USB: unconfigure devices which have config 0

Some USB devices do have a configuration 0, in contravention of the
USB spec.  Normally 0 is supposed to indicate that a device is
unconfigured.

While we can't change what the device is doing, we can change usbcore.
This patch (as852) allows usb_set_configuration() to accept a config
value of -1 as indicating that the device should be unconfigured.  The
request actually sent to the device will still contain 0 as the value.
But even if the device does have a configuration 0, dev->actconfig
will be set to NULL and dev->state will be set to USB_STATE_ADDRESS.

Without some sort of special-case handling like this, there is no way
to unconfigure these non-compliant devices.

USB: fix g_serial small error

A SET_LINE_CODING control request should return a zero length packet
as an ACK to the host, during the status phase of a USB transaction.

The return value of gs_setup_class() is treated as the number of
bytes to write in the status phase of the control request, by
gs_setup(). For this case, the value returned by gs_setup_class should
be zero for SET_LINE_CODING but, right now, appears to be
sizeof(struct usb_cdc_line_coding).

However, if after doing the memcpy of the line coding descriptor we
set the variable "ret" to be zero, we should return the appropiate ZLP
to the host as an ACK in the status phase of the control request.
I've tested this out using Linux as both host and slave and confirmed
that the following small change fixes the spurious return of
sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase
of a USB_CDC_REQ_SET_LINE_CODING request. It's not a huge bug but, it
is worth fixing.

It is certainly helpful for low-bandwidth devices that can hold their

kobject: kobj->k_name verification fix

The function 'kobject_add' tries to verify the name of
a new kobject instance is properly set before continuing.
    if (!kobj->k_name)
        kobj->k_name = kobj->name;
    if (!kobj->k_name) {
        pr_debug("kobject attempted to be registered with no name!\n");
        WARN_ON(1);
        return -EINVAL;
    }
The statement:
    if (!kobj->k_name) {
        pr_debug("kobject attempted to be registered with no name!\n");
        WARN_ON(1);
        return -EINVAL;
    }
is useless the way it is right now, because it can never be true. I
think the
code was intended to be:
    if (!kobj->k_name)
        kobj->k_name = kobj->name;
    if (!*kobj->k_name) {
        pr_debug("kobject attempted to be registered with no name!\n");
        WARN_ON(1);
        return -EINVAL;
    }
because this would make sure the kobj->name buffer has something in it.
So the missing '*' is just a typo. Although, I would much prefer
expression like:
    if (*kobj->k_name == '\0') {
        pr_debug("kobject attempted to be registered with no name!\n");
        WARN_ON(1);
        return -EINVAL;
    }

because this would've made the intention clear, in this patch I just restore
the missing '*' without changing the coding style of the function.

[PATCH] knfsd: stop NFSD writes from being broken into lots of little writes to filesystem

When NFSD receives a write request, the data is typically in a number of
1448 byte segments and writev is used to collect them together.

Unfortunately, generic_file_buffered_write passes these to the filesystem
one at a time, so an e.g.  32K over-write becomes a series of partial-page
writes to each page, causing the filesystem to have to pre-read those pages
- wasted effort.

generic_file_buffered_write handles one segment of the vector at a time as
it has to pre-fault in each segment to avoid deadlocks.  When writing from
kernel-space (and nfsd does) this is not an issue, so
generic_file_buffered_write does not need to break and iovec from nfsd into
little pieces.

This patch avoids the splitting when  get_fs is KERNEL_DS as it is
from NFSd.

This issue was introduced by commit 6527c2bdf1f833cc18e8f42bd97973d583e4aa83

[PATCH] knfsd: nfsd4: acls: avoid unnecessary denies

We're inserting deny's between some ACEs in order to enforce posix draft acl
semantics which prevent permissions from accumulating across entries in an
acl.

That's fine, but we're doing that by inserting a deny after *every* allow,
which is overkill.  We shouldn't be adding them in places where they actually
make no difference.

Also replaced some helper functions for creating acl entries; I prefer just
assigning directly to the struct fields--it takes a few more lines, but the
field names provide some documentation that I think makes the result easier

[PATCH] knfsd: nfsd4: relax checking of ACL inheritance bits

The rfc allows us to be more permissive about the ACL inheritance bits we
accept:

"If the server supports a single "inherit ACE" flag that applies to
both files and directories, the server may reject the request
(i.e., requiring the client to set both the file and directory
inheritance flags). The server may also accept the request and
silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag."

Let's take the latter option--the ACL is a complex attribute that could be
rejected for a wide variety of reasons, and the protocol gives us little
ability to explain the reason for the rejection, so erroring out is a
user-unfriendly last resort.

[PATCH] Add debugging feature /proc/timer_list

add /proc/timer_list, which prints all currently pending (high-res) timers,
all clock-event sources and their parameters in a human-readable form.

[PATCH] Add debugging feature /proc/timer_stat

Add /proc/timer_stats support: debugging feature to profile timer expiration.
Both the starting site, process/PID and the expiration function is captured.
This allows the quick identification of timer event sources in a system.

Sample output:

# echo 1 > /proc/timer_stats
# cat /proc/timer_stats

[PATCH] hrtimers: add high resolution timer support

Implement high resolution timers on top of the hrtimers infrastructure and the
clockevents / tick-management framework.  This provides accurate timers for
all hrtimer subsystem users.

[PATCH] i386 prepare nmi watchdog for dynticks

The NMI watchdog implementation assumes that the local APIC timer interrupt is
happening.  This assumption is not longer true when high resolution timers and
dynamic ticks come into play, as they may switch off the local APIC timer
completely.  Take the PIT/HPET interrupts into account too, to avoid false
positives.
