Revert "tty/8250_pnp: serial port detection regression since v3.7"

2013-04-12T16:52:13+00:00

commit c12f9ea28e9fbe7b1f4cefc953bee33298370683 upstream. This reverts commit 77e372a3d82e5e4878ce1962207edd766773cc76. Checking for disabled resources board breaks detection pnp on another board "AMI UEFI implementation (Version: 0406 Release Date: 06/06/2012)". I'm working with the reporter of the original bug to write and test a better fix. https://bugzilla.redhat.com/show_bug.cgi?id=928246 Signed-off-by: Sean Young Signed-off-by: Greg Kroah-Hartman

rt2x00: rt2x00pci_regbusy_read() - only print register access failure once

2013-04-12T16:52:13+00:00

commit 83589b30f1e1dc9898986293c9336b8ce1705dec upstream. BugLink: http://bugs.launchpad.net/bugs/1128840 It appears that when this register read fails it never recovers, so I think there is no need to repeat the same error message ad infinitum.

vfio-pci: Fix possible integer overflow

2013-04-12T16:52:12+00:00

commit 904c680c7bf016a8619a045850937427f8d7368c upstream. The VFIO_DEVICE_SET_IRQS ioctl takes a start and count parameter, both of which are unsigned. We attempt to bounds check these, but fail to account for the case where start is a very large number, allowing start + count to wrap back into the valid range. Bounds check both start and start + count. Reported-by: Dan Carpenter Signed-off-by: Alex Williamson Signed-off-by: Greg Kroah-Hartman

r8169: fix auto speed down issue

2013-04-12T16:52:12+00:00

commit e2409d83434d77874b461b78af6a19cd6e6a1280 upstream. It would cause no link after suspending or shutdowning when the nic changes the speed to 10M and connects to a link partner which forces the speed to 100M. Check the link partner ability to determine which speed to set. Signed-off-by: Hayes Wang Acked-by: Francois Romieu Signed-off-by: David S.

commit 6e45eb12fd1c741d556bf264ee98853b5f3104e5 upstream. Boot_freq is for saving booting freq. But exynos_cpufreq_cpu_init is called in hotplug.
