* vmscan: kswapd: don't retry balance_pgdat() if all zones are unreclaimableKOSAKI Motohiro2010-01-16
| | | | | | | | | | | | | | | | | | | Commit f50de2d3 (vmscan: have kswapd sleep for a short interval and double check it should be asleep) can cause kswapd to enter an infinite loop if running on a single-CPU system. If all zones are unreclaimble, sleeping_prematurely return 1 and kswapd will call balance_pgdat() again. but it's totally meaningless, balance_pgdat() doesn't anything against unreclaimable zone!

* smp_call_function_any(): pass the node value to cpumask_of_node()David John2010-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | The change in acpi_cpufreq to use smp_call_function_any causes a warning when it is called since the function erroneously passes the cpu id to cpumask_of_node rather than the node that the cpu is on.

* kernel.h: add BUILD_BUG_ON_NOT_POWER_OF_2()Roland Dreier2010-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add BUILD_BUG_ON_NOT_POWER_OF_2() When code relies on a constant being a power of 2: #define FOO 512 /* must be a power of 2 */ it would be nice to be able to do: BUILD_BUG_ON(!is_power_of_2(FOO)); However applying an inline function does not result in a compile-time constant that can be used with BUILD_BUG_ON(), so trying that gives results in: error: bit-field '<anonymous>' width not an integer constant As suggested by akpm, rather than monkeying around with is_power_of_2() and risking gcc warts about constant expressions, just create a macro BUILD_BUG_ON_NOT_POWER_OF_2() to encapsulate this common requirement.

* kfifo: sanitize *_user error handlingAndi Kleen2010-01-16
| | | | | | | | | | | | | | | | | | | | | | | | Right now for kfifo_*_user it's not easily possible to distingush between a user copy failing and the FIFO not containing enough data. The problem is that both conditions are multiplexed into the same return code. Avoid this by moving the "copy length" into a separate output parameter and only return 0/-EFAULT in the main return value. I didn't fully adapt the weird "record" variants, those seem to be unused anyways and were rather messy (should they be just removed?) I would appreciate some double checking if I did all the conversions correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we setup buffer for display plane, we'll check any pending required GPU flush and possible make interruptible wait for flush complete. But that wait would be most possibly to fail in case of signals received for X process, which will then fail modeset process and put display engine in unconsistent state. The result could be blank screen or CPU hang, and DDX driver would always turn on outputs DPMS after whatever modeset fails or not. So this one creates new helper for setup display plane buffer, and when needing flush using uninterruptible wait for that. This one should fix bug like https://bugs.freedesktop.org/show_bug.cgi?id=24009. Also fixing mode switch stress test on Ironlake.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For any given clock we can use the find_pll to get the corresponding DPLL setting. It is unnecessary to use the find_reduce_pll callback function to calculate the DPLL parameter for LVDS downclock in order to get the same divider factor(P) for the normal and downclock. In theory when the LVDS downclock is supported by LVDS panel, we should get the same DPLL divider factor(P) for the normal clock and reduced downclock. If we get the diferent divider factor(P) for normal clock and reduced downclock, it means that the found downclock is incorrect and should be discarded. So we should use find_pll callback to calculate the DPLL parameter for the LVDS reduced downclock as for the normal clock. Then we can do the cleanup about find_reduced_pll.

| | | | | | | | | | | | | | | | | | | | | | | | The HP comaq nx9020/Samsung SX20S laptop always report that the LID status is closed and we can't use it reliabily for LVDS detection.

Unfortunately it does not work well for 32-bit applications running on 64-bit kernels since applications expect that number is "worth" only 32 bits when kernel advances by 64 bits. Fix that by ensuring that output produced for compat tasks uses 32-bit units. Reported-and-tested-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

During probe, psmouse_switch_protocol() calls psmouse_extensions() with set_properties=1. This calls the dummy synaptics_init() which returns an error code, instructing us not to use the synaptics extensions. During resume, psmouse_reconnect() calls psmouse_extensions() with set_properties=0, in which case call to synaptics_init() is bypassed and PSMOUSE_SYNAPTICS is returned. Since the result is different from previous attempt psmouse_reconnect() fails and full re-probe happens. Fix this by tweaking the set_properties=0 codepath in psmouse_extensions() to be more careful about offering PSMOUSE_SYNAPTICS extensions.
