Fix more include file problems that surfaced since I submitted the previous
fix-missing-includes.patch. This should now allow not to include sched.h
from module.h, which is done by a followup patch.Signed-off-by: Tim Schmielau

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).Signed-off-by: Matt Helsley

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.Signed-off-by: Peter Oberparleiter

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).Signed-off-by: Paul Mundt

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.Signed-off-by: John W. Linville

Some visually impaired people use hardware devices which directly read
the vga screen. When newt for instance asks to hide the cursor for
better visual aspect, the kernel puts the vga cursor out of the screen,
so that the cursor position can't be read by the hardware device. This
is a great loss for such people.Here is a patch which uses the same technique as CUR_NONE for hiding the
cursor while still moving it.Mario, you should apply it to the speakup kernel for access floppies
asap. I'll submit a 2.4 patch too.Signed-off-by: samuel.thibault@ens-lyon.org

Statically allocated devices in module data is a potential cause
of oopsen. The device may be in use by a userspace process, which
will keep a reference to the device. If the module is unloaded,
the module data will be freed. Subsequent use of the platform
device will cause a kernel oops.Use generic platform device allocation/release code in modules.

Adds a phy_mask field to struct mii_bus and uses it. This field
indicates each phy address to be ignored when probing the mdio bus.This support is needed for the fs_enet and ibm_emac drivers to be
converted to the generic phy layer among other drivers. Many systems
lock up on probing certain phy addresses or probing doesn't return
0xffff when nothing is found at the address. A new driver I'm
working on also makes use of this mask.Signed-off-by: Matt Porter

This patch is a better fix for Allied Telesyn 2700/2701 FX boards than
the change made in early January this year. It allows the user to
select the speed/duplex via module_param, but if no selection is made,
forces the speed to 100 FD. It fixes both Bugzilla bugs 2669 and 4551.
