[PATCH] ARM: 2709/1: Systems with PCMCIA should also see IDE options (for CompactFlash memories)

Patch from David Brownell

The ARM generic Kconfig filters out IDE options ... except for
an error prone ARMload of special cases.
This adds one general case to the systems that will offer IDE options:
kernels with PCMCIA support, which probably want to use IDE to access
CompactFlash cards.  This might allow many (most?) of the other cases
to disappear, for systems that only see IDE hardware through CF cards.
Right now this one patch is used to gate access to CF cards, including
MicroDrives, for both omap_cf and at91_cf drivers.

Benjamin Herrenschmidt [Fri, 10 Jun 2005 04:19:02 +0000]
[PATCH] ppc32: Fix nasty sleep/wakeup problem

Despite all the care lately in making the powermac sleep/wakeup as
robust as possible, there is still a nasty related to the use of cpufreq
on PMU based machines.  Unfortunately, it affects paulus old powerbook
so I have to fix it :)

We didn't manage to understand what is precisely going on, it leads to
memory corruption and might have to do with RAM not beeing properly
refreshed when a cpufreq transition is done right before the sleep.

The best workaround (and less intrusive at this point) we could come up
with is included in this patch.  We basically do _not_ force a switch to
high speed on suspend anymore (that is what is causing the problem) on
those machines.  We still force a speed switch on wakeup (since we don't
know what speed we are coming back from sleep at, and that seems to work
fine).

Since, during this short interval, the actual CPU speed might be
incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max
speed factor on those machines) during early wakeup stage to make sure
udelay's during that time aren't too short.

For after 2.6.12, we'll change udelay implementation to use the CPU
timebase (which is always constant) instead like we do on ppc64 and thus
get rid of all those problems.

Michael Ellerman [Thu, 9 Jun 2005 19:36:33 +0000]
[PATCH] iseries_veth: Supress spurious WARN_ON() at module unload

My patch from a few weeks back (now in mainline), called "Cleanup skbs to
prevent unregister_netdevice() hanging", can cause our TX timeout code to
fire on machines with lots of VLANs (because it takes > 2 seconds between
when we stop the queues and when we're finished stopping the connections).

When that happens the TX timeout code freaks out and does a WARN_ON()
because as far as it's concerned there shouldn't be a TX timeout happening,
which is fair enough.

I have a "proper" fix for this, which is to a) do refcounting on
connections and b) implement a proper ack timer so we don't keep unacked
skbs lying around for ever.  But for 2.6.12 I propose just supressing the
WARN_ON().  Users will still see the "NETDEV WATCHDOG" warning, but that's
not nearly as bad as a WARN_ON() which users interpret as an Oops.

Ian Abbott [Thu, 2 Jun 2005 09:34:11 +0000]
[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc

ftdi_sio: Avoid losing bytes at tty-ldisc.

This patch was originally developed by Daniel Smertnig.  I
(Ian Abbott) made a few changes.  It has been tested by both
Daniel and I, at least for raw, non-canonical receive data
processing.

Here is Daniel's original description of the patch:

===
During a project in which I was using a FTDI 232BM to
transmit data at relative high speeds (625kBit/s), I
noticed a problem where data was lost even if flow
control was enabled: The FTDI-Driver receives 512 Bytes
of data over USB at a time, which consists of 8 64-Byte
packets. Subtracting the 2 bytes of status information
included in each packet this gives 496 "real" data
bytes per read.

This data is passed (indirectly, via the flip buffers)
to the tty line discipline which takes care of
throttling when there the free buffer space reaches
TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver
processes up to 496 bytes at a time, throttling won't
happen in time and the line discipline will discard the
remaining bytes.

To avoid this the patch passes data in 62-byte blocks
to the tty layer and checks the available space in the
ldisc-buffers. If there isn't enough free space,
processing the rest of the data is delayed using a
workqueue.

Note: The original problem should be easily
reproducible with a userspace program which does slow &
small reads.

[PATCH] ia64: fix floating-point preemption problem

There've been reports of problems with CONFIG_PREEMPT=y and the high
floating point partition.  This is caused by the possibility of preemption
and rescheduling on a different processor while saving or restioirng the
high partition.

The only places where the FPU state is touched are in ptrace, in
switch_to(), and where handling a floating-point exception.  In switch_to()
preemption is off.  So it's only in trap.c and ptrace.c that we need to
prevent preemption.

Here is a patch that adds commentary to make the conditions clear, and adds
appropriate preempt_{en,dis}able() calls to make it so.  In trap.c I use
preempt_enable_no_resched(), as we're about to return to user space where
the preemption flag will be checked anyway.

[PATCH] uml: fix strace -f

It turns out that we need to check for pending signals when a newly forked
process is run for the first time.  With strace -f, strace needs to know about
the forked process before it gets going.  If it doesn't, then it ptraces some
bogus values into its registers, and the process segfaults.  So, I added calls
to interrupt_end, which does that, plus checks for reschedules.  There
shouldn't be any of those, but x86 does the same thing, so I'm copying that
behavior to be safe.

David Mosberger [Mon, 4 Apr 2005 20:29:43 +0000]
[PATCH] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).

[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).

As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices.  This isn't always true.  Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.

The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode.  I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place.  According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.

With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).

Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.

This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.

[PATCH] AGP fix for Xen VMM

When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART.  This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.

Architecture-specific functions are also defined for allocating and freeing
the GATT.  Xen requires this to ensure that table really is contiguous from
the point of view of the GART.

These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.

[PATCH] Include <linux/config.h> before testing CONFIG_ACPI

I'm not sure why this issue is suddenly showing, but without this
patchlet, the zx1 config won't compile anymore (e.g., to see the
compilation-error, look for "***" in [1]).

[TG3] Fix link failure in 5701

On some 5701 devices with older bootcode, the LED configuration bits in
SRAM may be invalid with value zero. The fix is to check for invalid
bits (0) and default to PHY 1 mode. Incorrect LED mode will lead to
error in programming the PHY.

Thanks to Grant Grundler for debugging the problem.

>From Grant:
| In May, 2004,  tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting
| programmed and how to determine what to program into LED_CTRL. The new
| code trusted NIC_SRAM_DATA_CFG (0x00000b58) to indicate what to write
| to LED_CTRL and MII EXT_CTRL registers. On "IOX Core Lan", SRAM was
| saying MODE_MAC (0x0) and that doesn't work.

matters only in (currently impossible) case of symlink mounted on something,
but it's trivial to fix and that actually makes more sense.

[PATCH] namei fixes (15/19)

Getting rid of sloppy logics:

a) in do_follow_link() we have the wrong vfsmount dropped if our symlink
had been mounted on something.  Currently it worls only because we never
get such situation (modulo filesystem playing dirty tricks on us).  And
it obfuscates already convoluted logics...

b) same goes for open_namei().

c) in __link_path_walk() we have another "it should never happen" sloppiness -
out_dput: there does double-free on underlying vfsmount and leaks the covering
one if we hit it just after crossing a mountpoint.  Again, wrong vfsmount
getting dropped.

d) another too-early-mntput() race - in do_follow_mount() we need to postpone
conditional mntput(path->mnt) until after dput(path->dentry).  Again, this one
happens only in it-currently-never-happens-unless-some-fs-plays-dirty
scenario...

[PATCH] namei fixes (13/19)

In open_namei() exit_dput: we have mntput() done in the wrong order -
if nd->mnt != path.mnt we end up doing
mntput(nd->mnt);
nd->mnt = path.mnt;
dput(nd->dentry);
mntput(nd->mnt);
which drops nd->dentry too late.  Fixed by having path.mnt go first.
That allows to switch O_NOFOLLOW under if (__follow_mount(...)) back
to exit_dput, while we are at it.

Fix for early-mntput() race + equivalent transformation.

Then we shift the result downstream.
