Attempt to fix the problem wherein people's oops reports scroll off the screen
due to repeated oopsing or to oopses on other CPUs.
If this happens the user can reboot with the `pause_on_oops=<seconds>' option.
It will allow the first oopsing CPU to print an oops record just a single
time. Second oopsing attempts, or oopses on other CPUs will cause those CPUs
to enter a tight loop until the specified number of seconds have elapsed.
The patch implements the infrastructure generically in the expectation that
architectures other than x86 will find it useful.

This patch introduces a user space interface for swsusp.
The interface is based on a special character device, called the snapshot
device, that allows user space processes to perform suspend and resume-related
operations with the help of some ioctls and the read()/write() functions.
Additionally it allows these processes to allocate free swap pages from a
selected swap partition, called the resume partition, so that they know which
sectors of the resume partition are available to them.
The interface uses the same low-level system memory snapshot-handling
functions that are used by the built-it swap-writing/reading code of swsusp.
The interface documentation is included in the patch.
The patch assumes that the major and minor numbers of the snapshot device will
be 10 (ie. misc device) and 231, the registration of which has already been
requested.

Update suspend-to-RAM documentation with new machines, and makes message

Warn in the documentation that data may be lost if there are some

Signed-off-by: Linus Torvalds <torvalds@osdl.org>
The device, Medion 7134, has two saa7134 chips on it, but only one of them
is functional in the current saa7134 driver.
This patch adds autodetection for the second, unsupported saa7134 chip,
as SAA7134_BOARD_MD7134_BRIDGE_2, and displays a message to the user
(in dmesg) indicating that the second chip isn't yet functional.
This is useful for users, since two instances of the saa7134 driver
will spawn. This patch will prevent confusion by warning the user that
only one of the chips on the board are functional.
There are other versions of the SAA7134_BOARD_MD7134 with only a single
saa7134 bridge/decoder -- those devices will not be affected by this patch.
Only devices containing the second chip will display the warning.

Resolved as in the original merge by Mauro Carvalho Chehab
Back in the dark ages, we had to be conservative and only allow 15-bit
window fields if the window scale option was not negotiated. Some
ancient stacks used a signed 16-bit quantity for the window field of
the TCP header and would get confused.
Those days are long gone, so we can use the full 16-bits by default
now.
There is a sysctl added so that we can still interact with such old
stacks
