The Linux/Alpha FAQ, the unix-ag LX164 overview, the Rawhide install
HOWTO and the Ruffian FAQ are all gone. Point the "Alpha system type"
help at the system and motherboard lists on the alphalinux.org wiki
instead, give LX164 a one-line description in place of its link, and
drop the others.

Fix the system lists in the "Alpha system type" choice and the platform
help texts, cross-checked against the alphalinux.org wiki and the
kernel sources:
- There is no AlphaServer GS40 or DS10E. Wildfire also shipped with
EV68 (21264C) CPUs.
- "AS" means AlphaServer elsewhere in the list, but the Alcor "AS 600,
AS 500" are AlphaStations, as is the Noritake "AlphaServer 600A".
- Takara is 21164-based, not "11164".
- Linux 6.10 dropped support for CPUs before EV56, which took the
AlphaStation 600 and Alpha XL 300 with it. Say once that EV56 or
later is required rather than qualifying every entry.
- Add systems missing from their entries: the UP1500 (Nautilus), DS15
and TS202c (Titan), Digital Server 3300 (Noritake), Digital Server
5300 and 7300 (Rawhide), and the Ruffian boards in place of
"Samsung APC164UX".
- Add Eiger, Nautilus and RX164 to the summary list and help text to
PC164, RX164, SX164 and Shark, which had none. Note that the Ruffian
and RX164 boards have no SRM console.
Also drop the Jensen and EV4/EV5 references removed in 6.10, and the
claim that SRM cannot boot from IDE, which is not true of SRM in
general. NR_CPUS can be set to 32 on any platform, so say what the
hardware supports instead of implying a per-platform kernel limit.

The AlphaServer GS320 has up to 32 CPUs and the Wildfire code handles
all eight QBBs, but a Wildfire-only kernel defaults to NR_CPUS=4 and
ignores the rest unless the user raises it by hand.

Nice cleanup work!
I applied the series cleanly to my for-next branch and build-tested
every commit with the Alpha defconfig. I also built the final tree
with these configurations:
Generic SMP, NR_CPUS=32
Wildfire SMP, NR_CPUS=32
Wildfire SMP, explicit NR_CPUS=4
Wildfire with SMP disabled
Marvel SMP, NR_CPUS=32
DP264 SMP, NR_CPUS=4
