2011-01-10cxgb4vf: fix mailbox data/control coherency domain raceCasey Leedom
For the VFs, the Mailbox Data "registers" are actually backed by T4's "MA" interface rather than PL Registers (as is the case for the PFs). Because these are in different coherency domains, the write to the VF's PL-register-backed Mailbox Control can race in front of the writes to the MA-backed VF Mailbox Data "registers". So we need to do a read-back on at least one byte of the VF Mailbox Data registers before doing the write to the VF Mailbox Control register.

2011-01-10qlcnic: fix flash fw version readamit salecha
Driver is reading flash fw version from defined address, this address may be invalid. Indeed Driver should read address for fw version through flash layout table. Flash layout table has defined region and address for fw version address should be read from fw image region. Driver has check for old firmware, this bug can cause driver load fail.

Dan Rosenberg pointed out that there were some signed comparison bugs in the phonet protocol. http://marc.info/?l=full-disclosure&m=129424528425330&w=2 The problem is that we check for array overflows but "protocol" is signed and we don't check for array underflows.

2011-01-10i2c: Constify i2c_client where possibleJean Delvare

2011-01-10i2c-algo-bit: Complain about masters which can't read SCLJean Delvare
The I2C specification explicitly describes both SDA and SCL as bidirectional lines. An I2C master with a read-only SCL is thus not compliant. If a slow slave stretches the clock, errors will happen, so the bus can't be considered as reliable. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2011-01-10i2c-algo-bit: Refactor adapter registrationJean Delvare
Use a function pointer to decide whether to call i2c_add_adapter or i2c_add_numbered_adapter. This makes the code more compact than the current strategy of having the common code in a separate function. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2011-01-10IB/srp: consolidate hot-path variables into cache linesDavid Dillow

2011-01-10IB/srp: stop sharing the host lock with SCSIBart Van Assche

2011-01-10IB/srp: reduce lock coverage of command completionBart Van Assche
We only need the lock to cover list and credit manipulations, so push those into srp_remove_req() and update the call chains. We reorder the request removal and command completion in srp_process_rsp() to avoid the SCSI mid-layer sending another command before we've released our request and added any credits returned by the target. This prevents us from returning HOST_BUSY unneccesarily.

2011-01-10IB/srp: reduce local coverage for command submission and EHBart Van Assche
We only need locks to protect our lists and number of credits available. By pre-consuming the credit for the request, we can reduce our lock coverage to just those areas. If we don't actually send the request, we'll need to put the credit back into the pool.

2011-01-10IB/srp: don't move active requests to their own listBart Van Assche
We use req->scmnd != NULL to indicate an active request, so there's no need to keep a separate list for them. We can afford the array iteration during error handling, and dropping it gives us one less item that needs lock protection.

2011-01-10hostap_cs: fix sleeping function called from invalid contextStanislaw Gruszka
pcmcia_request_irq() and pcmcia_enable_device() are intended to be called from process context (first function allocate memory with GFP_KERNEL, second take a mutex). We can not take spin lock and call them. It's safe to move spin lock after pcmcia_enable_device() as we still hold off IRQ until dev->base_addr is 0 and driver will not proceed with interrupts when is not ready.

2011-01-10ipw2200: Check for -1 INTA in tasklet too.Indan Zupancic
This is an attempt to fix a long standing open bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334 The interrupt handler checks for INTA being -1, apparently that means that the hardware is gone. But the interrupt handler defers actual interrupt processing to a tasklet. By the time the tasklet is run and checks INTA again, the hardware might be gone and INTA be -1, which confuses the driver because all event bits are set. The patch applies to 2.6.37.

P54_HDR_FLAG_DATA_OUT_SEQNR is meant to tell the firmware that "the frame's sequence number has already been set by the application."
