Where do I send a request of the following changes to linuxppc_2_4_devel:
in arch/ppc/Makefile:
add -D__powerpc__ to CPPFLAGS and CFLAGS (just like it is on kernel.org)
This makes drivers/char/serial.c compile correctly (no more 5 bit
characters)
in Makefile:
add -D__linux__ to CPPFLAGS
This makes coda.h compile correctly (u_quad_t)
in arch/ppc/kernel/i8259.c:
Some way to set
pci_intack = 0;
if we are running on a MVME 2400/2600, since the PIB (PCI-to-ISA Bridge)
does
not support anything but polling of the 8229 pair.
arch/ppc/platforms/prpmc800_setup.c:
patch previously sent.
I know that you think I have an incorrectly configured gcc, but I think
that it's a nice feature if the kernel compiles with a gcc that has been
configured according to the 'http://penguinppc.org/embedded/cross-compiling/
', even though it warns about gcc-3.x (3.2 generates working code with the
above changes)...

This is a handy one-liner for seeing what defines gcc has:
echo | powerpc-linux-gcc -E -dM -
When I run it with a cross-compiled gcc 2.95.3 *and* 3.2, I see both
#define __linux__ 1
#define __powerpc__ 1
The 2.95.3 was compiled with exactly the directions you refer to above.
3.2 was slightly different, but in both cases --target=powerpc-linux .

As Hollis has pointed out as well, it is very odd that you cannot get a
compiler which correctly defines __linux__ and __powerpc__. You are
creating a powerpc-linux cross compiler correct, and not powerpc-eabi or
some other incantation?

This is an issue since you're running the MVME 2400/2600 under
CONFIG_ALL_PPC, yes? Can you verify that in _devel, CONFIG_PPLUS works
on these boards, as from what I recall it should. As for fixing
CONFIG_ALL_PPC, what I intend to do is add a check to verify the bridge
and then set the intack occordingly.
