2009-05-29ACPI: sanity check _PSS frequency to prevent cpufreq crashLen Brown
When BIOS SETUP is changed to disable EIST, some BIOS hand the OS an un-initialized _PSS: Name (_PSS, Package (0x06) { Package (0x06) { 0x80000000, // frequency [MHz] 0x80000000, // power [mW] 0x80000000, // latency [us] 0x80000000, // BM latency [us] 0x80000000, // control 0x80000000 // status }, ... These are outrageous values for frequency, power and latency, raising the question where to draw the line between legal and illegal. We tend to survive garbage in the power and latency fields, but we can BUG_ON when garbage is in the frequency field. Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz. So disregard a _PSS with a frequency so large that it can't be represented by cpufreq. https://bugzilla.redhat.com/show_bug.cgi?id=500311 Signed-off-by: Len Brown <len.brown@intel.com>

If you setserial a port which has never been initialised we change the type but don't update the I/O method pointers. The same problem is true if you change the io type of a port - but nobody ever does that so nobody noticed! Remember the old type and when attaching if the type has changed reload the port accessor pointers. We can't do it blindly as some 8250 drivers load custom accessors and we must not stomp those.

Commit 5e68b772e6efd189d6aca76f6872fb75d51ace60 cxgb3: map entire Rx page, feed map+offset to Rx ring. introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR() and related macros as no-ops. Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

2009-05-28i7300_idle: allow testing on i5000-series hardware w/o re-compileLen Brown
Testing the i7300_idle driver on i5000-series hardware required an edit to i7300_idle.h to "#define SUPPORT_I5000 1" and a re-build of both i7300_idle and ioat_dma. Replace that build-time scheme with a load-time module parameter: "7300_idle.forceload=1" to make it easier to test the driver on hardware that while not officially validated, works fine and is much more commonly available. By default (no modparam) the driver will continue to load only on the i7300. Note that ioat_dma runs a copy of i7300_idle's probe routine to know to reserve an IOAT channel for i7300_idle. This change makes ioat_dma do that always on the i5000, just like it does on the i7300. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Andrew Henroid <andrew.d.henroid@intel.com>

2009-05-28usb-serial: fix crash when sub-driver updates firmwareAlan Stern
This patch (as1244) fixes a crash in usb-serial that occurs when a sub-driver returns a positive value from its attach method, indicating that new firmware was loaded and the device will disconnect and reconnect. The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

2009-05-28USB: isp1760: urb_dequeue doesn't always find the urbsWarren Free
The option driver (and presumably others) allocates several URBs when it opens and tries to free them when it closes. The isp1760_urb_dequeue function gets called, but the packet being dequeued is not necessarily at the front of one of the 32 queues. If not, the isp1760_urb_done function doesn't get called for the URB and the process trying to free it hangs forever on a wait_queue. This patch does two things. If the URB being dequeued has others queued behind it, it re-queues them. And it searches the queues looking for the URB being dequeued rather than just looking at the one at the front of the queue.

The 'dev' field of struct acpi_pci_data is having a pointer to struct pci_dev without incrementing the reference counter. Because of this, I got the following kernel oops when I was doing some pci hotplug operations. This patch fixes this bug by replacing wrong hand-made pci_find_slot() with pci_get_slot() in acpi_pci_bind().
