2008-08-06hwmon: (w83627hf) Drop reset module parameterJean Delvare
Drop the reset parameter of the w83627hf driver. It seems it wasn't that useful. It was dropped from the Linux 2.4 version of this driver back in July 2004. The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode. Now that the driver creates pwmN_enable sysfs files, users will be able to use these files instead, which is way less agressive.

2008-08-01kgdb: fix kgdb_validate_break_address to perform a mem writeJason Wessel
A regression to the kgdb core was found in the case of using the CONFIG_DEBUG_RODATA kernel option. When this option is on, a breakpoint cannot be written into any readonly memory page. When an external debugger requests a breakpoint to get set, the kgdb_validate_break_address() was only checking to see if the address to place the breakpoint was readable and lacked a write check. This patch changes the validate routine to try reading (via the breakpoint set request) and also to try immediately writing the break point. If either fails, an error is correctly returned and the debugger behaves correctly. Then an end user can make the descision to use hardware breakpoints. Also update the documentation to reflect that using CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

2008-07-29lguest: turn Waker into a thread, not a processRusty Russell
lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

2008-07-29lguest: Adaptive timeoutRusty Russell
Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen. This gives slightly worse results, but doesn't need tweaking when GSO is introduced. 500 usec 19.1887 xmit 561141 recv 1 timeout 559657 Dynamic (278) 20.1974 xmit 214510 recv 5 timeout 214491 usec 278 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
