commit 8c6a98b22b750c9eb52653ba643faa17db8d3881 upstream.
Currently sysrq_enabled and __sysrq_enabled are initialised separately
and inconsistently, leading to sysrq being actually enabled by reported
as not enabled in sysfs. The first change to the sysfs configurable
synchronises these two:
static int __read_mostly sysrq_enabled = 1;
static int __sysrq_enabled;
Add a common define to carry the default for these preventing them becoming
out of sync again. Default this to 1 to mirror previous behaviour.

commit 7ab7b5adfb923978a2cab7bd3fac9ccf7d21cc3f upstream.
Internally 'disable' the filter when re-injecting Alt-SysRq instead
of relying on input core to suppress delivery of injected events
to the originating handler.
This allows to revert commit 5fdbe44d033d059cc56c2803e6b4dbd8cb4e5e39
which causes problems with existing userspace programs trying to
loopback the events via evdev.

The tty code should be in its own subdirectory and not in the char
driver with all of the cruft that is currently there.
