It is written in the Documentation/sysrq.txt that oom-killer is enabled
when we set "64" in /proc/sys/kernel/sysrq:Here is the list of possible values in /proc/sys/kernel/sysrq:
64 - enable signalling of processes (term, kill, oom-kill)
^^^^^^^^but enable_mask is not set in sysrq_moom_op.

Using "def_bool n" is pointless, simply using bool here appears more
appropriate.Further, retaining such options that don't have a prompt and aren't
selected by anything seems also at least questionable.Signed-off-by: Jan Beulich

Use the '%pF' format to get rid of an "#ifdef DEBUG" and make some printks
atomic.This removes the last in-tree uses of print_fn_descriptor_symbol(). I
marked print_fn_descriptor_symbol() deprecated and scheduled it for
removal next year to give time for out-of-tree modules to be updated.parisc's print_fn_descriptor_symbol() is currently broken there (it needs
to dereference the function pointer similar to ia64 and power). This
patch shouldn't make anything worse, but it means we need to fix
dereference_function_descriptor() instead of print_fn_descriptor_symbol()
to get meaningful initcall_debug output.Signed-off-by: Bjorn Helgaas

We shouldn't rely on "pnp_platform_devices" to tell us whether there
is a PNP RTC device.I introduced "pnp_platform_devices", but I think it was a mistake.
All it tells us is whether we found any PNPBIOS or PNPACPI devices.
Many machines have some PNP devices, but do not describe the RTC
via PNP. On those machines, we need to do the platform driver probe
to find the RTC.We should just register the PNP driver and see whether it claims anything.
If we don't find a PNP RTC, fall back to the platform driver probe.This (in conjunction with the arch/x86/kernel/rtc.c patch to add
a platform RTC device when PNP doesn't have one) should resolve
these issues:http://bugzilla.kernel.org/show_bug.cgi?id=11580

Author: Christian Borntraeger
hvc_console: rework setup to replace irq functions with callbacks
introduced a spinlock recursion problem. The notifier_del is
called with a lock held, and in turns calls free_irq which then
complains when manipulating procfs. This fixes it by moving the
call to the notifier to outside of the locked section.Signed-off-by: Christian Borntraeger

Once kernel configuration has CONFIG_HID turned on, let also all the
specialized drivers for quirky devices to be built (unless CONFIG_EMBEDDED is
specified), as usually users don't care that much which driver
gives them the functionality, but when they want generic support, they
probably want to have support for all the quirky devices as well.Signed-off-by: Jiri Kosina

Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.Signed-off-by: Anssi Hannula
