2007-05-08use mutex instead of semaphore in virtual console driverMatthias Kaehlcke
The virtual console driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore. Signed-off-by: Matthias Kaehlcke <matthias.kaehlcke@gmail.com> Cc: "Antonino A.

2007-05-08vt: expose system-wide UTF-8 default setting via sysfsAntonino A. Daplas
Create a variable, default_utf8, that defines the system-wide default UTF-8 setting. This variable can be altered via sysfs. If the variable is properly set, this should mimimize breakage of UTF-8 encoded consoles when doing a reset or echo -e '\033c' and of newly opened/allocated consoles. This is based from patches by Jan Engelhardt and Paul LeoNerd Evans.

2007-05-08vt: allow for the palette to be exposed and changed via sysfsJan Engelhardt
Allow for the palette to be exposed and changed via sysfs. A call to /usr/bin/reset will slurp the new definitions in for the current console.

2007-05-08tpm: fix sleep-in-spinlockParag Warudkar
flush_scheduled_work() can sleep, and we're calling it under spinlock. AFAICS, moving flush_scheduled_work before spin_lock() should not cause any problems. Reason being - The only thing that can race against tpm_release is tpm_open (tpm_release is called when last reference to the file is closed and only thing that can happen after that is tpm_open??) and tpm_open acquires driver_lock and more over it bails out with EBUSY if chip->num_opens is greater than 0. I also moved chip->num_pending-- to after deleting timer and setting data pending as it looks more correct for the paranoid although it probably doesn't matter as it is guarded by driver_lock. None the less this change should not cause problems. While I was at it I noticed a missing NULL check in tpm_register_hardware which is fixed with this patch as well.
