Mirror the logic in the sun4u handler, we have to update
both registers even when we branch out to window fault
fixup handling.

The way it works is that if we are in etrap processing a
fault already, g4/g5 holds the original fault information.
If we take a window spill fault while doing etrap, then
we put the window spill fault info into g4/g5 and this is
what the top-level fault handler ends up processing first.

Then we retry the originally faulting instruction, and
process the original fault at that time.

This is all necessary because of how constrained the trap
registers are in these code paths.  These cases trigger
very rarely, so even if there is some performance implication
it's doesn't happen very often.  In fact the rarity is why

"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on

that the first pointer is 'struct readdir_cd *' rather than 'void *'.  It

other type mismatches between the two such as the fact that the 'ino' arg
recently changed from ino_t to u64.

So: get rid of 'encode_dent_fn', get rid of the cast of the function type,
change the first arg of various functions from 'struct readdir_cd *' to
'void *', and live with the fact that we have a little less type checking
on the calling of these functions now.  Less internal (to nfsd) checking

[PATCH] dm-multipath: fix stall on noflush suspend/resume

Allow noflush suspend/resume of device-mapper device only for the case
where the device size is unchanged.

Otherwise, dm-multipath devices can stall when resumed if noflush was used
when suspending them, all paths have failed and queue_if_no_path is set.

Explanation:
 1. Something is doing fsync() on the block dev,
    holding inode->i_sem
 2. The fsync write is blocked by all-paths-down and queue_if_no_path
 3. Someone requests to suspend the dm device with noflush.
    Pending writes are left in queue.
 4. In the middle of dm_resume(), __bind() tries to get
    inode->i_sem to do __set_size() and waits forever.

'noflush suspend' is a new device-mapper feature introduced in
early 2.6.20. So I hope the fix being included before 2.6.20 is
released.

Example of reproducer:
 1. Create a multipath device by dmsetup
 2. Fail all paths during mkfs
 3. Do dmsetup suspend --noflush and load new map with healthy paths
 4. Do dmsetup resume

[PATCH] knfsd: Don't mess with the 'mode' when storing a exclusive-create cookie

NFS V3 (and V4) support exclusive create by passing a 'cookie' which can get
stored with the file.  If the file exists but has exactly the right cookie
stored, then we assume this is a retransmit and the exclusive create was
successful.

The cookie is 64bits and is traditionally stored in the mtime and atime
fields.  This causes a problem with Solaris7 as negative mtime or atime
confuse it.  So we moved two bits into the mode word instead.

But inherited ACLs sometimes overwrite the mode word on create, so this is a
problem.

So we give up and just store 62 of the 64 bits and assume that is close
enough.

[PATCH] ACPI: fix cpufreq regression

Recently cpufreq support on my laptop (Lenovo T60) broke completely: when
it's plugged into AC it would never go higher than 1 GHz - neither 1.3 GHz
nor 1.83 GHz is possible - no matter which governor (userspace, speed or
ondemand) is used.

After some cpufreq debugging i tracked the regression back to the following
(totally correct) bug-fix commit:

   commit 0916bd3ebb7cefdd0f432e8491abe24f4b5a101e
   Author: Dave Jones <davej@redhat.com>
   Date:   Wed Nov 22 20:42:01 2006 -0500

    [PATCH] Correct bound checking from the value returned from _PPC method.

This bugfix, which makes other laptops work, made a previously hidden
(BIOS) bug visible on my laptop.

The bug is the following: if the _PPC (Performance Present Capabilities)
optional ACPI object is queried /after/ bootup then the BIOS reports an
incorrect value of '2'.

My laptop (Lenovo T60) has the following performance states supported:

   0: 1833000
   1: 1333000
   2: 1000000

Per ACPI specification, a _PPC value of '0' means that all 3 performance
states are usable.  A _PPC value of '1' means states 1 ..  2 are usable, a
value of '2' means only state '2' (slowest) is usable.

now, the _PPC object is optional, and it also comes with notification.
Furthermore, when a CPU object is initialized, the _PPC object is
initialized as well.  So the following evaluation of the _PPC object is
superfluous:

 [<c028ba5f>] acpi_processor_get_platform_limit+0xa1/0xaf
 [<c028c040>] acpi_processor_register_performance+0x3b9/0x3ef
 [<c0111a85>] acpi_cpufreq_cpu_init+0xb7/0x596
 [<c03dab74>] cpufreq_add_dev+0x160/0x4a8
 [<c02bed90>] sysdev_driver_register+0x5a/0xa0
 [<c03d9c4c>] cpufreq_register_driver+0xb4/0x176
 [<c068ac08>] acpi_cpufreq_init+0xe5/0xeb
 [<c010056e>] init+0x14f/0x3dd

And this is the point where my laptop's BIOS returns the incorrect value of
'2'.  Note that it has not sent any notification event, so the value is
probably not really intentional (possibly spurious), and Windows likely
doesnt query it after bootup either.  Maybe the value is kept at '2'
normally, and is only set to the real value when a true asynchronous event
(such as AC plug event, battery switch, etc.) occurs.

So i /think/ this is a grey area of the ACPI spec: per the letter of the
spec the _PPC value only changes when notified, so there's no reason to
query it after the system has booted up.  So in my opinion the best (and
most compatible) strategy would be to do the change below, and to not
evaluate the _PPC object in the acpi_processor_get_performance_info() call,
but only evaluate it if _PPC is present during CPU object init, or if it's
notified during an asynchronous event.  This change is more permissive than
the previous logic, so it definitely shouldnt break any existing system.

This also happens to fix my laptop, which is merrily chugging along at
1.83 GHz now. Yay!

[PATCH] SPI: alternative fix for spi_busnum_to_master

If a SPI master device exists, udev (udevtrigger) causes kernel crash, due
to wrong kobj pointer in kobject_uevent_env().  This problem was not in
2.6.19.

The backtrace (on MIPS) was:
[<8024db6c>] kobject_uevent_env+0x54c/0x5e8
[<802a8264>] store_uevent+0x1c/0x3c  (in drivers/class.c)
[<801cb14c>] subsys_attr_store+0x2c/0x50
[<801cb80c>] flush_write_buffer+0x38/0x5c
[<801cb900>] sysfs_write_file+0xd0/0x190
[<80181444>] vfs_write+0xc4/0x1a0
[<80181cdc>] sys_write+0x54/0xa0
[<8010dae4>] stack_done+0x20/0x3c

flush_write_buffer() passes kobject of spi_master_class.subsys to
subsys_addr_store(), then subsys_addr_store() passes a pointer to a struct
subsystem to store_uevent() which expects a pointer to a struct
class_device.  The problem seems subsys_attr_store() called instead of
class_device_attr_store().

This mismatch was caused by commit
3bd0f6943520e459659d10f3282285e43d3990f1, which overrides kset of master
class.  This made spi_master_class.subsys.kset.ktype NULL so
subsys_sysfs_ops is used instead of class_dev_sysfs_ops.

The commit was to fix spi_busnum_to_master().  Here is a patch fixes
this function in other way, just searching children list of
class_device.

get_gate_vma after real vmas in the same way the /proc/PID/maps code does.

This changes core dumps so they no longer include the non-PT_LOAD phdrs from

Resurrect 'try_to_free_buffers()' VM hackery

It's not pretty, but it appears that ext3 with data=journal will clean
pages without ever actually telling the VM that they are clean.  This,
in turn, will result in the VM (and balance_dirty_pages() in particular)
to never realize that the pages got cleaned, and wait forever for an
event that already happened.

Technically, this seems to be a problem with ext3 itself, but it used to
be hidden by 'try_to_free_buffers()' noticing this situation on its own,
and just working around the filesystem problem.

This commit re-instates that hack, in order to avoid a regression for
the 2.6.20 release. This fixes bugzilla 7844:

http://bugzilla.kernel.org/show_bug.cgi?id=7844

code that this removes from cancel_dirty_page(), and I agree, but for
the imminent release we might as well just silence the warning too

[TCP]: Fix sorting of SACK blocks.

The sorting of SACK blocks actually munges them rather than sort,
causing the TCP stack to ignore some SACK information and breaking the
assumption of ordered SACK blocks after sorting.

The sort takes the data from a second buffer which isn't moved causing
subsequent data moves to occur from the wrong location. The fix is to
use a temporary buffer as a normal sort does.

    [NET]: Fix sk->sk_filter field access

sk_run_filter() returns either 0 or an unsigned 32-bit
length which says how much of the packet to retain.
If that 32-bit unsigned integer is larger than the packet,
this is fine we just leave the packet unchanged.

The above commit caused all filter return values which
were negative when interpreted as a signed integer to
indicate a packet drop, which is wrong.

[IPV4]: Fix the fib trie iterator to work with a single entry routing tables

In a kernel with trie routing enabled I had a simple routing setup
with only a single route to the outside world and no default
route. "ip route table list main" showed my the route just fine but
/proc/net/route was an empty file.  What was going on?

Thinking it was a bug in something I did and I looked deeper.  Eventually
I setup a second route and everything looked correct, huh?  Finally I
realized that the it was just the iterator pair in fib_trie_get_first,
fib_trie_get_next just could not handle a routing table with a single entry.

So to save myself and others further confusion, here is a simple fix for
the fib proc iterator so it works even when there is only a single route
in a routing table.

[MIPS] Fix wrong checksum calculation on 64-bit MIPS

The commit 8e3d8433d8c22ca6c42cba4a67d300c39aae7822 ([NET]: MIPS
checksum annotations and cleanups) broke 64-bit MIPS.

The problem is the commit replaces some unsigned long with __be32.  On
64bit MIPS, a __be32 (i.e. unsigned int) value is represented as a
sign-extented 32-bit value in a 64-bit argument register.  So the
address 192.168.0.1 (0xc0a80001) is passed as 0xffffffffc0a80001 to
csum_tcpudp_nofold() but the asm code in the function expects
0x00000000c0a80001, therefore it returns a wrong checksum.  Explicit
cast to unsigned long is needed to drop high 32bit.
