Summary: iSCSI fails when sg->page in high memory

Initial Comment:
In fuction :
iscsi_buf_init_sg(struct iscsi_buf *ibuf, struct 
scatterlist *sg)

of iscsi_tcp.c

page_address(sg->page) returns zero when sg->page is 
in high memory.

The result is that the whole iSCSI layer will fail.

Kernel version:
linux kernel 2.6.11-1.1369_FC4 SMP and  2.6.14.4 #7 
SMP


All this happen when the system is under heavy load 
writing huge amount of date ove the iSCSI connection 
(56 Mbyte/sec)
