When BenH and I were looking at the new code for handling 16G pages,
we noticed a small bug. It doesn't actually break anything user
visible, but it's certainly not the way things are supposed to be.
The 16G patches didn't update the huge_pte_offset() and
huge_pte_alloc() functions, which means th
This makes core_kernel_text() (and therefore kernel_text_address())
return the correct result. Currently all the __devinit routines (at
least) will not be considered to be kernel text.
This is just a quick fix for 2.6.27 - hopefully we will be able to fix
this better in 2.6.28.

Your analyse of ttys is very well. It was not my answer. All adresses in
system.map begin with 0xc... So I think it is the case for ttys too.

I'm not sure that is a failure. Why can't tty have value 0x5741 ?
I think the code in tty_io.c initialises driver->ttys and you shouldn't need to
do anything in your driver.
If you are not already aware, a useful way to explore kernel code is to use LXR:

Various changes to support QE USB Host on a MPC8360E-MDS board:
- Update the device tree per QE USB bindings;
- Configure QE Par IO;
- Set up BCSR for both USB Host and Peripheral modes;
- Add timer (GTM) node;
- Add gpio-controller node for BCSR13 bank;
- Select FSL_GTM, QE_GPIO and OF_SIMPLE_GPI
Hello all,
I have some trouble when trying to use gdb to debug a custom app.
That app crashes for no reason but always on the same spots (probably
hardware related, it runs on homebrew ppc-based card).
I've used gdb in the past, but always as part of 'bigger' IDEs.
So I run "gdb myapp" locally
I found where is the failure with your advices

Initialize this ?

Oh, do you mean the addresses vmalloc() returns are non-linear mappi
1. declaration of total_memory removed. Now including

2. is_power_of_2() works with u32 so I just inlined (size & (size-1)) != 0

Also this patch fixes default initialization: res->end should be 0x7fff
