Subject: [IA64] Fix annoying IA64_TR_ALLOC_MAX message.
X-Git-Tag: upstream/snapshot3+hdmi~21860^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9894a4a3c7fb53258d46dafe9dd4f45369fd9dd;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[IA64] Fix annoying IA64_TR_ALLOC_MAX message.

Madison cpus support 64 TR registers.  Increase IA64_TR_ALLOC_MAX
to 64.  Also fixup the messages that get printed when this limit
is exceeded.  Repeating for every cpu is too noisy.
