2006-05-21[PATCH] Overrun in isdn_tty.cEric Sesterhenn
This fixes coverity bug id #1237. After the while loop, it is possible for i == ISDN_LMSNLEN. If this happens the terminating '\0' is written after the end of the array.

2006-05-21[PATCH] pci: correctly allocate return buffers for osc callsKristen Accardi
The OSC set and query functions do not allocate enough space for return values, and set the output buffer length to a false, too large value. This causes the acpi-ca code to assume that the output buffer is larger than it actually is, and overwrite memory when copying acpi return buffers into this caller provided buffer. In some cases this can cause kernel oops if the memory that is overwritten is a pointer. This patch will change these calls to use a dynamically allocated output buffer, thus allowing the acpi-ca code to decide how much space is needed.

2006-05-21[PATCH] powerpc: Fix ide-pmac sysfs entryBenjamin Herrenschmidt
It looks like the generic ide code now wants ide_init_hwif_ports() to set the parent struct device into the ide_hw structure (new field ?). Without this, the mac ide code can cause the ide probing code to explode in flames in sysfs registration due to what looks like a stale pointer in there (happens when removing/re-inserting one of the hotswap media bays on some laptops).

2006-05-21[PATCH] matroxfb: fix DVI setup to be more compatiblePaul A. Clarke
There has been a longstanding problem with the Matrox G450 and perhaps other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes running Linux. Higher resolutions and/or higher refresh rates resulted in a very noticably "jittery" display, and sometimes no display, depending on the physical monitor. This patch fixes that problem on the systems I have easy access to... I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32 box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to verify that it didn't obviously break anything. In my testing, I covered single-card, single and dual-head setups using both HD15 and DVI-D signals, on both the IA32 and ppc64 boxes. While everything appeared fine on both boxes, I did encounter one problem: I can't get any signal on the DVI-D output on the ppc64 box. However, this is also the case without my patch. I just noticed that screen-blanking only occurs on the primary display as well. Signed-off-by: Paul A.

With Manfred Spraul <manfred@colorfullife.com> and Andrew Morton <akpm@osdl.org> Bring back this recently-reverted patch, only fixed.

This fixes a byte-swap issue on PPC, found by Zang Roy-r61911 on the powerpc platform.

2006-05-20[PATCH] sata_mv: remove local copy of queue indexesMark Lord
The driver currently keeps local copies of the hardware request/response queue indexes. But it expends significant effort ensuring consistency between the two views, and still gets it wrong after an error or reset occurs. This patch removes the local copies, in favour of just accessing the hardware whenever we need them. Eventually this may need to be tweaked again for NCQ, but for now this works and solves problems some users were seeing.

2006-05-20[PATCH] sata_mv: spurious interrupt workaroundMark Lord
The 60xx chips, and possibly others, incorrectly assert DEV_IRQ interrupts on a regular basis. The cause of this is under investigation (by me and in theory by Marvell also), but regardless we do need to deal with these events. This patch tidies up some interrupt handler code, and ensures that we ignore DEV_IRQ interrupts when the drive still has ATA_BUSY asserted.

2006-05-20[PATCH] sata_mv: chip initialization fixesMark Lord
The interface control register of the 60xx (and later) Marvell chip requires certain bits to always be set when writing to it. These bits incorrectly read-back as zeros, so the pattern must be ORed in with each write of the register. Also, bit 12 should NOT be set (note that Marvell's own driver also had bit-12 wrong here). While we're at it, we also now do pci_set_master() in the init code. Signed-off-by: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] sata_mv: deal with interrupt coalescing interruptsMark Lord
In some systems, it is possible that the BIOS may have enabled interrupt coalescing for the Marvell controllers which support it.

2006-05-20[PATCH] sata_mv: prevent unnecessary double-resetsMark Lord
The mv_err_intr() function is invoked from the driver's interrupt handler, as well as from the timeout function. This patch prevents it from triggering a one-after-the-other double reset of the controller when invoked from the timeout function. This also adds a check for a timeout race condition that has been observed to occur with this driver in earlier kernels. This should not be needed, in theory, but in practice it has caught bugs. Maybe nuke it at a later date. Signed-off-by: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-05-20[PATCH] sky2: allow dual port usageStephen Hemminger
If both ports are receiving on the SysKonnect dual port cards, then it appears the bus interface unit can give an interrupt status for frame before DMA has completed. This leads to bogus frames and general confusion. This is why receive checksumming is also messed up on dual port cards. A workaround for the out of order receive problem is to eliminating split transactions on PCI-X. This version is based of the current linux-2.6.git including earlier patch to disable dual ports.

This fixes two problems triggered by the MMC stack updating clocks: - SPI masters driver should accept a max clock speed of zero; that's one convention for marking idle devices. (Presumably that helps controllers that don't autogate clocks to "off" when not in use.) - There are more than 1000 nanoseconds per millisecond; setting the clock down to 125 KHz now works properly.
