Subject2.2.18pre13: Small patches
Here's a brace of small patches that ought to be OK for 2.2.18.
adTHANKSvance for consideration

1. Fix fencepost error in ioremap's page reservation logic.
(I think the broken logic was added to support AGP.)

}

2. Fix linear RAID to work even with blocks smaller than 1K.
(From Anton Altparmakov <antona@bigfoot.com>)

In linux/drivers/block/linear.c:linear_map(), change:
*rsector=(block-(tmp_dev->offset)) << 1;
to:
*rsector=((block - tmp_dev->offset) << 1) + (*rsector & 1);


3. Trivial patch to fs/vfat/namei.c to avoid a compile-time warning.

4. Config option controlling default behavior of kernels that enable
boot-time IP-Config.

* If CONFIG_IP_PNP_AUTO is set, the default is to do IP-Config at
boot time. Disable it with "ip=off".
* If CONFIG_IP_PNP_AUTO is not set, the default is *not* to do
IP-Config at boot time. Override with "ip=on", "ip=dhcp", etc.
