New Revision: 265020
URL: http://svnweb.freebsd.org/changeset/base/265020
Log:
Remove cpu_idcache_wbinv_all() from kdb_cpu_trap(), it's no longer needed.
This was added ca. 2004 for the purpose of ensuring the caches were in the
right state after the debugger set a breakpoint. kdb_cpu_sync_icache()
was added in 2007 to handle that situation, and now the wbinv_all is
actually harmful because the operation isn't broadcast to other cores.
