Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.

The mmap_region() code would temporarily set the VM_ACCOUNT flag for anonymous shared mappings just to inform shmem_zero_setup() that it should enable accounting for the resulting shm object. It would then clear the flag after calling ->mmap (for the /dev/zero case) or doing shmem_zero_setup() (for the MAP_ANON case). This just resulted in vma merge issues, but also made for just unnecessary confusion. Use the already-existing VM_NORESERVE flag for this instead, and let shmem_{zero|file}_setup() just figure it out from that. This also happens to make it obvious that the new DRI2 GEM layer uses a non-reserving backing store for its object allocation - which is quite possibly not intentional. But since I didn't want to change semantics in this patch, I left it alone, and just updated the caller to use the new flag semantics. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When using sgmii the link was not being properly passed up to the driver from the underlying link management functions.

A panic has been observed with frame sizes smaller than 1K. This has been root caused to the hardware spanning larger frames across multiple buffers and then reporting the original frame size in the first descriptor. To prevent this we can enable set the LPE bit which in turn will restrict packet sizes to those set in the RLPML register.

As the mmap handler gets called under mmap_sem, and we may grab mmap_sem elsewhere under the socket lock to access user data, we should avoid grabbing the socket lock in the mmap handler. Since the only thing we care about in the mmap handler is for pg_vec* to be invariant, i.e., to exclude packet_set_ring, we can achieve this by simply using a new mutex.

Currently we use a spin-lock to serialise statistics fetches and also to inhibit them for short periods of time, plus a flag to enable/disable statistics fetches for longer periods of time, during online reset.

All 10Xpress PHYs require autonegotiation all the time; enforce this in the set_settings() method and do not treat it as a workaround. Remove claimed support for 100M HD mode since it is not supported by current firmware. Do not set speed override bits when AN is enabled, and do not use register 1.49192 for AN configuration as it can override what we set elsewhere. Always set the AN selector bits to 1 (802.3).

Early versions of the SFX7101 firmware could complete link training in a state where it would not adequately cancel noise (Solarflare bug 10750). We previously worked around this by resetting the PHY after seeing many Ethernet CRC errors. This workaround is unsafe since it takes no account of the interval between errors; it also appears to be unnecessary with production firmware. Therefore remove it.

Impact: prevent false positive WARN_ON() in clockevents_program_event() clock_was_set() changes the base->offset of CLOCK_REALTIME and enforces the reprogramming of the clockevent device to expire timers which are based on CLOCK_REALTIME. If the clock change is large enough then the subtraction of the timer expiry value and base->offset can become negative which triggers the warning in clockevents_program_event(). Check the subtraction result and set a negative value to 0. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Impact: fix CPU hotplug hang on Power6 testbox On architectures that support offlining all cpus (at least powerpc/pseries), hot-unpluging the tick_do_timer_cpu can result in a system hang. This comes from the fact that if the cpu going down happens to be the cpu doing the tick, then as the tick_do_timer_cpu handover happens after the cpu is dead (via the CPU_DEAD notification), we're left without ticks, jiffies are frozen and any task relying on timers (msleep, ...) is stuck. That's particularly the case for the cpu looping in __cpu_die() waiting for the dying cpu to be dead. This patch addresses this by having the tick_do_timer_cpu handover happen earlier during the CPU_DYING notification. For this, a new clockevent notification type is introduced (CLOCK_EVT_NOTIFY_CPU_DYING) which is triggered in hrtimer_cpu_notify().
