sparc: Size mondo queues more sanely.

2011-08-16T01:31:41+00:00

[ Upstream commit 961f65fc41cdc1f9099a6075258816c0db98e390 ]

There is currently no upper limit on the mondo queue sizes we'll use,
which guarentees that we'll eventually his page allocation limits, and
thus allocation failures, due to MAX_ORDER.

Cap the sizes sanely, current limits are:

CPU  MONDO	2 * max_possible_cpus
DEV  MONDO	256 (basically NR_IRQS)
RES  MONDO	128
NRES MONDO	4

sparc: Access kernel TSB using physical addressing when possible.

2011-08-16T01:31:41+00:00

[ Upstream commit 9076d0e7e02b98f7a65df10d1956326c8d8ba61a ]

On sun4v this is basically required since we point the hypervisor and
the TSB walking hardware at these tables using physical addressing
too.

sparc: Minor tweaks to Niagara page copy/clear.

[ Upstream commit e95ade083939dcb4b0c51c1a2c8504ea9ef3d6ef ]

Don't use floating point on Niagara2, use the traditional
plain Niagara code instead.

Unroll Niagara loops to 128 bytes for copy, and 256 bytes
for clear.

sparc: Sanitize cpu feature detection and reporting.

2011-08-16T01:31:40+00:00

[ Upstream commit ac85fe8b21248054851e05bfaa352562e5b06dd3 ]

Instead of evaluating the cpu features for ELF_HWCAP every exec,
calculate it once at boot time.

Add AV_SPARC_* capability flag bits, compatible with what Solaris
reports to applications.

Report these capabilities once in the kernel log, and also via
/proc/cpuinfo in a new "cpucaps" entry.

If available, fetch the cpu features from the machine description
'hwcap-list' property of the 'cpu' node.
