test11-pre2

[Linus Torvalds]

Nothing stands out as affecting most people here. Security fix for /proc,
and various cleanups. Alpha and sparc fixes. If you use RAID or ramdisk,
upgrade. 

		Linus

-----

 - pre2:
    - Stephen Rothwell: directory notify could return with the lock held
    - Richard Henderson: CLOCKS_PER_SEC on alpha.
    - Jeff Garzik: ramfs and highmem: kmap() the page to clear it
    - Asit Mallick: enable the APIC in the official order
    - Neil Brown: avoid rd deadlock on io_request_lock by using a
      private rd-request function. This also avoids unnecessary
      request merging at this level.

    - Can-Ru Yeou: SiS301 fbcon driver
    - Andrew Morton: NMI oopser and kernel page fault punch through
      both console_lock and timerlist_lock to make sure it prints out..
    - Jeff Garzik: clean up "kmap()" return type (it returns a kernel
      virtual address, ie a "void *").
    - Jeff Garzik: network driver docs, various one-liners.
    - David Miller: add generic "special" flag to page flags, to be
      used by architectures as they see fit. Like keeping track of

So long as Linus can spell "sparc" correctly, I doubt David will
be offended.

Thanks for working on it but I am getting still:

Type  help  for more information
ok

Turning off software watchdog does not help, I am not sure if the "Watchdog
Reset" message is from the kernel though. I am using

make dep clean modules modules_install vmlinux ; gzip vmlinux

for compiling.

SPARCstation 10, 1 CPU, Fore 200e SBA, 64 MB RAM

I wonder if it could be my fault - could anybody testify that he was able to
boot any 2.4.0 on Sparc32?

Yup, SparcStation IPC, 48MB

What you are not seeing is probably the BUG() at bootmem.c:219. I can
almost bet it is related to the `holes' in your memory map,

> free_bootmem: base[0] size[1000000]
hole from 1000000 to 3fffffff
> free_bootmem: base[4000000] size[1000000]
hole from 5000000 to 7fffffff
> free_bootmem: base[8000000] size[1000000]

And when the zones are initialized, a test_and_set_bit goes wrong when
you hit the zone. To see the printk's during boot, change

arch/sparc/kernel/setup.c:48
- #undef PROM_DEBUG_CONSOLE
+ #define PROM_DEBUG_CONSOLE 1

I see... Is kernel v. 2.2 smarter in respect to holes? Various 2.2s boot with
all 64 MB without problems.

Done. But I got an idea to use mem=16mb and, yes, now it goes much farther -
but stops on serial ports:
