Is the new generic KGDB patch in upstream-akpm?

Is the new generic KGDB patch in upstream-akpm?

[Daniel Laird]

I am trying to respin the patch to add pnx833x support to linux 2.6.27.
I wanted to patch against the new generic kernel KGDB patch.
So I removed gdb-hook etc.

However when I compile I get
arch/mips/kernel/built-in.o: In function `early_console_write':
early_printk.c:(.init.text+0x1450): undefined reference to `prom_putchar'
early_printk.c:(.init.text+0x1450): relocation truncated to fit:
R_MIPS_26 against `prom_putchar'
early_printk.c:(.init.text+0x145c): undefined reference to `prom_putchar'
early_printk.c:(.init.text+0x145c): relocation truncated to fit:
R_MIPS_26 against `prom_putchar'
make[1]: *** [.tmp_vmlinux1] Error 1

These functions were defined in my gdb-hook.c.  Do I need to move
these somewhere else now? Or just not support EARLY_PRINTK etc.

Is this true?
Cheers

Bad choice - early printk has no relation whatsoever to GDB - though both
might end bitbanging the same serial, so early printk code should live
in a different file.
