System calls with an unsigned long long argument can't be converted with
the standard wrappers since that would include a cast to long, which in
turn means that we would lose the upper 32 bit on 32 bit architectures.
Also semctl can't use the standard wrapper since it has a 'union'
parameter.
So we handle them as special case and add some extra wrappers instead.

This enables the use of syscall wrappers to do proper sign extension
for 64-bit programs.

By selecting HAVE_SYSCALL_WRAPPERS architectures can activate
system call wrappers in order to sign extend system call arguments.
All architectures where the ABI defines that the caller of a function
has to perform sign extension probably need this.

Not a single architecture has wired up sys_pselect7 plus it is the
only system call with seven parameters. Just make it static and
rename it to do_pselect which will do the work for sys_pselect6.

Remove __attribute__((weak)) from common code sys_pipe implemantation.
IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations
with the same name. Just rename them.
For sys_pipe2 there is no architecture specific implementation.

Convert all system calls to return a long. This should be a NOP since all
converted types should have the same size anyway.
With the exception of sys_exit_group which returned void. But that doesn't
matter since the system call doesn't return.

The Logitech QuickCam Pro 9000 does not appear to any product identification
strings in its USB device descriptor. Therefore it receives a device name of
"USB Device 0x46d:0x990". Th e attached patch below adds a USB quirk to
provide a more friendly name.

Resetting HP pinctl at the unplugged state may cause a sort of regression
on some devices because of their wrong pin configuration.
A simple workaround is to disable the pin reset. This is ugly and may be
not good from the power-saving POV (if any), but damn simple.

CF-74 does the headphone/speaker switching on hardware, thus the driver
shouldn't do any software-toggling of pins. Otherwise it results in a
silent headphone output.
This patch simply resets the hp_detect flag to fix the problem.
