[Linux-stable-mirror] Patch "gpio: altera: Use handle_level_irq when configured as a level_high" has been added to the 4.9-stable tree

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Tue Dec 12 13:26:17 CET 2017 From: Phil Reid <preid(a)electromag.com.au> Date: Mon, 20 Feb 2017 09:41:45 +0800 Subject: gpio: altera: Use handle_level_irq when configured as a level_high From: Phil Reid <preid(a)electromag.com.au> [ Upstream commit f759921cfbf4847319d197a6ed7c9534d593f8bc ] When a threaded irq handler is chained attached to one of the gpio pins when configure for level irq the altera_gpio_irq_leveL_high_handler does not mask the interrupt while being handled by the chained irq. This resulting in the threaded irq not getting enough cycles to complete quickly enough before the irq was disabled as faulty. handle_level_irq should be used in this situation instead of handle_simple_irq. In gpiochip_irqchip_add set default handler to handle_bad_irq as per Documentation/gpio/driver.txt. Then set the correct handler in the set_type callback.

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Tue Dec 12 13:26:17 CET 2017 From: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Tue, 14 Nov 2017 20:38:07 +0900 Subject: coccinelle: fix parallel build with CHECK=scripts/coccicheck From: Masahiro Yamada <yamada.masahiro(a)socionext.com> [ Upstream commit d7059ca0147adcd495f3c5b41f260e1ac55bb679 ] The command "make -j8 C=1 CHECK=scripts/coccicheck" produces lots of "coccicheck failed" error messages. Julia Lawall explained the Coccinelle behavior as follows: "The problem on the Coccinelle side is that it uses a subdirectory with the name of the semantic patch to store standard output and standard error for the different threads. I didn't want to use a name with the pid, so that one could easily find this information while Coccinelle is running. Normally the subdirectory is cleaned up when Coccinelle completes, so there is only one of them at a time. Maybe it is best to just add the pid. There is the risk that these subdirectories will accumulate if Coccinelle crashes in a way such that they don't get cleaned up, but Coccinelle could print a warning if it detects this case, rather than failing." When scripts/coccicheck is used as CHECK tool and -j option is given to Make, the whole of build process runs in parallel. So, multiple processes try to get access to the same subdirectory. I notice spatch creates the subdirectory only when it runs in parallel (i.e. --jobs <N> is given and <N> is greater than 1). Setting NPROC=1 is a reasonable solution; spatch does not create the subdirectory. Besides, ONLINE=1 mode takes a single file input for each spatch invocation, so there is no reason to parallelize it in the first place.

As configurable disables/enables are added to the architecture (controlled by RES1/RES0 bits respectively), with associated synchronous exceptions, it may be possible for a guest to trigger exceptions with classes that we don't recognise. While we can't service these exceptions in a manner useful to the guest, we can avoid bringing down the host. Per ARM DDI 0487A.k_iss10775, page D7-1937, EC values within the range 0x00 - 0x2c are reserved for future use with synchronous exceptions, and EC values within the range 0x2d - 0x3f may be used for either synchronous or asynchronous exceptions. The patch makes KVM handle any unknown EC by injecting an UNDEFINED exception into the guest, with a corresponding (ratelimited) warning in the host dmesg. We could later improve on this with with a new (opt-in) exit to the host userspace.

The commit referenced above exposes this problem. To fix the problem, use of_get_child_by_name() instead of of_find_node_by_name(); of_get_child_by_name() does not drop the reference count of passed device nodes. While semantically different, we only look for immediate children of the passed device node, so of_get_child_by_name() is a more appropriate function to use anyway. Release the reference to the device node obtained with of_get_child_by_name() after it is no longer needed to avoid another device node leak. While at it, clean up the code and change the return type of omap3xxx_hwmod_is_hs_ip_block_usable() to bool to match its use and the return type of of_device_is_available().
