[uml-devel] uml-2.6.8-rc2 (2.6.8-rc2 w/ uml-patch-2.6.7-01)

["gboutwel" <gboutwel@praize.com>]

  I'm testing the 2.6.8 waters. Looks like it's not been included

in the rc2 version yet. It's in the mm1 version though... so

there's hope. Here's what I've done:



1) tar jzf linux-2.6.7.tar.bz2



2) mv linux-2.6.7 linux-2.6.8-rc2-1um



3) bzcat patch-2.6.8-rc2.bz2 | patch -p1



4) bzcat uml-patch-2.6.7-01.bz2 | patch -p1 --dry-run | less



* not bad, just shows 1 reject, which is the removal of an

#include from init_setup.c



5) cp ~/2.6.7/config-2.6.7-1um .config



6) make oldconfig ARCH=um



7) make linux ARCH=um



* this fails on arch/um/drivers/stdio_console.c with:

arch/um/drivers/stdio_console.c:207: error: conflicting types

for `console_device'

include/linux/console.h:107: error: previous declaration of `console_device'



Where:



include/linux/console.h:107 extern struct tty_driver *console_device(int

*);

arch/um/drivers/stdio_console.c:207 has struct tty_driver *console_device(struct

console *c, int *index)



so, on a wild 'whim' I changed console_device in stdio_console.c

to uml_console_device.



That compiles, but then it ends with an linker error:



vmlinux(.text+0x2d8b0): In function `alloc_pidmap':

vmlinux(.text+0x4faef): In function `get_unused_fd':

collect2: ld returned 1 exit status

make: *** [linux] Error 1



Probably something simple, but I wanted to discuss with folks

more in the now on if the above (stdio_console) fix was the right

one, and to find out if anyone else has an idea of how to fixe

the find_next_zero_bit error.



Thanks,

George
