fix-rmmod-read-write-races-in-proc-entries.patch doesn't want dynamically
allocated ->proc_fops, because it will set it to NULL at module unload time.
Regardless of module status, switch to statically allocated ->proc_fops which
leads to simpler code without wrappers.
AFAICS, also fix the following bug: "sn_force_interrupt" proc entry set
->write for itself, but was created with 0444 permissions. Change to 0644.

Clean up of SGI SN partitioning related code.
The SN_SAL_GET_SN_INFO SAL call returns the partition ID, making
the SN_SAL_SYSCTL_PARTITION_GET SAL call redundant. Remove sn_partid
and use sn_partition_id.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
