2014-05-27mei: me: read H_CSR after asserting resetTomas Winkler
According the spec the host should read H_CSR again after asserting reset H_RST to ensure that reset was read by the firmware Cc: stable@vger.kernel.org Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-05-27mei: me: fix hw ready reset flowTomas Winkler
We cleared H_RST for H_CSR on spurious interrupt generated when ME_RDY while cleared and not while ME_RDY is set. The spurious interrupt is not delivered on all platforms in this case the driver may fail to initialize.

2014-05-27uio: fix vma io range check in mmapBin Wang
the vma range size is always page size aligned in mmap, while the real io space range may not be page aligned, thus leading to range check failure in the uio_mmap_physical(). for example, in a case of io range size "mem->size == 1KB", and we have (vma->vm_end - vma->vm_start) == 4KB, due to "len" is aligned to page size in do_mmap_pgoff(). now fix this issue by align mem->size to page size in the check.

2014-05-27drivers: uio_dmem_genirq: Fix memory leak in uio_dmem_genirq_probe()Daeseok Youn
When platform_get_irq() is failed after "priv" allocated, it need to free "priv". But the label of bad0 doesn't try to free about "priv". So this patch changes that lable to "bad1". But "bad1" has pm_runtime_disable() call, this function should be called when uio_register_device() is failed. So it is moved into handling error for uio_register_device().

2014-05-27w1: do not unlock unheld list_mutex in __w1_remove_master_device()Alexey Khoroshilov
w1_process_callbacks() expects to be called with dev->list_mutex held, but it is the fact only in w1_process(). __w1_remove_master_device() calls w1_process_callbacks() after it releases list_mutex. The patch fixes __w1_remove_master_device() to acquire list_mutex for w1_process_callbacks(). Found by Linux Driver Verification project (linuxtesting.org).

2014-05-27PCI: Test for std config alias when testing extended config spaceAlex Williamson
When a PCI-to-PCIe bridge is stacked on a PCIe-to-PCI bridge, we can have PCIe endpoints masked by a conventional PCI bus. This makes the extended config space of the PCIe endpoint inaccessible. The PCIe-to-PCI bridge is supposed to handle any type 1 configuration transactions where the extended config offset bits are non-zero as an Unsupported Request rather than forward it to the secondary interface. As noted here, there are a couple known offenders to this rule. These bridges drop the extended offset bits, resulting in the conventional config space being aliased many times across the extended config space. For Intel NICs, this alias often seems to expose a bogus SR-IOV cap. Stacking bridges may seem like an uncommon scenario, but note that any conventional PCI slot in a modern PC is already the secondary interface of an onboard PCIe-to-PCI bridge. The user need only add a PCI-to-PCIe adapter and PCIe device to encounter this problem. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2014-05-27w1: optional bundling of netlink kernel repliesDavid Fries
Applications can submit a set of commands in one packet to the kernel, and in some cases it is required such as reading the temperature sensor results. This adds an option W1_CN_BUNDLE to the flags of cn_msg to request the kernel to reply in one packet for efficiency. The cn_msg flags now check for unknown flag values and return an error if one is seen. See "Proper handling of unknown flags in system calls" http://lwn.net/Articles/588444/ This corrects the ack values returned as per the protocol standard, namely the original ack for status messages and seq + 1 for all others such as the data returned from a read. Some of the common variable names have been standardized as follows. struct cn_msg *cn struct w1_netlink_msg *msg struct w1_netlink_cmd *cmd struct w1_master *dev When an argument and a function scope variable would collide, add req_ to the argument.

2014-05-27connector: allow multiple messages to be sent in one packetDavid Fries
This increases the amount of bundling to reduce the number of packets sent. For the one wire use there can be multiple struct w1_netlink_cmd in a struct w1_netlink_msg and multiple of those in struct cn_msg, and with this change multiple of those in a struct nlmsghdr, and at each level the len identifies there being multiple of the next.

2014-05-27driver core: dev_get_drvdata: Don't check for NULL devJean Delvare
There is no point in calling dev_get_drvdata without a valid device. So checking for dev == NULL is pointless. If such a check is ever needed - which I doubt - the driver should do it before calling dev_get_drvdata. We were returning NULL if dev was NULL, which the caller certainly did not expect anyway, so that was only delaying the crash if the caller is not paying attention.
