further comments on that report.
machine survived, and sysrq-m output was taken a few minutes after I (a)
noticed the oops and (b) installed the ksymoops RPM :) So the sysrq-m
is not from immediately after the oops.
I attach vmstat output from the alpha, running pre6. TAKE THIS OUTPUT
WITH A GRAIN OF SALT. I -think- the output starts when I start the rpm
build, and -think- the output stops when I noticed the oops. But the
possibility exists that I stopped the vmstat before the oom killer
kicked in.

Judging by your log it's not an OOM - page table corruption got caught by
do_wp_page(), which means that handle_mm_fault() fails (surprise, surprise),
which kills the process.
Looks like a massive memory corruption - later it fscked you in pte_alloc()
and then it screwed buffer cache lists.

I'm reinstalling now, with a bad blocks check, to make sure random disk
crap isn't affecting things. Disk is good AFAIK. Vaguely recent ATA-33
drive. I'll switch to the other alpha to see if I can see similar
symptoms.
Unfortunately I don't know of a good alpha memory tester like
memtest86. SRM firmware tests memory ok, but that probably doesn't mean
much.
Final comment before leaving this machine. Restarting the rpm-rebuilder
(post reboot and fsck), I still see a very large number of buffs. Since
there is zero swapped, this may or may not be normal. The cache value
appears sane, FWIW.

Bad disks won't cause the kind of page table corruption you saw - even if
the disk is total cr*p, and you have a swap partition on it, we never
actually put metadata in swap, only the actual user pages (some other
systems will page out the page directories too, Linux won't).
To me it actually looks like something corrupted a _big_ chunk of memory.
Which is not indicative of memory trouble either (sure, random one-bit
corruption can do just about anything, including causing a big memcpy to
go to the wrong place, but ..).
One thing that does things like this is missed TLB invalidates. Especially
on SMP. If you unmap and free a page, and user space still has a TLB entry
for it, you can have the kernel re-use the page at the same time user
space writes "garbage" to it.
This is, of course, a lot easier to trigger with MMU contexts and the
like.
Something like that is especially likely, as one of the values in your
oops is
swap_free: Bad swap file entry 2e66656464747368
where that value looks suspiciously like a likely string from a compiler:
"hstddef."
So I'd look very closely at the TLB invalidate code, or possibly try to
see if we might re-use a page for some other reason too early.

This isn't the oom killer - look more closely at your oops:
do_wp_page: bogus page at address 2000002dbc0 (page 0xfffffc173ab13b00)
VM: killing process cc1(29719)
Note the "do_wp_page" message _before_ the VM decided to kill the process.
And the first oops seems to be more of the same: big corruption in the
page tables.
Looks like the oom killer kicked in under extreme memory load, but the
extreme memory load caused something else too.
