When introducing support for DABRX in 4474ef0, we broke older 32-bit CPUs
that don't have that register.
Some CPUs have a DABR but not DABRX. Configuration are:
- No 32bit CPUs have DABRX but some have DABR.
- POWER4+ and below have the DABR but no DABRX.
- 970 and POWER5 and above have DABR and DABRX.
- POWER8 has DAWR, hence no DABRX.
This introduces CPU_FTR_DABRX and sets it on appropriate CPUs. We use
the top 64 bits for CPU FTR bits since only 64 bit CPUs have this.
Processors that don't have the DABRX will still work as they will fall
back to software filtering these breakpoints via perf_exclude_event().

POWER8 can take a denormalisation exception on any VSX registers.
This does the extra 32 VSX registers we don't currently handle.

The following simplifies the denorm code by using macros to generate the long
stream of almost identical instructions.
This patch results in no changes to the output binary, but removes a lot of
lines of code.

In 2ac6f42 powerpc/cputable: Fix oprofile_cpu_type on power8
we broke all power8 hw events.
This reverts this change and uses oprofile_type instead. Perf now works
on POWER8 again and oprofile will revert to using timers on POWER8.
Kudos to mpe this fix.

RTAS token "ibm,get-config-addr-info" or ibm,get-config-addr-info2"
are used to retrieve the PE address according to PCI address, which
made up of domain/bus/slot/function. If we don't have those 2 tokens,
the domain/bus/slot/function would be used as the address for EEH
RTAS operations. Some older f/w might not have those 2 tokens and
that blocks the EEH functionality to be initialized. It was introduced
by commit e2af155c ("powerpc/eeh: pseries platform EEH initialization").
The patch skips the check on those 2 tokens so we can bring up EEH
functionality successfully. And domain/bus/slot/function will be
used as address for EEH RTAS operations.

pcibios_fixup_resources
If a BAR has the value of 0, we would assume that it is unset yet and
then mark the resource as unset and would reassign it later. But after
commit 6c5705fe (powerpc/PCI: get rid of device resource fixups)
the pcibios_fixup_resources is invoked after the bus address was
translated to linux resource. So the value of res->start is resource
address. And since the resource and bus address may be different, we
should translate it to the bus address before doing the check.

The internal crtc cursor gem object pointer was never set/updated since
it was required to be set in the first place.
Fixing this will make the pin/unpin count match and prevent cursor
objects from leaking when userspace drops all references to it. Also
make sure we drop the gem obj reference on failure.
This patch only affects Cedarview chips.

The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix

The console's clocks are disabled after the uart driver is probed.
It makes that we can see less log from the console now
(though we still can get all the log by the `dmesg`).
So enable the clocks for console, and we can see all the log again.
This patch also disables the sport->clk_per when we fail to enable
the sport->clk_ipg;
