This patch modifies the I/O resource allocation behavior of FUSION driver.

2008-02-11[SCSI] MegaRAID driver management char device moved to miscThomas Horsten
The MegaRAID driver's common management module (megaraid_mm.c) creates a char device used by the management tool "megarc" from LSI Logic (and possibly other management tools). In 2.6 with udev, this device doesn't get created because it is not registered in sysfs. I first fixed this by registering a class "megaraid_mm", but realized that this should probably be moved to misc devices, instead of taking up a char major. This is because only 1 device is used, even if there are multiple adapters - the minor is never used (the adapter info is in the ioctl block sent to the driver, not detected based on the minor number as one might think). So it is a complete waste to have an entire major taken by this. So it now uses a misc device which I named "megadev0" (the name that megarc expects), and has a dynamic minor (previoulsy a dynamic major was used). I have tested this on my own system with the megarc tool, and it works just as fine as before (only now the device gets created correctly by udev).

2008-02-11[SCSI] advansys: fix overrun_buf aligned bugFUJITA Tomonori
struct asc_dvc_var needs overrun buffer to be placed on an 8 byte boundary. advansys defines struct asc_dvc_var: struct asc_dvc_var { ... uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8); The problem is that struct asc_dvc_var is placed on shost->hostdata. So if the hostdata is not on an 8 byte boundary, the advansys crashes. The hostdata is placed on a sizeof(unsigned long) boundary so the 8 byte boundary is not garanteed with x86_32. With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by chance, but with the current git, it's not. This patch removes overrun_buf static array and use kzalloc.

2008-02-11Use proper abstractions in quirk_intel_irqbalanceMatthew Wilcox
Since we may not have a pci_dev for the device we need to access, we can't use pci_read_config_word. But raw_pci_read is an internal implementation detail; it's better to use the architected pci_bus_read_config_word interface. Using PCI_DEVFN instead of a mysterious constant helps reassure everyone that we really do intend to access device 8. [ Thanks to Grant Grundler for pointing out to me that this is exactly what the write immediately above this is doing -- enabling device 8 to respond to config space cycles. - Matthew Grant also says: "Can you also add a comment which points at the Intel documentation? The 'Intel E7320 Memory Controller Hub (MCH) Datasheet' at http://download.intel.com/design/chipsets/datashts/30300702.pdf Page 69 documents register F4h (DEVPRES1).

2008-02-11DM9000: Update retry count whilst identifying chipBen Dooks

2008-02-11DM9000: Remove barely used SROM array read.Ben Dooks
The srom array in the board data is only being used in the device probe routines. The probe also only uses the first 6 bytes of an array we spend 512ms reading 128 bytes from. Change to reading the MAC area directly to the MAC address structure. As a side product, we rename the read_srom_word to dm9000_read_eeprom to bring it into line with the rest of the driver. No change is made to the delay in this function, which will be dealt with in a later patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Use msleep() instead of udelay()Ben Dooks
We can use sleeping functions when reading and writing the PHY registers, so let us sleep instead of busy waiting for the PHY.

2008-02-11DM9000: Do not sleep with spinlock and IRQs heldBen Dooks
The phy read and write routines call udelay() with the board lock held, and with the posibility of IRQs being disabled. Since these delays can be up to 500usec, and are only required as we have to save the chip's address register. To improve the behaviour, hold the lock whilst we are writing and then restore the state before the delay and then repeat the process once the delay has happened.

2008-02-11DM9000: Remove old timer based poll routinesBen Dooks
Remove the timer based MII phy polling, as this is currently broken with the new EEPROM code that now uses mutexes to protect the phy access. This will need to be replaced in the future by some form of mutex safe mechanism for reading the MII phy status. The replacement has not been done here as changing this patch, which is early in the sequence has quite a knock-on effect. Once this series is merged, then a new presentation of an patch to poll the MII link status can be added. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Pass IRQ flags via platform resourcesBen Dooks
Use the flags in the IRQ resource to specify the type of IRQ being requested, so that systems which do not have level-based interrupts, or change the interrupt in some other way can specify this without making an #ifdef mess in the driver. This is specifically designed to undo the change in commit 4e4fc05a2b6e7bd2e0facd96e0c18dceb34d9349 which hardwires the type for everyone but blackfin to IRQT_RISING, which breaks all a number of Simtec boards which use (and setup in the bootloader) active low IRQs. Note, although there where originally objections due to the use of IORESOURCE_IRQ and IRQT_ flags not sharing the same definition, at least <include/linux/interrupt.h> notes these are the same.
