These facilities are now available by default.
The config option makes no sense because:
1) It makes no change to the layout of any

2) It makes no significant change to code size,
only a handfull of lookup comparisons are
protected by the option.
3) It is needed for full RFC1812 compliance anyways.

[PATCH] device driver for the SGI system clock, mmtimer
SGI has been using this driver under Linux since 2001 but it was
never included in the upstream kernel. SuSE did include the patch for mmtimer
in SLES 9. The driver has been widely used for applications on the Altix
platform.
The timer hardware was designed around the multimedia timer specification by
Intel but to my knowledge only SGI has implemented that standard. The driver
was written by Jesse Barnes.
The second revision has interrupt support removed and was somewhat simplified
by removing one include file.

certain amount of "magic" the patch below looks for 8 byte windows first so

Currently metadata writing errors are ignored and not returned from
sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3.
Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method,
which in turn calls ->write_inode. ->write_inode method has void type, and
any IO errors happening inside are lost.
[PATCH] x86-64: sibling map fix for clustered mode
From: James Cleverdon
The value that cpuinfo returns for command 1 in ebx is the physical APIC ID
latched when the system comes out of reset.
Ordinarily, this is identical to the value in the local APIC's ID register,
because nearly all BIOSes accept the HW assigned value.
Our systems, made up of individual building blocks, can't do that. Each
node boots as a separate system and is joined together by the BIOS. Thus,
the BIOS rewrites the local APIC ID register with a new value.
Potomac and Nocona chips have a mechanism by which the BIOS writer can
change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the
thread ID. However, bits 4:3 are still those latched at reset. Oops!
Summary: Large clustered systems can't use cpuid to derive the sibling
information.
Fix: Use the local APIC ID. That's the value we use to online the CPUs, so
it had better be OK. For non-clustered systems, cpuid == local APIC, so
nothing but large boxes should be affected.
