Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.Reported-and-tested-by: Hernando Torque

This reverts commit 5fdbe44d033d059cc56c2803e6b4dbd8cb4e5e39.
Apparently there exist userspace programs that expect to be able to
"loop back" and distribute to readers events written into
/dev/input/eventX and this change made for the benefit of SysRq
handler broke them. Now that SysRq uses alternative method to suppress
filtering of the events it re-injects we can safely revert this change.Reported-by: Kristen Carlson Accardi

When rebinding a serio driver via sysfs drvctl interface it is
possible for an interrupt to trigger after the disconnect of the
existing driver and before the binding of the new driver. This will
cause the serio interrupt handler to queue a rescan event which will
disconnect the new driver immediately after it is attached.This change removes pending rescans from the serio event queue after
processing the drvctl request but before releasing the serio mutex.Reproduction involves issuing a rebind of device port from psmouse
driver to serio_raw driver while generating input to trigger
interrupts. Then checking to see if the corresponding
i8042/serio4/driver is correctly attached to the serio_raw driver
instead of psmouse.Signed-off-by: Duncan Laurie

Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.Signed-off-by: Ping Cheng

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar
