I threw a printk() into mce_gen_pool_init() and got:
[ 2.948285] mce: mce_gen_pool_init: num_possible_cpus = 144
So it is currently true that number of CPUs has been computed at this point.
So using memblock_alloc() based on number of CPUs may work

I use "git send-email" to send out patches, and usually "b4" to get them
to my desktop. I do have "mutt" on there, but IT have made it complex
for me to use it to simply read & reply. It requires separate mutt config
files to fetch mail and a different config to send mail because of the
firewall rules on the lab where my desktop lives.
