2011-01-14GRETH: resolve SMP issues and other problemsDaniel Hellstrom
Fixes the following: 1. POLL should not enable IRQ when work is not completed 2. No locking between TX descriptor cleaning and XMIT descriptor handling 3. No locking between RX POLL and XMIT modifying control register 4. Since TX cleaning (called from POLL) is running in parallel with XMIT unnecessary locking is needed. 5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is temporarily disabled (in POLL), and when IRQ is shared. 6. IRQ handler clears IRQ status, which is unnecessary 7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1 descriptors were available after a SKB been scheduled by XMIT. Instead the TX queue is stopped first when not enough descriptors are available upon entering XMIT. It was hard to split up this patch in smaller pieces since all are tied together somehow. Note the RX flag used in the interrupt handler does not signal that interrupt was asserted, but that a frame was received. Same goes for TX. Also, IRQ is not asserted when the RX flag is set before enabling IRQ enable until a new frame is received. So extra care must be taken to avoid enabling IRQ and all descriptors are already used, hence dead lock will upon us. See new POLL implementation that enableds IRQ then look at the RX flag to determine if one or more IRQs may have been missed. TX/RX flags are cleared before handling previously enabled descriptors, this ensures that the RX/TX flags are valid when determining if IRQ should be turned on again. By moving TX cleaning from POLL to XMIT in the standard case, removes some locking trouble. Enabling TX cleaning from poll only when not enough TX descriptors are available is safe because the TX queue is at the same time stopped, thus XMIT will not be called. The TX queue is woken up again when enough descriptrs are available. TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will not be enabled until XMIT must wait for free descriptors. Locking RX and XMIT parts of the driver from each other is needed because the RX/TX enable bits share the same register. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-14block: restore multiple bd_link_disk_holder() supportTejun Heo
Commit e09b457b (block: simplify holder symlink handling) incorrectly assumed that there is only one link at maximum. dm may use multiple links and expects block layer to track reference count for each link, which is different from and unrelated to the exclusive device holder identified by @holder when the device is opened. Remove the single holder assumption and automatic removal of the link and revive the per-link reference count tracking. The code essentially behaves the same as before commit e09b457b sans the unnecessary kobject reference count dancing. While at it, note that this facility should not be used by anyone else than the current ones. Sysfs symlinks shouldn't be abused like this and the whole thing doesn't belong in the block layer at all.

The PCI sysfs ROM interface requires an enabling write to access the ROM image, but the default file mode is 0400. The original proposed patch adding sysfs ROM support was a true read-only interface, with the enabling bit coming in as a feature request. I suspect it was simply an oversight that the file mode didn't get updated to match the API.

This functionality is known to be incomplete, so discourage its use in general-purpose kernels. The only reason to use this driver is to support PCI hotplug on CNB20LE- based machines that don't have ACPI, and there are very few such systems.

2011-01-14x86/PCI: don't use native Broadcom CNB20LE driver when ACPI is availableBjorn Helgaas
The broadcom_bus.c quirk was written (without benefit of documentation) to support PCI hotplug on an old system that doesn't have ACPI. As such, we should only use it when the system doesn't have ACPI. If the system does have ACPI and we need the host bridge description, we should get it from the ACPI _CRS method. On machines older than 2008, we currently ignore _CRS, but that doesn't mean we should use broadcom_bus.c. It means we should either (a) do what we've done in the past and assume everything in the PCI gap is routed to bus 0 (so hotplug may not work), or (b) arrange to use _CRS. This patch does (a).

2011-01-14PCI: enable pci=bfsort by default on future Dell systemsNarendra_K@Dell.com
This patch enables pci=bfsort by default on future Dell systems. It reads SMBIOS type 0xB1 vendor specific record and sets pci=bfsort accordingly. Offset Name Length Value Description 04 Flags0 Word Varies Bits 9-10 - 10:9 = 00 Unknown - 10:9 = 01 Breadth First - 10:9 = 10 Depth First - 10:9 = 11 Reserved 1. Any time pci=bfsort has to be enabled on a system, we need to add the model number of the system to the white list. With this patch, that is not required. 2. Typically, model number has to be added to the white list when the system is under development. With this change, that is not required.
