For recent ISPs, software must detect OVERRUN conditions by
checking the SS_RESIDUAL_OVER bit during CS_COMPLETE handling.
Update the driver to perform this check, which is consistent with
what earlier firmwares did by explicitly cracking open the
FCP_RSP statuses and returning an CS_DATA_OVERRUN.

There's no point in hitting the RISC with what will most
assuredly be an unsucessful reset of the RISC hardware if the
initial stop-firmware mailbox command fails with a time-out

driver unloading and discard the stop-firmware requirement.

- get_host_speed (speed)
- get_host_port_state (port_state)
- get_host_port_type (port_type)

FCE support enables the firmware to record FC extended link
services and basic link services frames which have been
transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be

Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.
For more info regarding lifetime rule cleanup, please read the

(tweaked by Greg to not delete the field just yet, to make it easier to
merge things properly.)

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
Compile tested with make all{yes,mod}config on x86_64 and i386.

* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
[SPARC64]: Optimize fault kprobe handling just like powerpc.
[SPARC]: Wire up utimensat syscall.
[SPARC64]: Fix request_irq() ignored result warnings in PCI controller code.
[SPARC64]: Kill asm-sparc64/pbm.h
[ATYFB]: Fix sparc includes.
[QLA2XXX]: Fix build on sparc.
[SPARC64]: Removal of trivial pci_controller_info uses.
[SPARC64]: Move index info pci_pbm_info.
[SPARC64]: Move {setup,teardown}_msi_irq into pci_pbm_info.
[SPARC64]: Move pci_ops into pci_pbm_info.
[SPARC64] SBUS: Error interrupt registry cleanups.
[SPARC64] PCI: Use root list of pbm's instead of pci_controller_info's
[SPARC64] PCI: Kill PROM_PCIRNG_MAX and PROM_PCIIMAP_MAX.
[SPARC64] PCI: Use common routine to fetch PBM properties.
We now use pci_device_to_OF_node() to get properties
and of_get_property() returns const pointers.
