The EEPROM is read via programmable I/O pins. When the driver is compiled -Os, the CPU can speculatively read the I/O value before it is valid. This patch fixes the problem. Signed-off-by:

We can sometimes trigger parity errors due to processor speculative reads to our write-combined memory (mostly seen on Woodcrest). Add a stats counter for these. Factored out the sendbuffererror buffer cancellation code so it can be used in the new handling; suppress likely subsequent error messages if within two jiffies of the cancellation. Also restore 2 dropped TXE lines on hwe_bitsextant noticed while debugging. Signed-off-by:

The system must be powercycled to clear a HT CRC error; reloading the driver is not enough. Signed-off-by:

Fixed mismatch in linkstate/trainingstate shifts and masks in the IPATH_IBSTATE_MASK macro. It kept some linktrainingstates from being printed correctly in debug; no functionality issue unless I misread the code. Signed-off-by:

iSER uses the DMA mapping api to map the page holding the SCSI command data to the HCA DMA address space. When the command data is not aligned for RDMA, the data is copied to/from an allocated buffer which in turn is used for executing this command. The pages associated with the command must be unmapped before being touched. Signed-off-by:

iSER uses a data transaction object (struct iser_dto) as part of its IB data descriptors (struct iser_desc) management. It also uses a hierarchy of connection structures pointing to each other. A DTO may exist even after the iscsi_iser connection pointed by it is destroyed (eg one that is bound to a post receive buffer which was flushed by the IB HW). Hence DTOs need point to the lowest connection, which is struct iser_conn. Signed-off-by:

If the allocation of mr fails, then c2_reg_phys_mr() leaks the page_list array it allocated earlier. This was Coverity CID #1413. Signed-off-by: -

Another NULL dereference spotted by the Coverity checker (cid #1395): In case we can't alloc the vq_req, we goto bail1, where we call vq_req_free(c2dev, vq_req); which then dereferences vq_req. Signed-off-by:

Ingo Oeser pointed out that because current expands to an inline function it is more space efficient and somewhat faster to simply keep a cached copy of current in another variable. This patch implements that for the de_thread function. (akpm: saves nearly 100 bytes of text on x86) Signed-off-by:

With the patches flying between Oleg and myself somehow this temporary debug code got left in pid.c. It was never intended to make it to the stable kernel. Signed-off-by:
-
Eric W. Biederman authored
In de_thread we move pids from one process to another, a rather ugly case. The function transfer_pid makes it clear what we are doing, and makes the action atomic. This is useful we ever want to atomically traverse the process group and session lists, in a rcu safe manner. Even if the atomic properties this change should be a win as transfer_pid should be less code to execute than executing both attach_pid and detach_pid, and this should make de_thread slightly smaller as only a single function call needs to be emitted. The only downside is that the code might be slower to execute as the odds are against transfer_pid being in cache. Signed-off-by:
