Geia sou lista!

Exw to akoloy8o ekneyristiko problhma sto Linux 2.2.20pre2 (yparxei kai
sto 2.2.22 opws mporw na dw). Symbainei otan prospa8w na kanw compile
ena opoiodhpote module poy katalhgei na kanei include to <asm/page.h>
(to opoio einai link pros to /usr/src/linux/include/asm-sparc64/page.h).

O 64-bit gcc poy xrhsimopoiw (egcs-2.92.11) stamataei me to akoloy8o mhnyma:

In file included from /usr/include/linux/sched.h:18,
                 from /usr/include/linux/mm.h:4,
                 from /usr/include/linux/slab.h:14,
                 from /usr/include/linux/malloc.h:4,
                 from /usr/include/linux/proc_fs:5,
                 from procfs.c:9:
/usr/include/asm/page.h:96: global register variable follows a function definition
/usr/include/asm/page.h:96: warning: call-clobbered register used for global register variable

Sthn kai gyrw apo thn grammh 96, to <asm/page.h> periexei:

#ifndef __ASSEMBLY__
/* Do prdele, look what happens to be in %g4... */
register unsigned long page_offset asm("g4"); /* This is line no. 96. */
#define PAGE_OFFSET             page_offset
#else
#define PAGE_OFFSET             0xFFFFF80000000000
#endif

H entolh gia th metafrash einai:
egcs64 -D__KERNEL__ -DMODULE -D__SMP__ -O -c -o module.o module.c

(to -D__SMP__ diabasa pws einai apaitoymeno gia pyrhnes me SMP support, akomh ki
an to mhxanhma exei ena epe3ergasth).

Lambanw epishs kai to akoloy8o mhnyma, to opoiow nomizw pws einai asxeto (alla
pote den 3ereis me toys kernels):

O akribws idios kwdikas se Linux 2.2.12-20 me egcs 2.91.66 metafrazetai kai doyleyei
xwris problhma. De symperilambanw ton kwdika epeidh den exei shmasia: arkei na ginetai
include to <asm/page.h>, kai to problhma emfanizetai.

Opoiadhpote boh8eia 8a ektimh8ei :-) .
