2009-02-09USB: fsl_qe_udc: Fix stalled TX requests bugAnton Vorontsov
While disabling an endpoint the driver nuking any pending requests, thus completing them with -ESHUTDOWN status. But the driver doesn't clear the tx_req, which means that a next TX request (after ep_enable), might get stalled, since the driver won't queue the new reqests. This patch fixes a bug I'm observing with ethernet gadget while playing with ifconfig usb0 up/down (the up/down sequence disables and enables `in' and `out' endpoints).

2009-02-09USB: fsl_qe_udc: Fix muram corruption by disabled endpointsAnton Vorontsov
Before freeing an endpoint's muram memory, we should stop all activity of the endpoint, otherwise the QE UDC controller might do nasty things with the muram memory that isn't belong to that endpoint anymore. The qe_ep_reset() effectively flushes the hardware fifos, finishes all late transaction and thus prevents the corruption.

2009-02-09USB: fsl_qe_udc: Fix disconnects reporting during bus resetAnton Vorontsov
Freescale QE UDC controllers can't report the "port change" states, so the only way to handle disconnects is to process bus reset interrupts. The bus reset can take some time, that is, few irqs. Gadgets may print the disconnection events, and this causes few repetitive messages in the kernel log. This patch fixes the issue by using the usb_state machine, if the usb controller has been already reset, just quit the reset irq early.

2009-02-09USB: fsl_qe_udc: Fix QE USB controller initializationAnton Vorontsov
qe_udc_reg_init() leaves the USB controller enabled before muram memory initialized. Sometimes the uninitialized muram memory confuses the controller, and it start sending the busy interrupts. Fix this by disabling the controller, it will be enabled later by the gadget driver, at bind time.

2009-02-09USB: fsl_qe_udc: Fix oops on QE UDC probe failureAnton Vorontsov
In case of probing errors the driver kfrees the udc_controller, but it doesn't set the pointer to NULL. When usb_gadget_register_driver is called, it checks for udc_controller != NULL, the check passes and the driver accesses nonexistent memory. Fix this by setting udc_controller to NULL in case of errors. While at it, also implement irq_of_parse_and_map()'s failure and cleanup cases.

2009-02-08radeonfb: Fix resume from D3Cold on some platformsBenjamin Herrenschmidt
For historical reason, this driver used its own saving/restoring of the PCI config space, and used the state of it on resume as an indication as to whether it needed to re-POST the chip or not. This methods breaks with the later core changes since the core will have restored things for us. This patch fixes it by removing that custom code, using standard core methods to save/restore state, and testing for the need to re-POST by comparing the content of a few key PLL registers.

This fixes aty128fb to properly save the PCI config space -before- it potentially switches the PM state of the chip. This avoids a warning with the new PM core and is the right thing to do anyway. I also replaced the hand-coded switch to D2 with a call to the genericc pci_set_power_state() and removed the code that switches it back to D0 since the generic code is doing that for us nowadays.

This fixes atyfb to properly save the PCI config space -before- it potentially switches the PM state of the chip. This avoids a warning with the new PM core and is the right thing to do anyway. I also slightly cleaned up the code that checks whether we are running on a PowerMac to do a runtime check instead of a compile check only, and replaced a deprecated number with the proper symbolic constant.

2009-02-08drm/i915: select framebuffer support automaticallyIngo Molnar
Migration helper. The i915 driver recently added a 'depends on FB' rule to its Kconfig entry - which silently turns off DRM_I915 if someone has a working config but no CONFIG_FB selected, and upgrades to the latest upstream kernel. Norbert Preining reported this problem: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12599 Subject : dri /dev node disappeared with 2.6.29-rc1 So change it to "select FB", which auto-selects framebuffer support. This way the driver keeps working, regardless of whether FB was enabled before or not. Kconfig select's of interactive options can be problematic to dependencies and can cause build breakages - but in this case it's safe because it's a leaf entry with no dependencies of its own. ( There is some minor circular dependency fallout as FB_I810 and FB_INTEL also used 'depends on FB' constructs - update those to "select FB" too. ) Reported-by: Norbert Preining <preining@logic.at> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Dave Airlie <airlied@linux.ie>
2009-02-08drm/i915: add get_vblank_counter function for GM45Jesse Barnes
As discussed in the long thread about vblank related timeouts, it turns out GM45 has different frame count registers than previous chips. This patch adds support for them, which prevents us from waiting on really stale sequence values in drm_wait_vblank (which rather than returning immediately ends up timing out or getting interrupted).

2009-02-08drm/i915: capture last_vblank count at IRQ uninstall time tooJesse Barnes
In dc1336ff4fe08ae7cfe8301bfd7f0b2cfd31d20a (set vblank enable flag correctly across IRQ uninstall), we made sure drivers that uninstall their interrupt handler set the vblank enabled flag correctly, so that when interrupts are re-enabled, vblank interrupts & counts work as expected. However I missed the last_vblank field: it needs to be updated as well, otherwise, at the next drm_update_vblank_count we'll end up comparing a current count to a stale one (the last one captured by the disable function), which may trigger the wraparound handling, leading to a jumpy counter and hangs in drm_wait_vblank. The jumpy counter can prevent the DRM_WAIT_ON from returning success if the difference between the current count and the requested count is greater than 2^23, leading to timeouts or hangs, if the ioctl is restarted in a loop (as is the case in libdrm < 2.4.4).

eeepc-laptop init I got the following oops while changing the backlight brightness during startup. When it happens, it prevents use of the hotkeys, Fn-Fx, and the lid button. It's a clear use-before-init, as I verified by testing with an appropriately-placed "else printk".

2009-02-07ACPICA: Fix table entry truncation calculationMyron Stowe
During early boot, ACPI RSDT/XSDT table entries are gathered into the 'initial_tables[]' array. This array is currently statically defined (see ./drivers/acpi/tables.c). When there are more table entries than can be held in the 'initial_tables[]' array, the message "Truncating N table entries!" is output. As currently implemented, this message will always erroneously calculate N as 0. This patch fixes the calculation that determines how many table entries will be missing (truncated). This modification may be used under either the GPL or the BSD-style license used for Intel ACPI CA code.
