commit aba8d056 upstream. In addition to /etc/perfconfig and $HOME/.perfconfig, perf looks for configuration in the file ./config, imitating git which looks at $GIT_DIR/config. If ./config is not a perf configuration file, it fails, or worse, treats it as a configuration file and changes behavior in some unexpected way. "config" is not an unusual name for a file to be lying around and perf does not have a private directory dedicated for its own use, so let's just stop looking for configuration in the cwd. Callers needing context-sensitive configuration can use the PERF_CONFIG environment variable. Requested-by:

commit d5811e87 upstream. Attempting to try and turn off disconnected display hw in the hotput handler lead to more problems than it helped. For now just register an event and only attempt the do something interesting with DP. Other connectors are just too problematic: - Some systems have an HPD pin assigned to LVDS, but it's rarely if ever connected properly and we don't really care about hpd events on LVDS anyway since it's always connected. - The HPD pin is wired up correctly for eDP, but we don't really have to do anything since the events since it's always connected. - Some HPD pins fire more than once when you connect/disconnect - etc. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=39882 Signed-off-by:

commit e22a5398 upstream. The CONFIG_RELOCATABLE code tries to align the unpack destination to the value of 'kernel_alignment' in the setup_hdr. If that's 0, it tries to unpack to address 0, which in fact causes the gunzip code to call 'error("Out of memory while allocating output buffer")'. The bootloader (ie. the lguest Launcher in this case) should be doing setting this field; the normal bzImage is 16M, we can use the same. Reported-by:

commit f982f915 upstream. Commit db64fe02 ("mm: rewrite vmap layer") introduced code that does address calculations under the assumption that VMAP_BLOCK_SIZE is a power of two. However, this might not be true if CONFIG_NR_CPUS is not set to a power of two. Wrong vmap_block index/offset values could lead to memory corruption. However, this has never been observed in practice (or never been diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that checks for inconsistent vmap_block indices. To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=31572 Reported-by:

commit bdc71bc5 upstream. This cleans up error handling for the beacon in case of dma mapping failure. We need to free the skb when dma mapping fails instead of nulling and leaking the pointer, and we should bail out to avoid giving the hardware the bad descriptor. Finally, we need to perform the null check after trying to update the beacon, or else beacons will never be sent after a single mapping failure. Signed-off-by:

commit 29591ed4 upstream. Two issues were preventing module snd-soc-tegra-wm8903.ko from being removed and re-inserted: a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must be freed before snd_soc_unregister_card() is called, because that triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which then fails if any of the GPIOs are in use. To solve this, free all GPIOs first, so the code doesn't care where they come from. b) We need to call snd_soc_jack_free_gpios() to match the call to snd_soc_jack_add_gpios() during initialization. Without this, the call to snd_soc_jack_add_gpios() fails during any subsequent modprobe and initialization, since the GPIO and IRQ are already registered. In turn, this causes the headphone state not to be monitored, so the headphone is assumed not to be plugged in, and the audio path to it is never enabled. Signed-off-by:

commit 7bd89b40 upstream. Commit fccf4e86 "USB: Free bandwidth when usb_disable_device is called" caused a bit of an issue when the xHCI host controller driver is unloaded. It changed the USB core to remove all endpoints when a USB device is disabled. When the driver is unloaded, it will remove the SuperSpeed split root hub, which will disable all devices under that roothub and then halt the host controller. When the second High Speed split roothub is removed, the USB core will attempt to disable the endpoints, which will submit a Configure Endpoint command to a halted host controller. The command will eventually time out, but it makes the xHCI driver unload take *minutes* if there are a couple of USB 1.1/2.0 devices attached. We must halt the host controller when the SuperSpeed roothub is removed, because we can't allow any interrupts from things like port status changes. Make several different functions not submit commands or URBs to the host controller when the host is halted, by adding a check in xhci_check_args(). xhci_check_args() is used by these functions: xhci.c-int xhci_urb_enqueue() xhci.c-int xhci_drop_endpoint() xhci.c-int xhci_add_endpoint() xhci.c-int xhci_check_bandwidth() xhci.c-void xhci_reset_bandwidth() xhci.c-static int xhci_check_streams_endpoint() xhci.c-int xhci_discover_or_reset_device() It's also used by xhci_free_dev(). However, we have to take special care in that case, because we want the device memory to be freed if the host controller is halted. This patch should be backported to the 2.6.39 and 3.0 kernel.

commit 8028837d upstream. The dp83640 buffers receive time stamps from special PHY status frames, matching them to received PTP packets in a work queue. Because the timeout for orphaned time stamps is so long and the buffer is so small, the driver can drop time stamps under moderate PTP traffic. This commit fixes the issue by decreasing the timeout to (at least) one timer tick and increasing the buffer size. Signed-off-by:

commit cbc05660 upstream. After resetting the time, the PPS signals on the FIPER output channels are incorrectly offset from the clock time, as can be readily verified by a looping back the FIPER to the external time stamp input. Despite its name, setting the "Fiper Realignment Disable" bit seems to fix the problem, at least on the P2020. Also, following the example code from the Freescale BSP, it is not really necessary to disable and re-enable the timer in order to reprogram the FIPER. (The documentation is rather unclear on this point. It seems that writing to the alarm register also disables the FIPER.) Signed-off-by:

OF got corrupted with a device tree string. Looking at make_room and alloc_up, we claim the first chunk (1 MB) but we never claim any more. mem_end is always set to alloc_top which is the top of our available address space, guaranteeing we will never call alloc_up and claim more memory. Also alloc_up wasn't setting alloc_bottom to the bottom of the available address space. This doesn't help the box to boot, but we at least fail with an obvious error.
