[PATCH] Call exit_itimers from do_exit, not __exit_signal
When I originally moved exit_itimers into __exit_signal, that was the only
place where we could reliably know it was the last thread in the group
dying, without races. Since then we've gotten the signal_struct.live
counter, and do_exit can reliably do group-wide cleanup work.
This patch moves the call to do_exit, where it's made without locks. This
avoids the deadlock issues that the old __exit_signal code's comment talks
about, and the one that Oleg found recently with process CPU timers.

[PATCH] cpufreq: fix pending powernow timer stuck condition
AMD recently discovered that on some hardware, there is a race condition
possible when a C-state change request goes onto the bus at the same
time as a P-state change request.
Both requests happen, but the southbridge hardware only acknowledges the
C-state change. The PowerNow! driver is then stuck in a loop, waiting
for the P-state change acknowledgement. The driver eventually times
out, but can no longer perform P-state changes.
It turns out the solution is to resend the P-state change, which the
southbridge will acknowledge normally.

[PATCH] ppc64: Fix pages marked dirty abusively
While working on 64K pages, I found this little buglet in our
update_mmu_cache() implementation.
The code calls __hash_page() passing it an "access" parameter (the type
of access that triggers the hash) containing the bits _PAGE_RW and
_PAGE_USER of the linux PTE. The latter is useless in this case and the
former is wrong. In fact, if we have a writeable PTE and we pass
_PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty
that way, by hash faulting !dirty) which is not what we want.
In fact, the correct fix is to always pass 0. That means that only
read-only or already dirty read write PTEs will be preloaded. The
(hopefully rare) case of a non dirty read write PTE can't be preloaded
this way, it will have to fault in hash_page on the actual access.

[PATCH] Three one-liners in md.c
The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts. This would
only happen when resync/recovery is happening.
This patch fixes three vaguely related bugs.
1/ The recent change to use kthreads got the setting of the
process name wrong. This fixes it.
2/ The recent change to use kthreads lost the ability for
md threads to be signalled with SIG_KILL. This restores that.
3/ There is a long standing bug in that if:
- An array needs recovery (onto a hot-spare) and
- The recovery is being blocked because some other array being
recovered shares a physical device and
- The recovery thread is killed with SIG_KILL
Then the recovery will appear to have completed with no IO being
done, which can cause data corruption.
This patch makes sure that incomplete recovery will be treated as
incomplete.
Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered. Thus the current 2.6.14-rc
kernels are not susceptible to data corruption. Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur. It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

That code was using tasklist_lock to check for a race with __exit_signal

I'm using the Vesa FB driver. When the machine has been idle for some
time and the driver attempts to powerdown the display, rather than the
display going blank, it goes gray with several strange lines. When I
hit the "shift" key or other-wise wake up the display, the old video

vesafb recently added a blank method which has only 2 states, powerup and
powerdown. The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.

[PATCH] USB: fix bug in handling of highspeed usb HID devices
During the development of an USB device I found a bug in the handling of
Highspeed HID devices in the kernel.
What happened?
Highspeed HID devices are correctly recognized and enumerated by the
kernel. But even if usbhid kernel module is loaded, no HID reports are
received by the kernel.
The output of the hardware USB analyzer told me that the host doesn't
even poll for interrupt IN transfers (even the "interrupt in" USB
transfer are polled by the host).
After some debugging in hid-core.c I've found the reason.
In case of a highspeed device, the endpoint interval is re-calculated in
driver/usb/input/hid-core.c:
line 1669:
/* handle potential highspeed HID correctly */
interval = endpoint->bInterval;
if (dev->speed == USB_SPEED_HIGH)
interval = 1 << (interval - 1);
Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6).
This new calculated value of "interval" is used as input for
usb_fill_int_urb:
line 1685:
usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0,
hid_irq_in, hid, interval);
Unfortunately the same calculation as above is done a second time in
usb_fill_int_urb in the file include/linux/usb.h:
line 933:
if (dev->speed == USB_SPEED_HIGH)
urb->interval = 1 << (interval - 1);
else
urb->interval = interval;
This means, that if the endpoint descriptor (of a high speed device)
specifies e.g. bInterval = 7, the urb->interval gets the value:
hid-core.c: interval = 1 << (7-1) = 0x40 = 64
urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow
Because of this the value of urb->interval is sometimes negative and is
rejected in core/urb.c:
line 353:
/* too small? */
if (urb->interval <= 0)
return -EINVAL;
The conclusion is, that the recalculaton of the interval (which is
necessary for highspeed) should not be made twice, because this is
simply wrong. ;-)
Re-calculation in usb_fill_int_urb makes more sense, because it is the
most general approach. So it would make sense to remove it from
hid-core.c.
Because in hid-core.c the interval variable is only used for calling
usb_fill_int_urb, it is no problem to remove the highspeed
re-calculation in this file.

[PATCH] SVGATextMode fix
Fix bug 5441.
I didn't know about messy programs like svgatextmode... Couldn't this be
integrated in some linux/drivers/video/console/svgacon.c ?... So because
of the existence of the svgatextmode program, the kernel is not supposed to
touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ?
Disabling the check in vgacon_resize() might help indeed, but I'm really
not sure whether it will work for any chipset: in my patch, CRT registers
are set at each console switch, since stty rows/cols apply to consoles
separately...
The attached solution is to keep the test, but if it fails, we assume that
the caller knows what it does (i.e. it is svgatextmode) and then disable
any further call to vgacon_doresize. Svgatextmode is usually used to
_expand_ the display, not to shrink it. And it is harmless in the case of
a too big stty rows/cols: the display will just be cropped. I tested it on
my laptop, and it works fine with svgatextmode.
A better solution would be that svgatextmode explicitely tells the kernel
not to care about video timing, but for this an interface needs be defined
and svgatextmode be patched.

[PATCH] list: add missing rcu_dereference on first element
It seems that all the list_*_rcu primitives are missing a memory barrier

#define list_for_each_rcu(pos, head) \
for (pos = (head)->next; prefetch(pos->next), pos != (head); \

It will go something like:

barrier given by rcu_dereference(pos->next)

In fact, if "do stuff" were also dereferencing pos and relying on
list_for_each_rcu to provide the barrier then it may also break.

driver to compile on systems that doesn't support ISA, like x86_64. The
driver really doesn't depend on ISA, it does some ISA stuff in the
initialization code, since the driver supports both ISA and PCI cards. So
the driver should depend on ISA_DMA_API to build on all systems, and this
will not hurt PCI at all.

[SPARC64]: Fix powering off on SMP.
Doing a "SUNW,stop-self" firmware call on the other cpus is not the
correct thing to do when dropping into the firmware for a halt,
reboot, or power-off.
For now, just do nothing to quiet the other cpus, as the system should
be quiescent enough. Later we may decide to implement smp_send_stop()
like the other SMP platforms do.
