[PATCH 0/2] x86/earlyprintk: setup earlyprintk as early as possible

[Alexander Kuleshov]

As setup_early_printk passed to the early_param, it will be usable only after
'parse_early_param' function will be called from the 'setup_arch'. So we have
earlyprintk during early boot and decompression. Next point after decompression
of the kernel where we can use early_printk is after call of the
'parse_early_param'.

This patch provides initialization of earlyprintk serial console as early
as possible in the arch/x86/kerne/head{32,64}.c
