The reason why we link proc_info_list in ".rodata" section is that
it context should never be modified.
This patch also renames ".init.proc.info" section to ".p

Regressions :-(
Tests which did not succeed and are blocking,
including tests which could not be run:
test-amd64-amd64-pygrub 7 xen-boot fail REGR. vs. 130155
build-armhf
The code in viridian_synic_wrmsr() duplicates logic in vlapic_reg_write()
to update the ICR, ICR2 and TASKPRI registers. Instead of doing this,
make vlapic_reg_write() non-static and call it.
