This patch creates a file airo.h containing prototypes of the global
functions in airo.c used by airo_cs.c .
If you got strange problems with either airo_cs devices or in any other
completely unrelated part of the kernel shortly or long after a airo_cs
device was detected by the kernel, this might have been caused by the
fact that caller and callee disagreed regarding the size of the first
argument to init_airo_card()...

Refine bnx2_poll() logic to write back the most up-to-date status tag
when all work has been processed. This eliminates some occasional
extra interrupts when a older status tag is written even though all
work has been processed.
The idea is to read the status tag just before exiting bnx2_poll() and
then check again for any new work. If no new work is pending, the
status tag written back will not generate any extra interrupt. This
logic is similar to the changes David Miller did to tg3_poll().

my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID
d5cd4aadd3) introduced a problem with a
program (DOSEMU) that called ioperm after already doing some port i/o.
The problem is that a process switch return causes tss->io_bitmap_base
to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the
io bitmap) never triggers.
This fixes that regression.

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.

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.

Hi,
This patch provides dynamic two buffer-mode and 3 buffer-mode options.
Previously 2 buffer-mode was compilation option. Now with this patch applied
one can load driver in 2 buffer-mode with module-load parameter
ie.
#insmod s2io.ko rx_ring_mode=2
This patch also provides 3 buffer-mode which provides header separation
functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and
"skb_shinfo(skb)->frag_list->data" will have have L4 payload.
one can load driver in 3 buffer-mode with same above module-load parameter

Currently the driver takes a reference only for requests coming by way
of the gendisk, not for requests coming by way of the struct device or
struct scsi_device. Such requests can arrive in the rescan, flush,
and shutdown pathways.
The patch also makes the scsi_disk keep a reference to the underlying
scsi_device, and it erases the scsi_device's pointer to the scsi_disk
when the scsi_device is removed (since the pointer should no longer be
used).
This resolves Bugzilla entry #5237.

Use ata_pad_{alloc,free} in two drivers, to factor out common code.
Add ata_pad_{alloc,free} to two other drivers, which needed the padding
but had not been updated.
This adds support for the Nvidia Geforce 7800 series of cards to the
nvidiafb framebuffer driver. All it does is add the PCI device id for
the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device
table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work
on these cards.
I also added the relevant PCI device ids to linux/pci_ids.h
I tested it on my 7800 GTX here and it works like a charm. I now can
get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text

We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until
we have a merged page.h, define PAGE_SIZE and KERNELBASE locally.
Also gets rid of some dynamic executable cruft that we had for
32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem,
but when we changed to putting . = KERNELBASE in the vmlinux.lds.S
this cruft caused the text to get linked at 0xa0 instead of
0xc0000000. Oops.
