[CIFS] Missing flag on negprot needed for some servers to force packet signing
A related signature issue that I came across.
There's a bug in win2k that when NT error codes are not negotiated, the
server doesn't response that signatures are mandatory. Since there's
(currently) no way turn on signatures in such case, I had to force NT
error codes, so that this bug will not occur

The IB CM uses an idr for local id allocations, with a running counter

1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied
This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.
As a fix, remember the last id allocated and start immediately above it.
This also fixes a problem with the old code, where next_id might
overflow and become negative.

x86_64: vsyscall time() fix
The vsyscall time() function basically returns the second portion of
xtime directly. This however means that there is about a ticks worth of
time each second where time() will return a second value less then what
gettimeofday() does.
Additionally, this window where vtime() is behind vgettimeofday() grows
when dynticks is enabled, so its probably good to get this in before
dynticks lands.
Big thanks to Sripathi for noticing this issue and creating a test case
to work with!
This patch changes the vtime() implemenation to call vgettimeofday(),
much as syscall time() implementation calls gettimeofday().
Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.
Since this afflicts many serial drivers, extract the common code to a
library function (uart_console_write) and arrange for each driver to
supply a "putchar" function.

which has a testcase involving signal handling that crashes quite readily.
Inspecting the code I believe what happens is that signal handling can become
confused when it is invoked on return from an interrupt, if the contents of
P0 and R0 at the time of the interrupt happen to be such that P0 is larger
than zero (indicating to the signal code that we're in a syscall), and R0
happens to have a value of something like -EINTR or -ERESTARTSYS.
Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The
testcase now seems to run without problems.

Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.
This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
getting them indirectly
Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
they don't need sched.h
b) sched.h stops being dependency for significant number of files:
on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
after patch it's only 3744 (-8.3%).
