parisc is one of the few architectures that does not call
parse_early_param() from setup_arch(). That was mostly harmless until
commit d49004c5f0 ("arch, mm: consolidate initialization of nodes,
zones and memory map") moved the consumer of several hugetlb command
line parameters into mm_core_init_early(), which runs before the
generic parse_early_param() call in start_kernel().
As a result hugepages=, hugepagesz=, default_hugepagesz=, hugetlb_cma=
and hugetlb_free_vmemmap= are recorded after they have already been
consumed and are silently dropped on parisc.
Call parse_early_param() from setup_arch(), after the command line has
been set up and the memory inventory has been taken. jump_label_init()
must be called first because early parameter handlers may enable or
disable static keys. Both functions are safe to call more than once:
the generic calls in start_kernel() remain in place and turn into no-ops.
