* PM: Rename hibernation_ops to platform_hibernation_opsRafael J. Wysocki2007-10-18
| | | | | | | | | | | | Rename 'struct hibernation_ops' to 'struct platform_hibernation_ops' in analogy with 'struct platform_suspend_ops'. Signed-off-by: Rafael J.

* PM: Rework struct hibernation_opsRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | | During hibernation we also need to tell the ACPI core that we're going to put the system into the S4 sleep state. For this reason, an additional method in 'struct hibernation_ops' is needed, playing the role of set_target() in 'struct platform_suspend_operations'. Moreover, the role of the .prepare() method is now different, so it's better to introduce another method, that in general may be different from .prepare(), that will be used to prepare the platform for creating the hibernation image (.prepare() is used anyway to notify the platform that we're going to enter the low power state after the image has been saved).

* PM: Rework struct platform_suspend_opsRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | | There is no reason why the .prepare() and .finish() methods in 'struct platform_suspend_ops' should take any arguments, since architectures don't use these methods' argument in any practically meaningful way (ie. either the target system sleep state is conveyed to the platform by .set_target(), or there is only one suspend state supported and it is indicated to the PM core by .valid(), or .prepare() and .finish() aren't defined at all).  There also is no reason why .finish() should return any result.

* PM: Rename struct pm_ops and related thingsRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

* PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | | | | | | | Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

* i4l: Fix random hard freeze with AVM c4 cardKarsten Keil2007-10-18
| | | | | | | | | | | | | | | | | | | | | The patch - Includes the call to capilib_data_b3_req in the spinlock. This routine in turn calls the offending mq_enqueue routine that triggered the freeze if not locked. This should also fix other indicators of incosistent capilib_msgidqueue list, that trigger messages like: Oct 5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue that we saw several times a day (usually several in a row). - Fixes all occurrences of c4_dispatch_tx to be called with active spinlock, there were some instances where no lock was active. Mostly these are in very infrequently called routines, so the additional performance penalty is minimal.

This patch removes the set_lazy_mode operation, and adds "enter" and "leave" lazy mode operations on mmu_ops and cpu_ops. All the logic associated with enter and leaving lazy states is now in common code (basically BUG_ONs to make sure that no mode is current when entering a lazy mode, and make sure that the mode is current when leaving). Also, flush is handled in a common way, by simply leaving and re-entering the lazy mode. The result is that the Xen, lguest and VMI lazy mode implementations are much simpler.

Some of these ops will be general to all x86, and some will be i386/x86-64 specific. This makes it easier to share common stuff while allowing separate implementations where needed. 2. At the moment we must export all of paravirt_ops, but modules only need selected parts of it. This allows us to export on a case by case basis (and also choose which export license we want to apply). 3. Functional groupings make things a bit more readable. Struct paravirt_ops is now only used as a template to generate patch-site identifiers, and to extract function pointers for inserting into jmp/calls when patching. It is only instantiated when needed.

Thus it seems inappropriate for PNP to fail device initialization in case none of the possible DMA channels are available. Instead, it should be left to the driver to decide what to do if request_dma() fails. The patch at once adjusts the code to account for the fact that pnp_assign_dma() now doesn't need to report failure anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The floppy drive is slow. These days I see absolutely no good reason why the floppy driver should try to gain a tiny bit of speed by telling gcc to optimize access to some variables via the register keyword. Better to just leave gcc free to do whatever optimizations it deduces to be sane and not hamper it by telling it that some variables in the floppy driver are special and need to be fast (they don't).
