MFP4:
- pmcstat(8) gprof output mode fixes: lib/libpmc/pmclog.{c,h}, sys/sys/pmclog.h: + Add a 'is_usermode' field to the PMCLOG_PCSAMPLE event + Add an 'entryaddr' field to the PMCLOG_PROCEXEC event, so that pmcstat(8) can determine where the runtime loader /libexec/ld-elf.so.1 is getting loaded. sys/kern/kern_exec.c: + Use a local struct to group the entry address of the image being exec()'ed and the process credential changed flag to the exec handling hook inside hwpmc(4). usr.sbin/pmcstat/*: + Support "-k kernelpath", "-D sampledir". + Implement the ELF bits of 'gmon.out' profile generation in a new file "pmcstat_log.c". Move all log related functions to this file. + Move local definitions and prototypes to "pmcstat.h" - Other bug fixes: + lib/libpmc/pmclog.c: correctly handle EOF in pmclog_read(). + sys/dev/hwpmc_mod.c: unconditionally log a PROCEXIT event to all attached PMCs when a process exits. + sys/sys/pmc.h: correct a function prototype. + Improve usage checks in pmcstat(8).
