empty initcall section

empty initcall section

[Charles Coffing]

I just pulled the latest, and the initialization code for the writable
pagetables (ptwr_init) isn't running at boot time, so Xen crashes.

It appears like there is nothing in the .initcall.init section:
fc551aa0 g       *ABS*  00000000 __initcall_start
fc551aa0 g       *ABS*  00000000 __initcall_end

I would have expected to see ptwr_init listed.

I don't know linker scripts, but perhaps xen.lds is out of date?

Thanks.

Pretty odd. It works for me. :-)

Is __initcall_ptwr_init a symbol within arch/x86/memory.o?

.initcall.init is included in xen.lds, so it should appear in the
final output image.

Perhaps a gcc/binutils issue?

Okay, it's due to a mad renaming of an attribute in recent versions of
GCC. I've checked in a fix.
