* [PATCH] ide: touch softlockup detector during pioAndrew Morton2006-02-161-0/+3
| | | | | | | | | | We're getting some softlockup false positives during heavy PIO operations. So poke the lockup detector.

* [PATCH] neofb: avoid resetting display config on unblank (v2)Christian Trefzer2006-02-161-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were two mistakes in the register-read-on-(un)blank approach. - First, without proper register (un)locking the value read back will always be zero, and this is what I missed entirely until just now. Due to this, the logic could not be verified at all and I tried some bogus checks which are completely stupid. - Second, the LCD status bit will always be set to zero when the backlight has been turned off. Reading the value back during unblank will disable the LCD unconditionally, regardless of the state it is supposed to be in, since we set it to zero beforehand. So this is what we do now: - create a new variable in struct neofb_par, and use that to determine whether to read back registers (initialized to true) - before actually blanking the screen, read back the register to sense any possible change made through Fn key combo - use proper neoUnlock() / neoLock() to actually read something - every call to neofb_blank() determines if we read back next time: blanking disables readback, unblanking (FB_BLANK_UNBLANK) enables it This should give us a nice and clean state machine. Has been thoroughly tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached CRT in all possible combinations of LCD/CRT on/off. I changed the config via Fn key, let the console blank, unblanked by keypress - works flawlessly. Signed-off-by: Christian Trefzer <ctrefzer@gmx.de> Cc: "Antonino A.

* [PATCH] neofb: avoid resetting display config on unblankChristian Trefzer2006-02-151-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix issues with the NeoMagic framebuffer driver. It nicely complements my previous fix already in linus' tree. The only thing missing now is that the external CRT will not be activated at neofb init when external-only is selected, either by register read or module/kernel parameter. Testing was done on a Dell Latitude CPi-A/NM2200 chip. Previous behaviour: - before booting linux, set the preferred display config X via FN+F8 - boot linux, neofb stores the register values in a private variable - change the display config to Y via keystroke - leave the machine in peace until display is blanked - touching any key will result in display config X being restored - booting up, the BIOS will acknowledge config Y, though... Current behaviour: At the time of unblanking, config Y is honoured because we now read back register contents instead of just overwriting them with outdated values.

* [PATCH] Fix NULL pointer dereference in isdn_tty_at_coutKarsten Keil2006-02-151-2/+2
| | | | | | | | | | | The changes in the tty related code introduced wrong parenthesis in a if condition in the isdn_tty_at_cout function. This caused access to index -1 in the dev->drv[] array.

* [PATCH] HPET: handle multiple ACPI EXTENDED_IRQ resourcesBjorn Helgaas2006-02-151-13/+9Star
| | | | | | | | | | | | | | | | | | | | | | When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources, we overwrote hdp->hd_nirqs every time we found one. So the driver worked when all the IRQs were described in a single EXTENDED_IRQ resource, but failed when multiple resources were used. (Strictly speaking, I think the latter is actually more correct, but both styles have been used.) Someday we should remove all the ACPI stuff from hpet.c and use PNP driver registration instead. But currently PNP_MAX_IRQ is 2, and HPETs often have more IRQs.

* [PATCH] tty reference count fixPaul Fulghum2006-02-151-4/+3Star
| | | | | | | | | | | | | | | | | | | | | | Fix hole where tty structure can be released when reference count is non zero. Existing code can sleep without tty_sem protection between deciding to release the tty structure (setting local variables tty_closing and otty_closing) and setting TTY_CLOSING to prevent further opens. An open can occur during this interval causing release_dev() to free the tty structure while it is still referenced. This should fix bugzilla.kernel.org [Bug 6041] New: Unable to handle kernel paging request In Bug 6041, tty_open() oopes on accessing the tty structure it has successfully claimed. Bug was on SMP machine with the same tty being opened and closed by multiple processes, and DEBUG_PAGEALLOC enabled.

| * IPoIB: Yet another fix for send-only joinsRoland Dreier2006-02-111-5/+10
| | | | | | | | | | | | | | | | | | | | | | Even after the last fix, it's still possible for a send-only join to start before the join for the broadcast group has finished. This could cause us to create a multicast group using attributes from the broadcast group that haven't been initialized yet, so we would use garbage for the Q_Key, etc. Fix this by waiting until the broadcast group's attached flag is set before starting send-only joins.
