Subject: [PATCH 0/2] Fixes for system freezes for r8188eu 

The driver issues "scheduling while atomic" messages and will freeze the
system. These problems are due to attempting to dynamically load library
encryption routines from a tasklet. The fixes are relatively simple. All
that is needed is to replace indirect calls of the try_then_request_module()
macro with a direct call to lib80211_get_crypto_ops(), which forces a load
of the lib80211 module when the wifi driver is loaded.

There will be a similar patch for TKIP encryption; however, the faulty
patch has already been reverted, thus a fix to use the lib80211 routine
directly will be more intrusive. My original attempt failed, thus I am
delaying that fix.
