Linux Kernel abolished include/linux/config.h long time ago. (around version v2.6.18..v2.6.19) We don't need to provide Linux copatibility any more. This commit deletes include/linux/config.h and fixes source files not to include this. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

/*

* This struct defines the way the registers are stored on the
|
|
* kernel stack during a system call or other kernel entry.
|
|
*
|
|
* this should only contain volatile regs
|
|
* since we can keep non-volatile in the thread_struct
|
|
* should set this up when only volatiles are saved
|
|
* by intr code.
|
|
*
|
|
* Since this is going on the stack, *CARE MUST BE TAKEN* to insure
|
|
* that the overall structure is a multiple of 16 bytes in length.
|
|
*
|
|
* Note that the offsets of the fields in this struct correspond with
|
|
* the PT_* values below. This simplifies arch/powerpc/kernel/ptrace.c.
