[PATCH] fix s390[x] to print the correct freed memory amount

[PATCH] fix s390[x] to print the correct freed memory amount

[Dan Aloni]

This is purely because arch/s390/mm/init.c does:

	extern unsigned long _text;
	extern unsigned long _etext;
	extern unsigned long _edata;
	extern unsigned long __bss_start;
	extern unsigned long _end;

	extern unsigned long __init_begin;
	extern unsigned long __init_end;

And as you know C, here (&__init_end - &__init_begin) >> 10) will 
not evaluate to the right value because of 'unsigned long'.

Linus, this is a good reason why I introduced asm-generic/sections.h
and asm-i386/sections.h. I think there should be a sections.h file 
every arch, in order to avoid having every .c file declare its own 
idea of what those symbols are.

BTW, I have another patch which adds a sections.h for every arch
and removes the cruft of the extern declarations, while adding 
an #include <asm/sections.h>.

ChangeSet@1.544, 2002-07-30 22:58:38+03:00, da-x@gmx.net
  Make s390 and s390x print the right freed init memory size.
  The expression (&__init_begin - &__init_end) depends on the type
  of this adhoc extern variables, which was changed from char to long
  when the code was copied from another arch.
