avr32: don't mask signals in the error path

The current handle_signal() implementation is broken - it will mask
signals if we fail to setup the signal stack frame, which isn't the
desired behaviour, we should only be masking signals if we succeed in
setting up the stack frame.  It looks like this code was copied from the
old (broken) arm implementation but wasn't updated when the arm code was
fixed in commit a6c61e9dfdd0 ("[ARM] 3168/1: Update ARM signal delivery
and masking").

function, which used to be the trigger to make umem start to work.

We need to implement unplugging to make umem start to work, or I/O

acerhdf: lowered default temp fanon/fanoff values

Due to new supported hardware, of which the actual temperature limits of
processor, harddisk and other components are unknown, it feels safer with
lower fanon / fanoff settings.

It won't change much for most people, already using acerhdf, as they use
their own fanon/fanoff variable settings when loading the module.

Furthermore seems like kernel and userspace tools have been improved to
work more efficient and netbooks don't get so hot anymore.

ext4: fix handling of journalled quota options

Commit 26092bf5 broke handling of journalled quota mount options by
trying to parse argument of every mount option as a number.  Fix this
by dealing with the quota options before we call match_int().
