* | ARM: smp: Drop RCU_NONIDLE usage in cpu_die()Stephen Boyd2013-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | Before f7b861b7a6d9 ("arm: Use generic idle loop") ARM would kill the CPU within the rcu idle section. Now that the rcu_idle_enter()/exit() pair have been pushed lower down in the idle loop this is no longer true and so using RCU_NONIDLE here is no longer necessary and also harmful because RCU is not actually idle at this point.

I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

This clears the top 32 bits of the old and new values, resulting in the wrong values being compare-exchanged. Luckily, this only appears to be used for 64-bit sched_clock, which we don't (yet) have on ARM.

This update allowed the interrupt type (edge, level, etc) to be configured via device-tree (as described in the Documentation/devicetree/bindings/gpio/gpio-omap.txt). This broke ethernet support on the OMAP4 SDP board that defines a gpio as the ethernet IRQ because the interrupt type (level, edge, etc) was not getting configured correctly. This board use the ks8851 ethernet chip which has an active low interrupt. Fix this by defining the gpio interrupt as active-low in the device-tree binding. Please note that the OMAP4-VAR-SOM also uses the same ethernet controller and it is expected it will have the same problem. So the same fix is also applied to this board.

For the first, IS_ERR() is sufficient. For the second, tell me what error checking is required in the return value of this function: struct device *soc_device_to_device(struct soc_device *soc_dev) { return &soc_dev->dev; } when you've already determined that the passed soc_dev is a valid pointer. If you read the comments against the prototype: /** * soc_device_to_device - helper function to fetch struct device * @soc: Previously registered SoC device container */ struct device *soc_device_to_device(struct soc_device *soc); if "soc" is valid, it means the "previously registered SoC device container" must have succeeded and that can only happen if the struct device has been registered. Ergo, there will always be a valid struct device pointer for any registered SoC device container. Therefore, if soc_device_register() succeeds, then the return value from soc_device_to_device() will always be valid and no error checking of it is required. Simples. The rule as ever applies here: get to know the APIs your using and don't fumble around in the dark hoping that you'll get this stuff right. Fix it as noted by Russell.

But this function does not use the GPMC device node as the root of the search and instead search across the complete Device Tree. This means that any device node on the DT that is using any of the GPMC child nodes names searched for will be returned even if they are not connected to the GPMC, making the gpmc_probe_xxx_child() function to fail. Fix this by using the GPMC device node as the search root so the search will be restricted to its children.

The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.

The exact cause is not fully understood, but it seems to be related to the probe order. SPI communication to the panel driver (spi1.2) fails unless the touchscreen (spi1.0) has been probed/initialized before. When the omap2-mcspi driver was converted to a platform driver, it resulted in that the devices are probed immediately after the board registers them in the order they are listed in the board file. Fix the issue by moving the touchscreen before the panel in the SPI device list. The patch fixes the following failure: [ 1.260955] acx565akm spi1.2: invalid display ID [ 1.265899] panel-acx565akm display0: acx_panel_probe panel detect error [ 1.273071] omapdss CORE error: driver probe failed: -19 Tested-by: Sebastian Reichel <sre@debian.org> Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: Pali Rohár <pali.rohar@gmail.com> Cc: Joni Lapilainen <joni.lapilainen@gmail.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Felipe Balbi <balbi@ti.com> Cc: stable@vger.kernel.org Signed-off-by: Tony Lindgren <tony@atomide.com>
