Subject: this_cpu: Use this_cpu_ptr in crypto subsystem
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b44f4861f4cc1089424821f078d38441f8b4983;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

this_cpu: Use this_cpu_ptr in crypto subsystem

Just a slight optimization that removes one array lookup.
The processor number is needed for other things as well so the
get/put_cpu cannot be removed.
