| | | | | | | | | | sdp4430_spi_board_info.irq was initialized to ETH_KS8851_IRQ and in omap_4430sdp_init() overwritten with gpio_to_irq(ETH_KS8851_IRQ) before sdp4430_spi_board_info was registered. This is a bit confusing, so better don't initialize .irq and document that it is set later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It used to be that minors where 8 bit. But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.

Adding empty body defitions in the !CONFIG_PCI case, which is what this patch does, breaks the parisc compile because the functions become doubly defined. It took us a while to spot this, because we don't actually build !CONFIG_PCI very often (only if someone is brave enough to test the snake/asp machines). Since the note in the commit log says this is to fix a CONFIG_GENERIC_IOMAP issue (which it does because CONFIG_GENERIC_IOMAP supplies pci_iounmap only if CONFIG_PCI is set), there should actually have been a condition upon this. This should make sure no other architecture's !CONFIG_PCI compile breaks in the same way as parisc. The fix had to be updated to take account of the GENERIC_PCI_IOMAP separation.

This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.

Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner.

It's necessary to enable the optional clock DSS_FCLK before we enable the module using the MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register. This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led to DSS clock domain not getting out of idle when pm_runtime_get_sync() was called for hdmi's platform device. Since the clock domain failed to change it's state to active, the hwmod code disables any clocks it had enabled before for this hwmod. This led to the clock 'dss_48mhz_clk' gettind disabled. When hdmi's runtime_resume() op is called, the call to dss_runtime_get() correctly enables the DSS clock domain this time. However, the clock 'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was disabled previously, the driver fails when it tries to enable HDMI's PHY. Fix this for now by ensuring that dss_runtime_get() is called before we call pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would be to modify the DSS related hwmod's mainclks, and also some changes in how opt clocks are handled in the DSS driver. This fixes the issue of HDMI not working when it's the default display. The issue is not seen if any other display is already enabled as the first display would have correctly enabled the DSS clockdomain.

It'd be handy if the parser provides the mute mixers in such a case. This patch adds an extension amp-cap bit (which is used only in the driver) to represent the min volume = mute state. Also modified the amp cache code to support the fake mute feature when this bit is set but the real mute bit is unset. In addition, conexant cx5051 parser uses this new feature to implement the missing mute controls.

And I have a version of it that does things at the full width of the CPU wordsize at a time, but that means that we *really* want to split it up into a separate helper function. So this re-organizes the code a bit and splits the hashing part into a helper function called "hash_name()". It returns the length of the pathname component, while at the same time computing and writing the hash to the appropriate location. The code generation is slightly changed by this patch, but generally for the better - and the added abstraction actually makes the code easier to read too. And the new interface is well suited for replacing just the "hash_name()" function with alternative implementations. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

There aren't any performance-critical users, so inlining it is silly. But it wouldn't matter if it wasn't for the fact that the word-at-a-time dentry name patches want to conditionally replace the function, and uninlining it sets the stage for that. So again, this is a preparatory patch that doesn't change any semantics, and only prepares for a much cleaner and testable word-at-a-time dentry name accessor patch.

That is, upon CPU offline, that CPU is removed from all cpusets. However when it comes back online, it is put back only to the root cpuset. This gives rise to a significant problem during suspend/resume. During suspend, we offline all non-boot cpus and during resume we online them back. Which means, after a resume, all cpusets (except the root cpuset) will be restricted to just one single CPU (the boot cpu). But the whole point of suspend/resume is to restore the system to a state which is as close as possible to how it was before suspend. So to fix this, don't touch cpusets during suspend/resume. That is, modify the cpuset-related CPU hotplug callback to just ignore CPU hotplug when it is initiated as part of the suspend/resume sequence.
