Re: Bug#263348: linux-kernel-headers: asm/unaligned.h on powerpc is useless if __KERNEL__ is undefined

[Domenico Andreoli <cavok@debian.org>]

hi again,

i have attached a workaround for bug #263348 in case nobody wants to
fix it linux-kernel-headers.

it should work although being not that elegant. i know it is fragile
since relies on _PPC_ERRNO_H macro being defined by asm/errno.h on
powerpc and that could change in any moment.

anybody has a better suggestion to guess the architecture?

cheers
domenico
