Using find_get_page() is a lot faster than find_or_create_page(). This

[PATCH] x86_64: Plug GS leak in arch_prctl()

In linux-2.6.16, we have noticed a problem where the gs base value
returned from an arch_prtcl(ARCH_GET_GS, ...) call will be incorrect if:

   - the current/calling task has NOT set its own gs base yet to a
     non-zero value,

   - some other task that ran on the same processor previously set their
     own gs base to a non-zero value.

In this situation, the ARCH_GET_GS code will read and return the
MSR_KERNEL_GS_BASE msr register.

However, since the __switch_to() code does NOT load/zero the
MSR_KERNEL_GS_BASE register when the task that is switched IN has a zero
next->gs value, the caller of arch_prctl(ARCH_GET_GS, ...) will get back
the value of some previous tasks's gs base value instead of 0.

    Change the arch_prctl() ARCH_GET_GS code to only read and return
    the MSR_KERNEL_GS_BASE msr register if the 'gs' register of the calling
    task is non-zero.

    Side note: Since in addition to using arch_prctl(ARCH_SET_GS, ...),
    a task can also setup a gs base value by using modify_ldt() and write
    an index value into 'gs' from user space, the patch below reads
    'gs' instead of using thread.gs, since in the modify_ldt() case,
    the thread.gs value will be 0, and incorrect value would be returned
    (the task->thread.gs value).

    When the user has not set its own gs base value and the 'gs'
    register is zero, then the MSR_KERNEL_GS_BASE register will not be
    read and a value of zero will be returned by reading and returning
    'task->thread.gs'.

    The first patch shown below is an attempt at implementing this
    approach.

[PATCH] i386/x86-64: Check that MCFG points to an e820 reserved area

This patch introduces a user for the e820_all_mapped function:

There have been several machines that don't have a working MMCONFIG,
often because of a buggy MCFG table in the ACPI bios.  This patch adds a
simple sanity check that detects a whole bunch of these cases, and when
it detects it, linux now boots rather than crash-and-burns.

The accuracy of this detection can in principle be improved if there was
a "is this entire range in e820 with THIS attribute", but no such
function exist and the complexity needed for this is not really worth
it; this simple check already catches most cases anyway.

[PATCH] x86_64: Handle empty PXMs that only contain hotplug memory

The node setup code would try to allocate the node metadata in the node
itself, but that fails if there is no memory in there.

This can happen with memory hotplug when the hotplug area defines an so
far empty node.

Now use bootmem to try to allocate the mem_map in other nodes.

And if it fails don't panic, but just ignore the node.

To make this work I added a new __alloc_bootmem_nopanic function that
does what its name implies.

TBD should try to use nearby nodes here.  Currently we just use any.
It's hard to do it better because bootmem doesn't have proper fallback
lists yet.

[PATCH] x86_64: Reserve SRAT hotadd memory on x86-64

From: Keith Mannthey, Andi Kleen

Implement memory hotadd without sparsemem. The memory in the SRAT
hotadd area is just preserved instead and can be activated later.

There are a few restrictions:
- Only one continuous hotadd area allowed per node

The main problem is dealing with the many buggy SRAT tables
that are out there. The strategy here is to reject anything
suspicious.

Originally from Keith Mannthey, with several hacks and changes by AK
and also contributions from Andrew Morton

[ TBD: Problems pointed out by KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>:

 1) Goto's rebuild_zonelist patch will not work if CONFIG_MEMORY_HOTPLUG=n.

    Rebuilding zonelist is necessary when the system has just memory <
    4G at boot, and hot add memory > 4G.  because x86_64 has DMA32,
    ZONE_NORAML is not included into zonelist at boot time if system
    doesn't have memory >4G at boot.

    [AK: should just force the higher zones at boot time when SRAT tells us]

 2) zone and node's spanned_pages and present_pages are not incremented.
    They should be.

    For example, our server (ia64/Fujitsu PrimeQuest) can equip memory
    from 4G to 1T(maybe 2T in future), and SRAT will *always* say we have
    possible 1T +memory.  (Microsoft requires "write all possible memory
    in SRAT") When we reserve memmap for possible 1T memory, Linux will
    not work well in +minimum 4G configuraion ;)

    [AK: needs limiting to 5-10% of max memory]

[PATCH] splice: page stealing needs to wait_on_page_writeback()

Thanks to Andrew for the good explanation of why this is so. akpm writes:

If a page is under writeback and we remove it from pagecache, it's still
going to get written to disk.  But the VFS no longer knows about that page,
nor that this page is about to modify disk blocks.

So there might be scenarios in which those
blocks-which-are-about-to-be-written-to get reused for something else.
When writeback completes, it'll scribble on those blocks.

This won't happen in ext2/ext3-style filesystems in normal mode because the
page has buffers and try_to_release_page() will fail.

But ext2 in nobh mode doesn't attach buffers at all - it just sticks the
page in a BIO, finds some new blocks, points the BIO at those blocks and
lets it rip.

While that write IO's in flight, someone could truncate the file.  Truncate
won't block on the writeout because the page isn't in pagecache any more.
So truncate will the free the blocks from the file under the page's feet.
Then something else can reallocate those blocks.  Then write data to them.

Now, the original write completes, corrupting the filesystem.

18 years ago[PATCH] sbp2: fix spinlock recursion
Stefan Richter [Sat, 1 Apr 2006 19:11:41 +0000 (21:11 +0200)]
[PATCH] sbp2: fix spinlock recursion

sbp2util_mark_command_completed takes a lock which was already taken by
sbp2scsi_complete_all_commands.  This is a regression in Linux 2.6.15.

 Reported by Kristian Harms at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187394

[ More complete commentary, as response to questions by Andrew: ]

> This changes the call environment for all implementations of
> ->Current_done().  Are they all safe to call under this lock?

Short answer: Yes, trust me.  ;-) Long answer:

The done() callbacks are passed on to sbp2 from the SCSI stack along
with each SCSI command via the queuecommand hook.  The done() callback
is safe to call in atomic context.  So does
Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI
low-level handlers rely on this fact.  So whatever this callback does,
it is "self-contained" and it won't conflict with sbp2's internal ORB
list handling.  In particular, it won't race with the
sbp2_command_orb_lock.

Moreover, sbp2 already calls the done() handler with
sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands().  I
admit this is ultimately no proof of correctness, especially since this
portion of code introduced the spinlock recursion in the first place and
we didn't realize it since this code's submission before 2.6.15 until
now.  (I have learned a lesson from this.)

I stress-tested my patch on x86 uniprocessor with a preemptible SMP
kernel (alas I have no SMP machine yet) and made sure that all code
paths which involve the sbp2_command_orb_lock were gone through multiple
times.

[ARM] 3457/1: i.MX: SD/MMC support for i.MX/MX1

Patch from Pavel Pisa

This patch adds support of i.MX/MX1 SD/MMC controller.
It has been significantly redesigned from the original Sascha Hauer's
version to support scatter-gather DMA, to conform to latest Pierre Ossman's
and Russell King's MMC-SD Linux 2.6.x infrastructure.
The handling of all events has been moved to the softirq context
and is designed with no busy-looping in mind. Unfortunately
some controller bugs has to be overcome by limited looping
about 2-20 usec but these are observed only for initial card
recognition phase.

There are still some missing/missed IRQs problems under heavy load.
Help of somebody with access to the full SDHC design information
is probably necessary.

Regenerated against 2.6.16-git-060402 to solve clash with other patches.
