hvc_xen: Remove unnecessary __GFP_ZERO from kzalloc (2013-08-30 14:11:28
-0700)
----------------------------------------------------------------
TTY/Serial driver patches for 3.12-rc1
Here's the big tty/serial driver pull request for 3.12-rc1.
Lots of n_tty reworks to resolve some very long-standing issues, removing the
3-4 different locks that were taken for every character. This code has been
beaten on for a long time in linux-next with no reported regressions.
Other than that, a range of serial and tty driver updates and revisions. Full
details in the shortlog.
