Subject: [PATCH 05/40] avr32: Use block_sigmask()

From: Matt Fleming <matt.fleming@...el.com>

Use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures.

In the past some architectures got this code wrong, so using this
helper function should stop that from happening again.
