Mikael Pettersson <mikpe@csd.uu.se> noted that the current 2.6-git (and 2.4)
patch to disallow KDSKBSENT for unpriviledged users should be less restrictive
allowing reading of current function key string entry, but not writing.

This patch has the changes to support the memory floor fix done in Dell
BIOS. The BIOS incase of packet update mechanism would not accept packet
placed in memory below a cretain address. This address is by default 128K
but can change. The driver now can accept the memory floor if the user
chooses to make it will try to allocate contiguous physical memory above
the memory floor by allocating a set of packets till a valid memory
allocation is made. All the allocates then are freed. This repeats for
everty packet.
This patch was created by Michael E Brown and has been tested on 2.6.14-rc5

driver_unregister is not being properly called when the init function
returns an error case. Restructured the return logic such that this and
the other cleanups all happen in one place. Preformed many of the cleanups
that Andrew Morton's patch on Thursday made in tpm_atmel.c. Fixed
Matthieu's concern about writing before discovery.
(akpm: rmk said:
This driver is buggy. You must not provide your own release function - it
doesn't solve the problem which the warning (which you get when you don't
provide one) is telling you about.
You should convert your device driver over to the replacement dynamic platform
support, once it is merged. IOW, something like:
pdev = platform_device_alloc("mydev", id);
if (pdev) {
err = platform_device_add_resources(pdev, &resources,
ARRAY_SIZE(resources));
if (err == 0)
err = platform_device_add_data(pdev, &platform_data,
sizeof(platform_data));
if (err == 0)
err = platform_device_add(pdev);
} else {
err = -ENOMEM;
}
if (err)
platform_device_put(pdev);
)

There is a wrong BUG in mxser_close.
The BUG is triggered when tty->driver_data == NULL, But in fact this is not
a bug, because tty->driver->close is called even when tty->driver->open
fails.
LDD3 tells us to do nothing in such cases.

This patch adds a connector that reports fork, exec, id change, and exit
events for all processes to userspace. It replaces the fork_advisor patch
that ELSA is currently using. Applications that may find these events
useful include accounting/auditing (e.g. ELSA), system activity monitoring
(e.g. top), security, and resource management (e.g. CKRM).

Access to FBA disks via DIAG fails for block sizes > 512 byte. The device
analysis code of the DIAG discipline does not properly initialize the DIAG250
device environment after completion of the analysis. This results in VM only
serving 512 bytes per block I/O request whereas Linux expects larger block
sizes. Add proper device environment setup to end of analysis code.

This extends the API somewhat to allow for platform-specific VCR reading and
writing. Some platforms (like SH4-202) implement the VCR in a split VCRL and
VCRH, but end up being in reverse order or have other quirks that need to be
dealt with, so we add a set of superhyway_ops per-bus to accomodate this.
We also have to extend the per-device resources somewhat, as some devices now
conveniently split control and data blocks. So we allow a platform to
register its set of SuperHyway devices via superhyway_add_devices() with the
control block always ordered as the first resource (as this is the one that
userspace cares about).

Add capability for 3c59x driver to use memory-mapped PCI I/O resources.
This may improve performance for those devices so equipped. This will be
the default behaviour for IS_CYCLONE and IS_TORNADO devices. Additionally,
it can be enabled/disabled individually for up to MAX_UNITS number of
devices via the use_mmio module option or for all units via the
global_use_mmio option. The use_mmio option overrides the global_use_mmio
option for those devices specified.

We've noticed that sometimes "MTD do_write_buffer(): software timeout"
message was printed out when writing to a Fujitsu NOR flash.
It turned out that this was because of a race in the timeout handling
do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and
sometimes if the timer interrupt handling takes more than one or even two
jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just
after chip_ready() call, the driver bails out from a ready polling loop
despite the chip has actually become ready while all those interrupts were
handled. To deal with this issue, extra check for chip ready is neccessary on
timeout expiration (and the checks should better be reordered).
As do_write_oneword() uses the same approach, it needs to also be changed.
