[uClinux-dev] Using to RAM-area's
Hi all, my system has two seperated memory-area's. The first one lies in the area 0x1000 to 0x1040 (4 MB) and the other one lies in 0x2000 to 0x2040 (also 4 MB). Is there a way to make it possible to use both RAM-area's? I tried to tell it by the ATAG's, but the kernel didn't react to the second RAM-area. I'm using an ARM Cortex M4 with the 2.6.33 Kernel on uClinux-dist (20100315). Because of the paging-strategy, it should work in my opinion.

I think you are going to have to build your kernel with some minimal
debug info. Those values have no meaning to anyone unfortunately.
If the kernel was build with the symbols, you would get function names
printed instead which is much more helpful. It does make the kernel
slightly bigger, but not that much.
This is not the same as full debuging symbols though. Those would make
the kernel much larger.
CONFIG_FRAME_POINTER is really nice to have on.
Now it appears to be a warning.
Also kernel 2.6.x is not much more precise than just saying 'linux'.
2.6.x has been around for 7 or 8 years now.
Now the only warning in net/core/dst.c on current 2.6 code is:
void dst_release(struct dst_entry *dst)
{
if (dst) {
int newrefcnt;
smp_mb__before_atomic_dec();
newrefcnt = atomic_dec_return(&dst->__refcnt);
WARN_ON(newrefcnt < 0);
}
}
So that would mean something failed to keep track of the refcnt properly.
It may be that a buffer was freed and then reused after freeing.

This is from the file linux/arch/arm/mach-nds/arch.c.

[uClinux-dev] [PATCH] flthdr: improve default print due to no args
The current code misses checking a few args in order to determine the
default "print" mode (ktrace/l1stack/...). Rather than update a list
that people easily forget, rework the code to generically detect that
no arguments have been specified.
