This patch fixes the following problems: - Problem with the Memory Channel API whereby the function imc_asalloc did not allow a negative key (most significant bit of key being set). - Problem that caused mcm_init to core dump when resolver fails on system boot. - Fixes a problem in which a resolver failure produces an unhelpful error message from mcm_init on boot. - Fixes a problem with the Memory Channel API whereby the function imc_ckerrcnt was signifying an error had occured when in fact no error had occurred. The following is the error code seen when running an MPI code: [5]MPI Die-ump2chck.c 91 "ump_wait failure" (-16)
