The patch titled
Subject: S390: use block_sigmask()
has been removed from the -mm tree. Its filename was
s390-use-block_sigmask.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

From: Matt Fleming <matt.fleming@xxxxxxxxx>
Subject: S390: use block_sigmask()
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.
