31d40d74b4 [PATCH] FUSE: add access call
Add a new access call, which will only be called if ->permission is invoked
from sys_access().  In all other cases permission checking is delayed until
the actual filesystem operation.

cc4e69dee4 [PATCH] VFS: pass file pointer to filesystem from ftruncate()
This patch extends the iattr structure with a file pointer memeber, and adds
an ATTR_FILE validity flag for this member.

This is set if do_truncate() is invoked from ftruncate() or from
do_coredump().

The change is source and binary compatible.

481bed4542 [PATCH] consolidate sys_ptrace()
The sys_ptrace boilerplate code (everything outside the big switch
statement for the arch-specific requests) is shared by most architectures.
This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
arch_ptrace.

Some architectures have a too different ptrace so we have to exclude them.
They continue to keep their implementations.  For sh64 I had to add a
sh64_ptrace wrapper because it does some initialization on the first call.
For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

796f8d9b98 [PATCH] FUTEX_WAKE_OP: enhanced error handling
The code for FUTEX_WAKE_OP calls an arch callback,
futex_atomic_op_inuser().  That callback can return an error code, but
currently the caller assumes any error is EFAULT, and will try various
things to resolve the fault before eventually giving up with EFAULT
(regardless of the original error code).  This is not a theoretical case -
arch callbacks currently return -ENOSYS if the opcode they are given is
bogus.

This patch alters the code to detect non-EFAULT errors and return them
directly to the user.

Of course, whether -ENOSYS is the correct return value for the bogus opcode
case, or whether EINVAL would be more appropriate is another question.

d55b5fdaf4 [PATCH] aio: remove aio_max_nr accounting race
AIO was adding a new context's max requests to the global total before
testing if that resulting total was over the global limit.  This let
innocent tasks get their new limit tested along with a racing guilty task
that was crossing the limit.  This serializes the _nr accounting with a
spinlock It also switches to using unsigned long for the global totals.
Individual contexts are still limited to an unsigned int's worth of
requests by the syscall interface.

The problem and fix were verified with a simple program that spun creating
and destroying a context while holding on to another long lived context.
Before the patch a task creating a tiny context could get a spurious EAGAIN
if it raced with a task creating a very large context that overran the
limit.

driver_unregister is not being properly called when the init function
returns an error case.  Restructured the return logic such that this and

Matthieu's concern about writing before discovery.

(akpm: rmk said:

This driver is buggy.  You must not provide your own release function - it
doesn't solve the problem which the warning (which you get when you don't
provide one) is telling you about.

You should convert your device driver over to the replacement dynamic platform
support, once it is merged.  IOW, something like:

	pdev = platform_device_alloc("mydev", id);
	if (pdev) {
		err = platform_device_add_resources(pdev, &resources,
						ARRAY_SIZE(resources));
		if (err == 0)
			err = platform_device_add_data(pdev, &platform_data,
						sizeof(platform_data));
		if (err == 0)
			err = platform_device_add(pdev);
		} else {
			err = -ENOMEM;
		}
		if (err)
			platform_device_put(pdev);

1e0291bade [PATCH] s390: dasd diag with block sizes > 512
Access to FBA disks via DIAG fails for block sizes > 512 byte.  The device
analysis code of the DIAG discipline does not properly initialize the DIAG250
device environment after completion of the analysis.  This results in VM only
serving 512 bytes per block I/O request whereas Linux expects larger block
sizes.  Add proper device environment setup to end of analysis code.

86b368a580 [PATCH] s390: dasd diag inline assembly
Future versions of gcc may remove initialization code for control blocks used
by the diag250 inline assembly due to incompletely specified constraints.
This may lead to erratic behavior.  Fix the diag250 inline assembly
constraints.

187dfc67b4 [PATCH] s390: test_bit return value
The test_bit function returns a non-boolean value, it returns 0,1,2,4,...
instead of only 0 or 1.  This causes wrongs results in the mincore system
call.  Check against 0 to get a proper boolean value.

d4b6899678 [PATCH] s390: remove pagex support
Remove pagex pseudo page fault code.  It does not work together with the
system call speedup that makes the complete system call path enabled for
interrupts.  To make pagex and the syscall speedup code work together we would
have to add code to the program check handler to do a critical section cleanup
like the asynchronous interrupt code.  This would make program checks slower.
Not what we want.

Newer versions of z/VM have the improved pfault pseudo page fault interface.
This replaces the old pagex interface and does not have the problem.  So its
better to just rip out the pagex code.

that for ccw devices: Check if the device driver provided a set_{on,off}line
