Subject: [PATCH v2 0/4] Optimise cache-flushing system call
Message-ID: <1369395087-30972-1-git-send-email-will.deacon@arm.com>

Hi guys,

This is a follow-on from the patches I originally posted here:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2013-March/157810.html

but with some notable differences:

  - I've temporarily dropped the iovec system call while I try to work
    out a sane threshold value between flushing by line and nuking L1.

  - Added syscall restarting to address DoS issues raised by Catalin.

  - Added access_ok check now that vma searching code is removed.

  - Based on 3.10-rc2.

As per usual, all comments are welcome.

Cheers,

Will
