2011-07-19xen/pciback: Cleanup the driver based on checkpatch warnings and errors.Konrad Rzeszutek Wilk
Checkpatch found some extra warnings and errors. This mega patch fixes them all in one big swoop. We also spruce up the pcistub_ids to use DEFINE_PCI_DEVICE_TABLE macro (suggested by Jan Beulich). Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-07-19xen/pciback: xen pci backend driver.Konrad Rzeszutek Wilk
This is the host side counterpart to the frontend driver in drivers/pci/xen-pcifront.c. The PV protocol is also implemented by frontend drivers in other OSes too, such as the BSDs. The PV protocol is rather simple. There is page shared with the guest, which has the 'struct xen_pci_sharedinfo' embossed in it. The backend has a thread that is kicked every-time the structure is changed and based on the operation field it performs specific tasks: XEN_PCI_OP_conf_[read|write]: Read/Write 0xCF8/0xCFC filtered data. (conf_space*.c) Based on which field is probed, we either enable/disable the PCI device, change power state, read VPD, etc. The major goal of this call is to provide a Physical IRQ (PIRQ) to the guest. The PIRQ is Xen hypervisor global IRQ value irrespective of the IRQ is tied in to the IO-APIC, or is a vector. For GSI type interrupts, the PIRQ==GSI holds. For MSI/MSI-X the PIRQ value != Linux IRQ number (thought PIRQ==vector). Please note, that with Xen, all interrupts (except those level shared ones) are injected directly to the guest - there is no host interaction. XEN_PCI_OP_[enable|disable]_msi[|x] (pciback_ops.c) Enables/disables the MSI/MSI-X capability of the device. These operations setup the MSI/MSI-X vectors for the guest and pass them to the frontend. When the device is activated, the interrupts are directly injected in the guest without involving the host. XEN_PCI_OP_aer_[detected|resume|mmio|slotreset]: In case of failure, perform the appropriate AER commands on the guest. Right now that is a cop-out - we just kill the guest. Besides implementing those commands, it can also - hide a PCI device from the host. When booting up, the user can specify xen-pciback.hide=(1:0:0)(BDF..) so that host does not try to use the device. The driver was lifted from linux-2.6.18.hg tree and fixed up so that it could compile under v3.0. Per suggestion from Jesse Barnes moved the driver to drivers/xen/xen-pciback.

2011-07-20kernel: prevent unnecessary rebuilding due to config_data.gzPeter Foley
When IKCONFIG is built-in make oldconfig will cause the kernel to be relinked even if .config didn't change. This happens because of a config_data.gz dependency on .config. This patch changes the if_changed to a filechk so that config_data.h is only rebuilt when the contents have actually changed.

2011-07-19EHCI: fix direction handling for interrupt data togglesAlan Stern
This patch (as1480) fixes a rather obscure bug in ehci-hcd. The qh_update() routine needs to know the number and direction of the endpoint corresponding to its QH argument. The number can be taken directly from the QH data structure, but the direction isn't stored there. The direction is taken instead from the first qTD linked to the QH. However, it turns out that for interrupt transfers, qh_update() gets called before the qTDs are linked to the QH. As a result, qh_update() computes a bogus direction value, which messes up the endpoint toggle handling. Under the right combination of circumstances this causes usb_reset_endpoint() not to work correctly, which causes packets to be dropped and communications to fail. Now, it's silly for the QH structure not to have direct access to all the descriptor information for the corresponding endpoint. Ultimately it may get a pointer to the usb_host_endpoint structure; for now, adding a copy of the direction flag solves the immediate problem. This allows the Spyder2 color-calibration system (a low-speed USB device that sends all its interrupt data packets with the toggle set to 0 and hance requires constant use of usb_reset_endpoint) to work when connected through a high-speed hub. Thanks to Graeme Gill for supplying the hardware that allowed me to track down this bug.

2011-07-19ceph: fix file mode calculationSage Weil
open(2) must always include one of O_RDONLY, O_WRONLY, or O_RDWR. No need for any O_APPEND special case. Passing O_WRONLY|O_RDWR is undefined according to the man page, but the Linux VFS interprets this as O_RDWR, so we'll do the same. This fixes open(2) with flags O_RDWR|O_APPEND, which was incorrectly being translated to readonly. Reported-by: Fyodor Ustinov <ufm@ufm.su> Signed-off-by: Sage Weil <sage@newdream.net>

2011-07-19ASoC: Mark cache as dirty when suspendingMark Brown
Since quite a few drivers are not managing to flag the cache as needing to be resynced after suspend and it's a reasonable thing to do flag the cache as needing sync automatically when suspending. The expectation is that systems will mainly only keep the CODEC powered when doing audio through the CODEC so we won't actually suspend the device anyway; drivers which want to can override this behaviour when they resume.
