Subject[PATCH] SMP parsing rewrite, phase 1
Hi all,

The below patch against 2.5.59 is also available from
ftp://ftp.kernel.org/pub/linux/kernel/people/grover/ ,
or bk pull http://linux-acpi.bkbits.net/linux-smp-init .

Before I spent any more time carving up mpparse.c, I just wanted to have
the chance for feedback from others.

This patch begins to draw a distinction between the structure of the MPS
table's items, and the kernel's internal data structures. Previously, it
made sense to just use MPS format throughout, but with the introduction of
a second method to enumerate CPUs, IOAPICs etc. on x86 (i.e. ACPI), this
really is no longer ideal. A clean, minimal interface for ACPI and MPS to
report discovered resources will cut down on cross-module dependencies,
shared global arrays, and will probably even reduce the kernel image
somewhat.

See below for more detail, but to sum up, I:
1) Renamed MPS-specific structs starting with "mpc_" to "mps_", to reflect
their actual purpose.
2) Do the same thing for variables.
3) Created arch/i386/kernel/smpenum.c, for the enum-method-neutral APIs.
To begin with, I have only implemented the new interface to replace
MP_processor_info - the others will be done in a similar manner.
4) An unrelated ACPI init changeset sneaked in, sorry :)

It's been tested on my machine in ACPI and MPS mode - obviously some more
testing coverage would be nice.

Comments?

Thanks -- Regards -- Andy

[smpenum] Fixes for numaq and summit

<agrover@groveronline.com> (03/01/15 1.879.92.5)
[smpenum] Replace MP_processor_info with a non-MPS-specific equivalent

Remove now-obsolete MP_processor_info function from mpparse.c
Rename mps_read_mpc -> mps_parse_table
Remove unneeded includes in smpenum.c
Bring over more variables from mpparse.c
Implement smp_processor_register(). This function takes the place of
MP_processor_info, but does not use MPS data structures.
Change mpc_apic_id's printk to account for the removal of
nonessential items from struct mpc_config_processor.
Add include of smpenum.h in smp.h
Remove nonessential fields from mpc_config_processor

<agrover@groveronline.com> (03/01/14 1.879.92.4)
[smpenum] structs beginning with "mpc_" are actually MPS-specific.
Rename
structs to "mps_" to facilitate the creation of different "mpc_" struct
definitions.

Create smpenum.[ch], where all the enumeration-method-neutral code will
go, and start moving some arrays there, for now.

<agrover@groveronline.com> (03/01/14 1.879.92.3)
[mpparse] more smp -> mps renames

<agrover@groveronline.com> (03/01/14 1.879.92.2)
[mpparse] Rename smp* things in mpparse.c that are actually
MPS-specific (not SMP-specific) to mps*, including get_mps_config and
found_mps_config.

<agrover@groveronline.com> (03/01/14 1.838.62.2)
[mpparse] "smp" should only be used in non-ACPI or non-MPS-specific
code. so, start to make that distinction clear
