* PCI: Remove 3 incorrect MSI quirks.David Miller2007-11-05
| | | | | | | | | | | | | | | | | | | | | Now that we have dealt with the real issue, in that some ATI SATA and USB controllers needed the INTX_DISABLE quirk, we can remove these AMD chipset global MSI disabling quirks. This reverts three changesets: 4be8f906435a6af241821ab5b94b2b12cb7d57d8 (PCI: disable MSI on RS690) aea6a433f50cd89b9cbd10850fd0b32f961f9883 (PCI: disable MSI on RD580) f122392f679ebed39db08074f935d770504623eb (PCI: disable MSI on RX790) This is based upon testing and feedback from Shane Huang <Shane.Huang@amd.com>.

* PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.David Miller2007-11-05
| | | | | | | | | | | | | | | | | | A reasonably common problem with some devices is that they will disable MSI generation when the INTX_DISABLE bit is set in the PCI_COMMAND register. Quirk this explicitly, guarding the pci_intx() calls in msi.c with this quirk indication. The first entries for this quirk are for 5714 and 5780 Tigon3 chips, and thus we can remove the workaround code from the tg3.c driver. Signed-off-by: David S.

* PCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.David Miller2007-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the fix for the following problem: https://bugzilla.redhat.com/show_bug.cgi?id=227657 The bnx2 device 5706 complains about MSI not working behind a ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem: e3008dedff4bdc96a5f67224cd3d8d12237082a0: "PCI: disable MSI by default on systems with Serverworks HT1000 chips" was not entirely correct, and has been reverted. MSI does not work on the PCIX bus because the BIOS did not set the HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the bridge. We use the existing quirk_msi_ht_cap() to detect the problem and disable MSI in all buses behind it.

It is - monotonic - allows very fast reading - architecture guarantees at least microsecond stepping - available as part of the architecture We should announce the rate of tod as 400 to be in sync with the description found in clocksource.h: "400-499:Perfect The ideal clocksource.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsgiucv is a driver that relies on iucv to work properly. If iucv ans smsgiucv are compiled into the kernel and run on an lpar the following scenario happens: iucv is initialized early as a subsystem. It checks for z/VM and returns with EPROTONOTSUPPORT. Later smsgiucv tries to run driver_register with iucv_bus as bus. As this bus is not initialized the driver core and list debugging issue several warnings and oopses. Solution is to let smsgiucv also check for z/VM and return EPROTONOTSUPPORT as well.

The per cpu freelist may contain objects and in that situation we may overwrite the per cpu freelist pointer loosing objects. This only occurs if we find that the concurrently allocated slab fits our allocation needs. If we simply always deactivate the slab then the freelist will be properly reintegrated and the memory leak will go away.

If this was not an initial login, but was a login after a disconnect with the server, other I/O requests could attempt to be processed before the login occured. These I/O requests would fail, sometimes resulting in filesystems getting marked read-only. To address this we can set the request_limit to 0 while doing the login and add an exception where login requests, along with task management events, are always passed to the server. There is a case where the request_limit had already reached 0 would result in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this has also been fixed by this patch.

The old (fixed by Linus) /proc/ interface still works, but I'd like to get it using the new one. This patch fixes rtc-cmos to ignore the two upper bits when reading the BCD mday (day of month) register from CMOS. Some systems (eg. mine) seem to have the top bit set to "1" for some reason. The older /proc/ interface ignores the upper bits, and so we should too.

| * | | Deadline iosched: Reset batch for ordered requestsAaron Carroll2007-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The deadline I/O scheduler does not reset the batch count when starting a new batch at a higher-sectored request. This means the second and subsequent batch in the same data direction will never exceed a single request in size whenever higher-sectored requests are pending. This patch gives new batches in the same data direction as old ones their full quota of requests by resetting the batch count.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

This patch therefore either replaces them with #include <linux/scatterlist.h> or simply removes them if they were unused.
