powerpc: Add DSCR FSCR register bit definition

2013-03-05T05:56:30+00:00

This sets the DSCR (Data Stream Control Register) in the FSCR (Facility Status
& Control Register).

Also harmonise TAR (Target Address Register) FSCR bit definition too.

powerpc: Add helper functions for transactional memory context switching

2013-02-15T05:58:52+00:00

Here we add the helper functions to be used when context switching.  These
allow us to fully reclaim and recheckpoint a transaction.

We introduce a new paca field called tm_scratch to help us store away register
values when doing the low level tm reclaim register save.

powerpc: Add support for context switching the TAR register

2013-02-08T03:05:50+00:00

This patch adds support for enabling and context switching the Target
Address Register in Power8. The TAR is a new special purpose register
that can be used for computed branches with the bctar[l] (branch
conditional to TAR) instruction in the same manner as the count and link
registers.

powerpc: Hardware breakpoints rewrite to handle non DABR breakpoint registers

2013-01-10T06:01:44+00:00

This is a rewrite so that we don't assume we are using the DABR throughout the
code.  We now use the arch_hw_breakpoint to store the breakpoint in a generic
manner in the thread_struct, rather than storing the raw DABR value.

The ptrace GET/SET_DEBUGREG interface currently passes the raw DABR in from
userspace.  We keep this functionality, so that future changes (like the POWER8
DAWR), will still fake the DABR to userspace.
