Matt Macy eb7c901995 hwpmc: simplify calling convention for hwpmc interrupt handling 
pmc_process_interrupt takes 5 arguments when only 3 are needed.
cpu is always available in curcpu and inuserspace can always be
derived from the passed trapframe.

While facially a reasonable cleanup this change was motivated
by the need to workaround a compiler bug.

core2_intr(cpu, tf) ->
  pmc_process_interrupt(cpu, ring, pmc, tf, inuserspace) ->
    pmc_add_sample(cpu, ring, pm, tf, inuserspace)

In the process of optimizing the tail call the tf pointer was getting
clobbered:

(kgdb) up
1205                    error = pmc_process_interrupt(cpu, PMC_HR, pm, tf,

resulting in a crash in pmc_save_kernel_callchain.
