The it8705 chip supports 16-bit fan tachometers in revisions at least
>= 0x03 (Version G). This patch enables 16-bit fan readings on all
revisions >= 0x03 just like the it8712, it8716, and it8718 chips.Signed-off-by: Andrew Paprocki

The it8712 chip supports 16-bit fan tachometers in revisions >= 0x07.
Revisions >= 0x08 dropped support for 8-bit fan divisor registers. The
patch enables 16-bit fan readings on all revisions >= 0x07 just like
the it8716 and it8718 chips.Signed-off-by: Andrew Paprocki

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.Signed-off-by: Jean Delvare

Update w83791d with fan bits in vbat mon register (7.48 of the

Add support for the SCH5027. The differences to the DME1737 are:
- No support for programmable temp offsets
- In auto mode, PWM outputs stay on min value if temp goes below low threshold
and can't be programmed to fully turn off
- Different voltage scaling
- No VID inputSigned-off-by: Juerg Haefliger

I asked legal about the licensing of ftrace.txt, and they told me that,
unless the Documentation directory is specifically set up to handle non
GPL licenses (which it does not appear to be), then it would be best to
put ftrace.txt under the GPL.This patch adds a dual license to ftrace.txt such that it is under both
the FDL and the GPL.Signed-off-by: Steven Rostedt

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

Sysfs has the _ATTR() and _ATTR_RO() macros to make defining extended
form attributes easier. configfs should have something similiar.- _CONFIGFS_ATTR() and _CONFIGFS_ATTR_RO() are the counterparts to the
sysfs macros.
- CONFIGFS_ATTR_STRUCT() creates the extended form attribute structure.
- CONFIGFS_ATTR_OPS() defines the show_attribute()/store_attribute()
operations that call the show()/store() operations of the extended
form configfs_attributes.Signed-off-by: Joel Becker

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).Signed-off-by: Rusty Russell

virtio_ring has the ability to suppress notifications. This prevents
a guest exit for every packet, but we need to set a timer on packet
receipt to re-check if there were any remaining packets.Here are the times for 1G TCP Guest->Host with different timeout
settings (it matters because the TCP window doesn't grow big enough to
fill the entire buffer):Timeout value Seconds Xmit/Recv/Timeout
