* Merge branch 'for-linus' of ↵Linus Torvalds2011-03-04

| * Blackfin: iflush: update anomaly 05000491 workaroundMike Frysinger2011-03-04
| | | | | | | | | | | | Recent feedback from design says we need three NOPs in the hardware loop. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | Some devices will use the outs* funcs with a length of zero, so make sure we do not write any data in that case. Reported-by: Gilbert Inho <gneny@edevice.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This resolves a problem seen when using the Android dynamic linker. Sometimes the dynamic linker would seg-fault at start up and this was eventually traced to the handling of a COW fault for a page which was being modified by the linker. If there was no cache aliasing between the kernel and the user page, the page was not flushed, leaving the newly copied data in the D-cache. However when executing instructions from that page, the I-cache is filled directly from external memory, rather than the D-cache, and causing garbage to be executed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A strange variation was seen in the BogoMIPS figure for the ST40-300.

Modern Linux should generally get exactly the states it requests. In particular, when a CPU is taken off-line, it must not be demoted, else it can prevent the entire package from reaching deep C-states. https://bugzilla.kernel.org/show_bug.cgi?id=25252 Signed-off-by: Len Brown <len.brown@intel.com>
