52cb1c2b70 Fix error checking in Vitesse IRQ config
phy_read() returns a negative number if there's an error, but the
error-checking code in the Vitesse driver's config_intr function
triggers if phy_read() returns non-zero.  Correct that.

1d5e83aac5 Fix Vitesse 824x PHY interrupt acking
The Vitesse 824x PHY doesn't allow an interrupt to be cleared if
the mask bit for that interrupt isn't set.  This means that the PHY
Lib's order of handling interrupts (disable, then clear) breaks on this
PHY.  However, clearing then disabling the interrupt opens up the code
for a silly race condition.  So rather than change the PHY Lib, we change
the Vitesse driver so it always clears interrupts before disabling them.
Further, the ack function only clears the interrupt if interrupts are
enabled.

28e53bddf8 unify flush_work/flush_work_keventd and rename it to cancel_work_sync
flush_work(wq, work) doesn't need the first parameter, we can use cwq->wq
(this was possible from the very beginnig, I missed this).  So we can unify
flush_work_keventd and flush_work.

Also, rename flush_work() to cancel_work_sync() and fix all callers.
Perhaps this is not the best name, but "flush_work" is really bad.

024a0a3cfb network: add the missing phy_device speed information to phy_mii_ioctl
Function `phy_mii_ioctl' returns physical device's information based on
user requests.  When requested to return the basic mode control register
information (BMCR), the original implementation only returns the physical
device's duplex information and forgets to return speed information, which
should not be because BMCR register is used to hold both duplex and speed
information.

The patch checks the BMCR value against speed-related flags and fills the
return structure's speed field accordingly.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

68380b5813 Add "run_scheduled_work()" workqueue function
This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running.  This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.

It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.

Also, this is strictly only usable for work that has been scheduled
without any delayed timers.  You can not mix the new interface with
schedule_delayed_work().

But it's better than what we had currently.

Most PHYs connect to an ethernet controller over a GMII or MII
interface.  However, a growing number are connected over
different interfaces, such as RGMII or SGMII.

The ethernet driver will tell the PHY what type of connection it
is by setting it manually, or passing it in through phy_connect
(or phy_attach).

Changes include:
* Updates to documentation
* Updates to PHY Lib consumers
* Changes to PHY Lib to add interface support
* Some minor changes to whitespace in phy.h
* gianfar driver now detects interface and passes appropriate

3c3070d713 [PATCH] 2.6.18: sb1250-mac: Phylib IRQ handling fixes
This patch fixes a couple of problems discovered with interrupt handling
in the phylib core, namely:

1. The driver uses timer and workqueue calls, but does not include
   <linux/timer.h> nor <linux/workqueue.h>.

2. The driver uses schedule_work() for handling interrupts, but does not
   make sure any pending work scheduled thus has been completed before
   driver's structures get freed from memory.  This is especially
   important as interrupts may keep arriving if the line is shared with
   another PHY.

   The solution is to ignore phy_interrupt() calls if the reported device
   has already been halted and calling flush_scheduled_work() from
   phy_stop_interrupts() (but guarded with current_is_keventd() in case
   the function has been called through keventd from the MAC device's
   close call to avoid a deadlock on the netlink lock).

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

84c22d7901 [PATCH] Signedness issue in drivers/net/phy/phy_device.c
While checking gcc 4.1 -Wextra warnings, I stumbled across the following
two warnings:

drivers/net/phy/phy_device.c:528: warning: comparison of unsigned expression < 0 is always false
drivers/net/phy/phy_device.c:546: warning: comparison of unsigned expression < 0 is always false

Since phy_read() returns an integer and can return negative values, it seems
to me the best way to get proper error handling working again is to make val
an int.  Currently it is an u32, so the < 0 check always fails.

11b0bacd71 [PATCH] PAL: Support of the fixed PHY
This makes it possible for HW PHY-less boards to utilize PAL goodies.  Generic
routines to connect to fixed PHY are provided, as well as ability to specify
software callback that fills up link, speed, etc.  information into PHY
descriptor (the latter feature not tested so far).

817acf5ebd [PATCH] Stop calling phy_stop_interrupts() twice
Prevent phylib from freeing PHY IRQ twice on closing an eth device:
phy_disconnect() first calls phy_stop_interrupts(), then it calls
phy_stop_machine() which in turn calls phy_stop_interrupts() making the
kernel complain on each bootup...
