2011-06-02perf script: Make printing of dso a separate field optionDavid Ahern
The 'sym' option displays both the function name and the DSO it comes from. Split the display of the dso into a separate option. This allows display of the ip address and symbol without the dso, thus shortening line lengths - and decluttering the output a bit.

2011-06-02perf script: "sym" field really means show IP dataDavid Ahern
Currently the "sym" output field is used to dump instruction pointers and callchain stack. Sample addresses can also be converted to symbols, so the meaning of "sym" needs to be fixed. This patch adds an "ip" option and if it is selected the user can also opt to dump symbols for them. If the user opts to dump IP without syms only the address is shown.

2011-06-02perf stat: clarify unsupported events from uncounted eventsDavid Ahern

2011-06-02ktest: Ignore unset values of the minconfig in config_bisectSteven Rostedt

2011-06-02ktest: Fix result of rebooting the kernelSteven Rostedt
The command that is called that reboots the kernel may fail but the return code is not passed back to the ktest.pl script. This is because a ';' is used between the two commands and if the second command fails, only the first command's return code is returned. Using a '&&' between the two commands fixes this.

2011-06-02ktest: Fix off-by-one in config bisect resultSteven Rostedt
Because in perl the array size returned by $#arr, is the last index and not the actually size of the array, we end the config bisect early, thinking there is only one config left when there are in fact two. Thus the result has a 50% chance of picking the correct config that caused the problem. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2011-06-02[SCSI] Fix oops caused by queue refcounting failureJames Bottomley
In certain circumstances, we can get an oops from a torn down device. Most notably this is from CD roms trying to call scsi_ioctl. The root cause of the problem is the fact that after scsi_remove_device() has been called, the queue is fully torn down. This is actually wrong since the queue can be used until the sdev release function is called. Therefore, we add an extra reference to the queue which is released in sdev->release, so the queue always exists.

2011-06-01net: dm9000: Get the chip in a known good state before enabling interruptsMark Brown
Currently the DM9000 driver requests the primary interrupt before it resets the chip and puts it into a known good state. This means that if the chip is asserting interrupt for some reason we can end up with a screaming IRQ that the interrupt handler is unable to deal with. Avoid this by only requesting the interrupt after we've reset the chip so we know what state it's in. This started manifesting itself on one of my boards in the past month or so, I suspect as a result of some core infrastructure changes removing some form of mitigation against bad behaviour here, even when things boot it seems that the new code brings the interface up more quickly.
