeded by
+another way.
+
+As explained by Paul Bolle in
+http://lkml.kernel.org/r/1348488259.1436.22.camel@x61.thuisdomein
+
+ "Fast TSC calibration failed" should not be considered as an error
+ since other calibration methods are being tried afterward. At most,
+ those send a warning if they fail (not an error). So let's change
+ the message from error to warning.
+
+[ tglx: Make if pr_info. It's really not important at all ]
+
