cpu_dumpconf() is the machine-dependent interface
invoked during system bootstrap to determine the dump device and initialize
machine-dependent kernel core dump state. Internally,
cpu_dumpconf() will invoke
cpu_dumpsize() to calculate the size of
machine-dependent kernel core dump headers.
dumpsys() is invoked by
cpu_reboot() to dump kernel physical memory onto the
dump device. dumpsys() invokes
cpu_dump() to write the machine-dependent header to
the dump device at block number *blknop using the dump
device's PIO dump routine specified by the dump
argument.
cpu_dumpsize(),
cpu_dump(), and dumpsys()
are parts of the machine-dependent interface, however they are not exported
to machine-independent code.
