* qeth: avoid crash in case of layer mismatch for VSWITCHUrsula Braun2009-01-053-6/+14
| | | | | | | | | | | | | | For z/VM GuestLAN or VSWITCH devices the transport layer is configured in z/VM. The layer2 attribute of a participating Linux device has to match the z/VM definition. In case of a mismatch Linux currently crashes in qeth recovery due to a reference to the not yet existing net_device. Solution: add a check for existence of net_device and add a message pointing to the mismatch of layer definitions in Linux and z/VM.

* qlge: bugfix: Fix shadow register endian issue.Ron Mercer2009-01-052-22/+7
| | | | | | | | | | | | | | | | | | | Shadow registers are consistent memory locations to which the chip echos ring indexes in little endian format. These values need to be endian swapped before referencing. Note: The register pointer declaration uses the volatile modifier which causes warnings in checkpatch. Per Documentation/volatile-considered-harmful.txt: - Pointers to data structures in coherent memory which might be modified by I/O devices can, sometimes, legitimately be volatile. A ring buffer used by a network adapter, where that adapter changes pointers to indicate which descriptors have been processed, is an example of this type of situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC In drivers/net/wireless/zd1211rw/zd_usb.c the code: (endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than USB_TYPE_MASK, then the whole conditional test could be converted to a call to usb_endpoint_is_bulk_in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the QPACE (Chromodynamics Parallel Computing on the Cell Broadband Engine) platform doesn't use a iommu, doesn't have PCI devices and a MPIC much lesser setup and configurations are needed. So far all devices are detected as OF device. A notifier function is used to set the dma_ops for the of_platform bus.

| * powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDEDBenjamin Herrenschmidt2008-12-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we never set _PAGE_COHERENT in the PTEs, we just OR it in in the hash code based on some CPU feature bit. We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

This commit allows users to send ^O to applications by pressing ^O twice in succession. To implement this, this commit introduces a check if ^O is pressed again if the sysrq_pressed variable is already set. In this case, clear sysrq_pressed state and flip the ^O character to the tty. (The old behavior has always set "sysrq_pressed" if ^O has been entered, and it has not flipped the ^O character to the tty.)

Sometimes we want to differentiate holes from real errors -- for example when we want to count all the [syntax correct] specifiers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test to check for a new winsize runs out-of-sync with the underlying tty. After a tty has been released and initialized again, the winsize might differ between the tty and the hp struct. The solution is to simply remove the check and always schedule the resize work.

| * | | of/gpio: Implement of_get_gpio_flags()Anton Vorontsov2008-12-031-7/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new function, of_get_gpio_flags, which is like of_get_gpio(), but accepts a new "flags" argument. This new function will be used by the drivers that need to retrieve additional GPIO information, such as active-low flag. Also, this changes the default ("simple") .xlate routine to warn about bogus (< 2) #gpio-cells usage: the second cell should always be present for GPIO flags.
