Revert "x86/boot: Pull up cmdline preparation and early param parsing"
This reverts commit 8d48bf8206f77aa8687f0e241e901e5197e52423.
It turned out to be a bad idea as it broke supplying mem= cmdline
parameters due to parse_memopt() requiring preparatory work like setting
up the e820 table in e820__memory_setup() in order to be able to exclude
the range specified by mem=.
Pulling that up would've broken Xen PV again, see threads at
https://lkml.kernel.org/r/[email protected]
due to xen_memory_setup() needing the first reservations in
early_reserve_memory() - kernel and initrd - to have happened already.
This could be fixed again by having Xen do those reservations itself...
Long story short, revert this and do a simpler fix in a later patch.
