2013-05-20TTY: Fix tty miss restart after we turn off flow-controlWang YanQing
I meet emacs hang in start if I do the operation below: 1: echo 3 > /proc/sys/vm/drop_caches 2: emacs BigFile 3: Press CTRL-S follow 2 immediately Then emacs hang on, CTRL-Q can't resume, the terminal hang on, you can do nothing with this terminal except close it. The reason is before emacs takeover control the tty, we use CTRL-S to XOFF it. Then when emacs takeover the control, it may don't use the flow-control, so emacs hang. This patch fix it. This patch will fix a kind of strange tty relation hang problem, I believe I meet it with vim in ssh, and also see below bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=465823 Signed-off-by: Wang YanQing <udknight@gmail.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-05-20tty/vt: Fix vc_deallocate() lock orderPeter Hurley
Now that the tty port owns the flip buffers and i/o is allowed from the driver even when no tty is attached, the destruction of the tty port (and the flip buffers) must ensure that no outstanding work is pending. Unfortunately, this creates a lock order problem with the console_lock (see attached lockdep report [1] below). For single console deallocation, drop the console_lock prior to port destruction. When multiple console deallocation, defer port destruction until the consoles have been deallocated. tty_port_destroy() is not required if the port has not been used; remove from vc_allocate() failure path.

2013-05-20serial: 8250_dw: Add valid clk pointer checkEzequiel Garcia
Commit ffc3ae6dd "serial: 8250_dw: Enable runtime PM" introduced runtime PM management, which enables/disables the clk without checking if the clk is valid. However, this driver allows to be probed without a defined clk, using clock-frequency, as a fallback. Therefore, on platforms that are device tree probed using clock-frequency instead of clk, we get an ugly NULL pointer dereference. This patch fixes it by simply adding a check before accessing the clk api.

2013-05-20x86: Fix bit corruption at CPU resume timeLinus Torvalds
In commit 78d77df71510 ("x86-64, init: Do not set NX bits on non-NX capable hardware") we added the early_pmd_flags that gets the NX bit set when a CPU supports NX. However, the new variable was marked __initdata, because the main _use_ of this is in an __init routine. However, the bit setting happens from secondary_startup_64(), which is called not only at bootup, but on every secondary CPU start. Including resuming from STR and at CPU hotplug time. So the value cannot be __initdata.
