795b89d207 [WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()
Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results

The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands.
ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.

62322d2554 [PATCH] make more file_operation structs static
Mark the static struct file_operations in drivers/char as const.  Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..

eed6565f70 [PATCH] Watchdog: Winsystems EPX-C3 SBC
This is a 2.6 patch that adds support for the watchdog timer built into the
EPX-C3 single board computer manufactured by Winsystems, Inc.

Driver details:

This is for x86 only.  This watchdog is pretty basic and simple.  It is
only configurable via jumpers on the SBC, and it only has either a 1.5s or
200s interval.  The watchdog can either be auto-configured to start as soon
as the machine powers up (bad idea for the 1.5s interval!) or it can be
enabled and disabled by writing to io port 0x1ee.  Petting the watchdog
involves writing any value to io port 0x1ef.

The only unfortunate thing about this watchdog (and it is not at all
uncommmon in watchdogs that linux supports) is that it is not a PCI or
ISA-PNP device and as such it isn't at all probeable.  Either the watchdog
exists as 2 bytes at 0x1ee, or it doesn't.  Thus, using this driver on a
machine that doesn't have that watchdog can potentially hang/crash the
system, etc.  So only use this driver if you in fact are on a Winsystems
EPX-C3 SBC.

Anyway this driver fits into the already-existing watchdog framework quite
nicely and I already tested it on my EPX-C3 and it works like a charm.
