| | | | | | | | | | | | | The RTT-as-RTC driver will search for the user-specified RTT peripheral via ID number (0 .. 1).

* ACPI: fix Medion _PRT quirk (use "ISA_", not "ISA")Bjorn Helgaas2008-03-25
| | | | | | | | | | | | | | | | | This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The BIOS reports the interrupt routing incorrectly. I recently added a quirk to work around this, and this patch fixes a typo in the quirk. We pad every ACPI pathname component to four characters, so ".ISA." will never match anything. We need ".ISA_." instead. Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de> for patiently testing this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an I2C interrupt happens between disabling interface clock and functional clock, the interrupt handler will produce an external abort on non-linefetch error when trying to access driver registers while interface clock is disabled. This patch fixes the problem by saving and disabling i2c-omap interrupt before turning off the clocks. Also disable functional clock before the interface clock as suggested by Paul Walmsley. Patch also renames enable/disable_clocks functions to unidle/idle functions. Note that the driver is currently not taking advantage of the idle interrupts. To use the idle interrupts, driver would have to enable interface clock based on the idle interrupt and dev->idle flag. This patch has been tested in linux-omap tree with various omaps.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vmx hardware state restore restores the tss selector and base address, but not its length. Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Somebody had put struct nameidata in stack frame of link_path_walk(). Unfortunately, there are certain realities to deal with: * It's in the middle of recursion. Depth is equal to the nesting depth of symlinks, i.e. up to 8. * struct namiedata is, even if one discards the intent junk, at least 12 pointers + 5 ints. * moreover, adding a stack frame is not free in that situation. * there are fs methods called on top of that, and they also have stack footprint. * kernel stack is not infinite. The thing is, even if one chooses to deal with -ESTALE that way (and it's one hell of an overkill), the only thing that needs to be preserved is vfsmount + dentry, not the entire struct nameidata.

It was really only passed around due to the f_op->readdir() and a_ops->{prepare,commit}_write prototypes requiring it. reiserfs_prepare_write() and reiserfs_commit_write() don't actually use the struct file passed to it, and the xattr code uses a private version of reiserfs_readdir() to enumerate the xattr directories.

A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235. So this patch only applies to chips that seem to be incarnations of the (discrete) vt6212. Signed-off-by: Rene Herman <rene.herman@gmail.com> Tested-by: Lev A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Motorola ROKR Z6 cellphone has bugs in its USB, so it is impossible to use it as mass storage. Patch describes new "unusual" USB device for it with FIX_INQUIRY and FIX_CAPACITY flags and new BULK_IGNORE_TAG flag. Last flag relaxes check for equality of bcs->Tag and us->tag in usb_stor_Bulk_transport routine.
