Paul E. McKenney 996417d2c4 [PATCH] add success/failure indication to RCU torture test
One issue with the RCU torture test is that the current error flagging can
be lost in dmesg.  This patch adds a "SUCCESS"/"FAILURE" string to the line
that flags the end of the test, where it can easily be seen with "dmesg |
tail" at the end of the test.  Also adds tests of architecture-specific
memory barriers -- or, more likely, of the RCU torture test itself.

 - support vectored and async aio ops unconditionally - this is above

 - remove cifs_read_wrapper.  it was only doing silly checks and
   calling generic_file_write in all cases.
 - use do_sync_read/do_sync_write as read/write operations.  They call
   ->readv/->writev which we now always implemente.
 - add the filemap_fdatawrite calls to writev/aio_write which were
   missing previously compared to plain write.  no idea what the point
   behind them is, but let's be consistent at least..

David S. Miller 381998241f [LLC]: Fix compiler warnings introduced by TX window scaling changes.
Noticed by Olaf Hering.

The comparisons want a u8 here (the data type on the left-hand branch
is a u8 structure member, and the constant on the right-hand branch is
"~((u8) 128)"), but C turns it into an integer so we get:

net/llc/llc_c_ac.c: In function `llc_conn_ac_inc_npta_value':
net/llc/llc_c_ac.c:998: warning: comparison is always true due to limited range of data type
net/llc/llc_c_ac.c:999: warning: large integer implicitly truncated to unsigned type

Fix this up by explicitly recasting the right-hand branch constant
into a "u8" once more.

Ryan Bradetich a137ce8536 [PARISC] Define port->timeout to fix a long msleep in mux.c
This commit is in response to a bug reported by Vesa on the irc channel
a couple of weeks ago.

The bug was that the console would apparently hang (not return) while
using the mux console.

The root cause of this bug is that bash (with readline support) makes a
call to the tcsetattr() glibc function with the argument TCSADRAIN.  This
causes the serial core in the kernel use the uart_wait_until_sent() to be
called. This function verifies the mux transmit queue is empty or calls the
msleep_interruptable() with a calculated timeout value that is dependant
upon the port->timeout variable.

The real problem here is that the port->timeout was not defined so it
was defaulted to 0 and the timeout calculation performs the following
calculation:

char_time = (port->timeout - HZ/50) / port->fifosize;

where char_time is an unsigned long. Since the serial Mux does not use
interrupts, the msleep_interruptable() function waits until the timeout
has been reached ... and when the port->timeout < HZ/50 this timeout will
be a long time. (I have validated that the console will eventually
return ... but it takes quite a while for this to happen).

This patch simply sets the port->timeout on the Mux to HZ/50 to avoid
this long timeout period.

James Bottomley 08dc2ca61e [PARISC] Fix our spinlock implementation
We actually have two separate bad bugs

1. The read_lock implementation spins with disabled interrupts.  This is
completely wrong
2. Our spin_lock_irqsave should check to see if interrupts were enabled
before the call and re-enable interrupts around the inner spin loop.

The problem is that if we spin with interrupts off, we can't receive
IPIs. This has resulted in a bug where SMP machines suddenly spit
smp_call_function timeout messages and hang.

The scenario I've caught is

CPU0 does a flush_tlb_all holding the vmlist_lock for write.
CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for
     read
CPU1 is now spinning with interrupts disabled
CPU0 tries to execute a smp_call_function to flush the local tlb caches

This is now a deadlock because CPU1 is spinning with interrupts disabled
and can never receive the IPI
