forcedeth: setup wake-on-lan before shutting down") that makes network
adapters integrated into the NVidia MCP55 chipsets fail to work in kexeced
kernels.  The problem appears to be that if the adapter is put into D3_hot

http://marc.info/?l=linux-kernel&m=121900062814967&w=4).  Therefore, only

sched: fix process time monotonicity

Spencer reported a problem where utime and stime were going negative despite
the fixes in commit b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa. The suspected
reason for the problem is that signal_struct maintains it's own utime and
stime (of exited tasks), these are not updated using the new task_utime()
routine, hence sig->utime can go backwards and cause the same problem
to occur (sig->utime, adds tsk->utime and not task_utime()). This patch
fixes the problem

TODO: using max(task->prev_utime, derived utime) works for now, but a more
generic solution is to implement cputime_max() and use the cputime_gt()
function for comparison.

PCI: fix pbus_size_mem() resource alignment for CardBus controllers

Commit 884525655d07fdee9245716b998ecdc45cdd8007 ("PCI: clean up resource
alignment management") changed the resource handling to mark how a
resource was aligned on a per-resource basis.

Thus, instead of looking at the resource number to determine whether it
was a bridge resource or a regular resource (they have different
alignment rules), we should just ask the resource for its alignment
directly.

The reason this broke only cardbus resources was that for the other
types of resources, the old way of deciding alignment actually still
happened to work.  But CardBus bridge resources had been changed by
commit 934b7024f0ed29003c95cef447d92737ab86dc4f ("Fix cardbus resource

13 years agox86: Change warning message in TSC calibration.

x86: Change warning message in TSC calibration.

When calibration against PIT fails, the warning that we print is misleading.
In a virtualized environment the VM may get descheduled while calibration
or, the check in PIT calibration may fail due to other virtualization
overheads.

The warning message explicitly assumes that calibration failed due to SMI's
which may not be the case. Change that to something proper.

bnx2x: Accessing un-mapped page

The allocated RX buffer size was 64 bytes bigger than the PCI mapped
size with no good reason. If the packet was actually using the buffer up
to its limit and if the last 64 bytes of the buffer crossed 4KB boundary
then an unmapped PCI page was accessed. The fix is to use only one
parameter for the buffer size - there is no need to differentiate
between the buffer size and the PCI mapping size since the extra 64

Mauro Carvalho Chehab [Wed, 3 Sep 2008 20:11:53 +0000 (17:11 -0300)]
V4L/DVB (8751): vivi: Fix some issues at vivi register routine

This patch fixes several small issues at vivi register routines:

1) minor and n_devs should be unsigned;
2) n_devs = 0 were not properly handled;
3) if n_devs specify a high number, the driver would just roll back and
won't register any device. The proper behaviour is to keep all succeded
devices registered;
4) both n_devs and minor were using 0 as permissions. Better to have
them with 0444.

With the current patch, if n_devs specify a very large value, it will
register all possible devices. For example, on a machine without any
other V4L drivers loaded, with this patch, we will have something like:

vivi: V4L2 device registered as /dev/video0
vivi: V4L2 device registered as /dev/video1
vivi: V4L2 device registered as /dev/video2
...
vivi: V4L2 device registered as /dev/video31
video_register_device_index: get_index failed
Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded.

5) The number of allocated devices on success is now kept at n_devs:

$ cat /sys/module/vivi/parameters/n_devs
32
