Hello,
With CONFIG_X86_USE_3DNOW, compilation of init/main.c fails
within '#include <linux/proc_fs.h>. The trigger is use of
in_interrupt() in include/asm-i386/string.h:
__constant_memcpy3d and __memcpy3d. 2.4.0-test1-ac7 gives
the error messages attached.
The obvious fix of also including asm/current.h only
transforms the errors into dereference of an incomplete
type. The definition of task_struct is needed, but including
linux/sched.h is circular and gcc drops it.
I am inclined to place struct task_struct in its own header.
This is core code, and pretty zorkish with macros. Is there
is a less drastic solution to getting per-processor context
in the low level mmx code?
UP + APIC + K7 compiles just fine. Makes me think there must
be another way.
Tom
