So this hopefully continues closing various regressions, and most of the
changes are pretty small (ie diffstat shows a lot of oneliners). The
biggest patches are the trivial powerpc defconfig updates which show up
pretty clearly in the dirstat:
38.7% arch/powerpc/configs/
39.6% arch/powerpc/
42.9% arch/
2.4% drivers/ata/
7.6% drivers/block/
2.3% drivers/char/
2.0% drivers/message/fusion/
2.0% drivers/mmc/core/
4.1% drivers/net/
7.2% drivers/video/
38.0% drivers/
3.0% fs/hppfs/
7.8% fs/
2.8% kernel/
2.0% net/
ie if it weren't for those, the arch/ updates would hardly show up at all.
In the drivers, the two "big" changes are also totally trivial:
drivers/block/ shows up because of the ps2esdi driver removal (it's been
marked BROKEN for years), and drivers/video/ shows up because of a new
metronomefb.c driver for the E-Ink Metronome controller.
Apart from those, most of the changes really are fairly small and spread
out. The scheduler got some tweaking, the memstick driver got some TLC,
and cifs and reiserfs had some fixes.
The shortlog has more details, but it boils down to some reverts, some
docbook fixes, some sparse annotation fixups, a number of trivial patches,
and a healthy sprinkling of small fixups.
Give it a good testing, because we're hopefully now well on our way
towards that eventual real 2.6.25 release!

Hello,
cat /proc/<pid>/pagemap
and
cat /proc/<pid>/task/<pid>/pagemap
eats up to 100% of CPU while looping forever somewhere. On the other
hand on my old x86 the same commands take well below 1s so I
guess that is the expected behaviour.
PS. I'll be offline till tommorow just in case I was sent some patches to test.

And this one also worked. Now I have a nice clean dmesg :)

The patch below will speed this up for 32-bit processes but for 64-bit
ones it's still going to take a long time.
Cat'ing this file writes a 64-bit value for every possible page in the
task's address space, which for 64-bit is an enormous number of
entries.
This is not how this file is supposed to be used. Programs are
supposed to inspect /proc/${PID}/maps, and use those ranges to lseek()
around the pagemap file and fish out the values they need.
This expensive operation is quite harmless, the process can still be
killed, it is not unstoppable.

[SPARC64]: Define TASK_SIZE_OF()
This make "cat /proc/${PID}/pagemap" more efficient for

that's an open-coded get_cpu_var().
fwiw. Which isn't much, IMO. Sometimes it's nice to see things open-coded.

Good point, I might restructure that to use {get,put}_cpu_var().

I see. Sorry for the noise then 8-) I've got a couple of scripts for testing
/proc and /sys and I just noticed that some of processes started by them
would run for a couple hours eating 100% CPU which doesn't happen on other
arch'es I have around - hence my report. Thanks for clarification.

That's true.

This patch certainly helps in my case. Tested here:
sparc64 # time cat /proc/1/pagemap > /dev/null
real 0m0.046s
user 0m0.000s
sys 0m0.047s
Thanks,
Mariusz
