This allows us to run on hardware configurations for which the
ITC has non-uniform frequencies across CPUs.
While here, change the clock XIV to type IPI so as to protect
the interrupt delivery against CPU re-balancing once that's
implemented.

remote tape service returns deliberately crafted packets containing
more data than requested.
Fix this by checking the returned amount of data and bail out when it
is more than what we requested.

by which segment contains the program entry point. This affects
obreak() and is required for correct operation of that function
on 64-bit PowerPC systems. The previous behavior was apparently
required only for the Alpha, which is no longer supported.

enabled. Basically most of the operations were incorrect causing
bad sacks when you enabled nr-sack. The fixes range across
4 files and unifiy most of the processing so that we only test
nr_sack flags to decide which type of sack to generate.
Optimization left for this is to combine the sack generation
code and make it capable of generating either sack thus shrinking
out a routine.

to return SNMP_ERR_NOSUCHNAME for ALTQ objects, if ALTQ is disabled, so that the agent
