SAMA7G5 has different masks for chip ID and chip version on CIDR
register compared to previous AT91 SoCs. For this the commit adapts
the code for SAMA7G5 addition by introducing 2 new members in

powerpc/32s: move DABR match out of handle_page_fault
handle_page_fault() has some code dedicated to book3s/32 to
call do_break() when the DSI is a DABR match.
On other platforms, do_break() is handled separately.
Do the same for book3s/32, do it earlier in the process of DSI.

This series is a first step on the way to C syscall/exception entry/exit.

It takes benefit of the removal of traps

callers ignored the return value already before.
This simplifies the next patch.

Hi Corey,
Could you help to review this patch to kcs_bmc_aspeed.c?
It mainly fixes the register layout/offsets of Aspeed LPC controller.
Thanks,
Chiawei

On 40x and 8xx, kernel text is pinned.
On book3s/32, kernel text is mapped by BATs.
Enable instruction translation at the same time as data translation, it
makes things simpler.
In syscall handler, MSR_RI can also be set at the same time because
srr0/srr1 are already saved and r1 is set
msr argument is not used anymore, remove it.

If the code can use a stack in vm area, it can also use a
stack in linear space.
Simplify code by removing old non VMAP stack code on PPC32.
That means the data translation is now re-enabled early in
exception prolog in all cases, not only when using VMAP stacks.

40x MSR value doesn't fit on 15 bits.
LOAD_REG_IMMEDIATE() in places that will be used also
with 40x in the next patch.

Change CRITICAL_EXCEPTION_PROLOG macro to a gas macro to
remove the ugly ; and \ on each line.
