I am wondering what we should do with this patch. The RCU stats display
the #s of RCU requests and actual updates on each CPU. On a normal system
they don't mean much to a sysadmin, so I am not sure if it is the right
thing to include this feature. OTOH, it is extremely useful to detect
potential memory leaks happening due to, say a CPU looping in
kernel (and RCU not happening consequently). Will a CONFIG_RCU_DEBUG
make it more palatable for mainline ?

Thanks
Dipankar

This comment looks stale; AIUI the behavior coded is what's desired.
This came up in a discussion with some implementors of a language
runtime about the cause of failures to open large files.

I was just looking over this and noticed 2.4.x makes u64 dma_addr_t
conditional on CONFIG_HIGHMEM64G where 2.5.x uses CONFIG_HIGHMEM. It's
clearly not necessary on CONFIG_HIGHMEM4G, hence this obvious (but
untested) patch:

Microscopic hugetlb cleanup: some variables static to hugetlbpage.c are
later declared as extern within a function in the same file. This patch
removes their declaration.

topology.h has a syntactic hygiene issue where it has a for () loop with
an if () in the body defined as a macro:

#define foo(...) for (...) if (...)

This patch prepares some of the bitop definitions used for the loop
mechanics to be usable in headers where BITS_PER_LONG is not guaranteed
to be defined for some reason. It removes the #ifdef on BITS_PER_LONG
in favor of if (sizeof(...) == ...) tests so hweight_long() will be
defined even when BITS_PER_LONG is not. unsigned long is also used for
some variables and/or return types that changed size with BITS_PER_LONG.
The 32-bit generic_hweight64() also changed its argument from a pointer
to a u64, which actually makes for a consistent interface in both cases.

The follow-up will make use of this to clean up the hygiene issue above
and correct a compilation error in topology.h

GRRR, neither seems to hurt my booting it or cause warnings but there
are two mistakes:

(1) not checking node < numnodes before !nr_cpus_node()
(2) casting the arg of generic_hweight32() to unsigned long is wrong

Fixed patch(es) below.

I'd find that useful - if it has a measurable overhead. If not, just leave
it on all the time ;-)

How about we just keep it floating about in the experimental kernels?
Can't say that I use it for anything, really.

2.5.69-mm3 bug

[Szonyi Calin]

[-- Attachment #1: Type: text/plain, Size: 650 bytes --]

Hello

With 2.5.69-mm3
<0> Kernel panic: Fatal exception in interrupt.In interrupt handler - not
syncing.

I couldn't put the hole message because it's bigger than the screen size.

This happens when running killall5 in the shutdown (rc.6) script

I'll try to boot with console lp0 and see if I can get it on printer

Config and programs version attached. Kernel compiled with gcc-3.2.3
but happens even when compiled with gcc-2.95.3

Are there similar things, inplace or in patches? Perhaps a menu section
for kernel metrics and a nice little niche in /proc to display them?
Things like this are helpful when tuning a kernel, but perhaps not wanted
for the minimalist (like embedded) configs.
