Subject: [openrisc] uclinux running error problem
Hi
I use the cygwin gcc:gcc version 3.1 20020121 (experimental).
This problem does not occur in or1ksim.It runs correctly in or1ksim!
I found in the file /mmnommu/Page_alloc.c:
#define RMQUEUE(order, dma) \
do { struct free_area_struct * area = free_area+order; \
unsigned long new_order = order; \
do { struct page *prev = memory_head(area), *ret; \
while (memory_head(area) != (ret = prev->next)) { \
if (!dma || CAN_DMA(ret)) { \
unsigned long map_nr = ret-
>map_nr; \
(prev->next = ret->next)->prev =
prev; \
MARK_USED(map_nr, new_order,
area); \
nr_free_pages -= 1 << order; \
EXPAND(ret, map_nr, order,
new_order, area); \
restore_flags(flags); \
return ADDRESS(map_nr); \
} \
prev = ret; \
} \
new_order++; area++; \
} while (new_order < NR_MEM_LISTS); \
} while (0)

I use printk function and find "map_nr" is always zero but in or1ksim it is
not zero!What's wrong with me?

Regards
