this is the newest x86 SMP patchset (attached), against 2.3.99-pre5. The
patch is also available from:
http://www.redhat.com/~mingo/smp-x86-patches/smp-2.3.99-5-B2
Changes:
- external APIC (82489DX) code rewrite, default configuration handling
rewrite and fixes (Maciej W. Rozycki, tested by Eric Gilmore)
- support for i486 SMP boxes [yeah! :-)] (Maciej W. Rozycki)
- various fixes and cleanups (Maciej W. Rozycki, me)
- fixed CPU/process stats in UP-IOAPIC mode, first reported by Gabor Vitez
(me)
some small unrelated x86 items:
- added the string-i486.h assembly version of strstr to asm-i386/string.h
because it's much faster than the lib/ version. (me)
- added mem=exactmap option to enable setting of an exact e820 memory map,
as specified by the user. Right now the kernel adds an unconditional
low-RAM e820 region if mem= is added. (me)
with this patch applied the x86 SMP/APIC subsystem is again in 'no known
bugs' status - please resend reports to me if any problem is still
unfixed, or any new problem arises. The patch has been sanity booted on
8-way, dual, UP-IOAPIC and UP (486) systems.
