For backward compatibility, we still keep the deprecated form, and will warn the users if they still use the deprecated one, like this: drivers/block/drbd/drbd_bitmap.c: In function ‘bm_page_io_async’: drivers/block/drbd/drbd_bitmap.c:973:3: warning: ‘kmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:124) drivers/block/drbd/drbd_bitmap.c:977:3: warning: ‘kunmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:144) Thanks to Nick Bowler for the cpp trick!

2012-03-20hwmon: (sch56xx) Add support for the integrated watchdog (v2)Hans de Goede
Add support for the watchdog integrated into the SMSC SCH5627 and SCH5636 superio-s. Since the watchdog is part of the hwmon logical device and thus shares ioports with it, the watchdog driver is integrated into the existing hwmon drivers for these. Note that this version of the watchdog support for sch56xx superio-s implements the watchdog chardev interface itself, rather then relying on the recently added watchdog core / watchdog_dev. This is done because currently some needed functionality is missing from watchdog_dev, as soon as this functionality is added (which is being discussed on the linux-watchdog mailinglist), I'll convert this driver over to using watchdog_dev.

2012-03-20HID: multitouch: add PID for Fructel productAndreas Nielsen
Adds multitouch support for the Gametel Android game controller. The multitouch events are emulated by the Gametel device. Each physical button is configured to generate a MT event on a specific coordinate. This seems to be the only way for us to support Android games that doesn't support HID gamepads. It is possible to inject MT events at Android level, but this requires root on the phone. Signed-off-by: Andreas Nielsen <eas@svep.se> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2012-03-20KVM: Convert intx_mask_lock to spin lockJan Kiszka
As kvm_notify_acked_irq calls kvm_assigned_dev_ack_irq under rcu_read_lock, we cannot use a mutex in the latter function. Switch to a spin lock to address this.

2012-03-20KVM: x86: fix kvm_write_tsc() TSC matching thinkoMarcelo Tosatti
kvm_write_tsc() converts from guest TSC to microseconds, not nanoseconds as intended. The result is that the window for matching is 1000 seconds, not 1 second. Microsecond precision is enough for checking whether the TSC write delta is within the heuristic values, so use it instead of nanoseconds. Noted by Avi Kivity.

2012-03-20x86: kvmclock: abstract save/restore sched_clock_stateMarcelo Tosatti
Upon resume from hibernation, CPU 0's hvclock area contains the old values for system_time and tsc_timestamp. It is necessary for the hypervisor to update these values with uptodate ones before the CPU uses them. Abstract TSC's save/restore sched_clock_state functions and use restore_state to write to KVM_SYSTEM_TIME MSR, forcing an update. Also move restore_sched_clock_state before __restore_processor_state, since the later calls CONFIG_LOCK_STAT's lockstat_clock (also for TSC). Thanks to Igor Mammedov for tracking it down. Fixes suspend-to-disk with kvmclock. Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
