in one place: where new arrays are created.
Result: if md1 is a raid1, it is stopped and a raid5 is created there, it
might still appear to be a raid1.

Most of the reasons for keeping these separate before was due to hp690
discontig, and since we have a workaround for that now (abusing some shadow
space so everything is magically contiguous), there's no reason to keep the
targets separate.

After ages my fb ioctl prototype cleanup finally got in. Unfortunately the
patch are so old that the sbus compat_ioctl helper didn't exist back then,
so it's not covered. This patch should fix that issue.

There's incorrect spinlock usage in espserial_init(): autoconfig() uses
info->lock before it's initialized. The fix is to initialize the spinlock
earlier.

ESSIDs can technically include NULL characters. Drivers should not be
adjusting the length of the ESSID before reporting it in their
SIOCGIWESSID handlers. Breaks stuff like wpa_supplicant. Note that ipw
drivers, which seem to currently be the "most correct", don't have this
problem.

Host AP driver has code to support writing firmware to non-volatile
memory, a.k.a. flash. This code has been extensively tested when Host
AP was a standalone driver.
Add a configuration option to the kernel to allow enabling this
functionality. Improve the description of the RAM download option.
Mention cards that require it. Remove obsolete scary comment.
