2007-10-18unify DMA_..BIT_MASK definitions: v3.1Borislav Petkov
Remove redundant DMA_..BIT_MASK definitions across two drivers. The computation of the majority of the bitmasks is done by the compiler. The initial split of the patch touching each a different file got removed due to possible git bisect breakage.

2007-10-18Hibernation: Check if ACPI is enabled during restore in the right placeRafael J. Wysocki
The following scenario leads to total confusion of the platform firmware on some boxes (eg. HPC nx6325): * Hibernate with ACPI enabled * Resume passing "acpi=off" to the boot kernel To prevent this from happening it's necessary to check if ACPI is enabled (and enable it if that's not the case) _right_ _after_ control has been transfered from the boot kernel to the image kernel, before device_power_up() is called (ie. with interrupts disabled).  Enabling ACPI after calling device_power_up() turns out to be insufficient. For this reason, introduce new hibernation callback ->leave() that will be executed before device_power_up() by the restored image kernel.  To make it work, it also is necessary to move swsusp_suspend() from swsusp.c to disk.c (it's name is changed to "create_image", which is more up to the point).

2007-10-18serial: turn serial console suspend a boot rather than compile time optionAndres Salomon
Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop the serial console from being suspended when the rest of the machine goes to sleep. This is incredibly useful for debugging power management-related things; however, having it as a compile-time option has proved to be incredibly inconvenient for us (OLPC). There are plenty of times that we want serial console to not suspend, but for the most part we'd like serial console to be suspended. This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel boot parameter (no_console_suspend). By default, the serial console will be suspended along with the rest of the system; by passing 'no_console_suspend' to the kernel during boot, serial console will remain alive during suspend. For now, this is pretty serial console specific; further fixes could be applied to make this work for things like netconsole. Signed-off-by: Andres Salomon <dilinger@debian.org> Acked-by: "Rafael J.

2007-10-18PM: Rework struct hibernation_opsRafael J. Wysocki
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).

2007-10-18PM: Rework struct platform_suspend_opsRafael J. Wysocki
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.

2007-10-18PM: Rename struct pm_ops and related thingsRafael J. Wysocki
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.

2007-10-18PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki
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> .

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.

2007-10-17PNP: don't fail device init if no DMA channel availableJan Beulich
Most drivers for devices supporting ISA DMA can operate without DMA as well (falling back zo PIO). 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.

2007-10-17PNP: make pnpacpi_suspend handle errorsRafael J. Wysocki
pnpacpi_suspend() doesn't check the result returned by acpi_pm_device_sleep_state() before passing it to acpi_bus_set_power(), which may not be desirable.  Make it select the target power state of the device using its second argument if acpi_pm_device_sleep_state() fails.

2007-10-17floppy: remove register keyword use from floppy driverJesper Juhl
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).

2007-10-17floppy: remove dead/commented out code from floppy driverJesper Juhl
A good initial step for a cleanup seems to me to be getting rid of old dead code. This stuff is either commented out or inside '#if 0' so it is not currently in use at all, let's just get rid of it once and for all. That's a few lines less to deal with.

2007-10-17floppy: do a very minimal style cleanup of the floppy driverJesper Juhl
Yes, some of this will likely be replaced in later patches, but I do not see anyone else coming out of the woodwork with any patches for this driver, so I'll ignore comments about churn. I want to get this driver cleaned up, and if I'm going to do so I want to start with this basic style cleanup to reduce the reading pain a bit.

2007-10-17md: make sure read errors are auto-corrected during a 'check' resync in raid1NeilBrown
Whenever a read error is found, we should attempt to overwrite with correct data to 'fix' it. However when do a 'check' pass (which compares data blocks that are successfully read, but doesn't normally overwrite) we don't do that. We should.

2007-10-17md: expose the degraded status of an assembled array through sysfsIustin Pop
The 'degraded' attribute is useful to quickly determine if the array is degraded, instead of parsing 'mdadm -D' output or relying on the other techniques (number of working devices against number of defined devices, etc.). The md code already keeps track of this attribute, so it's useful to export it.

2007-10-17md: 'sync_action' in sysfs returns wrong value for readonly arraysNeilBrown
When an array is started read-only, MD_RECOVERY_NEEDED can be set but no recovery will be running. This causes 'sync_action' to report the wrong value. We could remove the test for MD_RECOVERY_NEEDED, but doing so would leave a small gap after requesting a sync action, where 'sync_action' would still report the old value. So make sure that for a read-only array, 'sync_action' always returns 'idle'.

2007-10-17md: software Raid autodetect dev list not arrayMichael J. Evans
In current release kernels the md module (Software RAID) uses a static array (dev_t[128]) to store partition/device info temporarily for autostart. I discovered this (and that the devices are added as disks/partitions are discovered at boot) while I was debugging why only one of my MD arrays would come up whole, while all the others were short a disk. I eventually discovered that it was enumerating through all of 9 of my 11 hds (2 had only 4 partitions apiece) while the other 9 have 15 partitions (I wanted 64 per drive...). The last partition of the 8th drive in my 9 drive raid 5 sets wasn't added, thus making the final md array short both a parity and data disk, and it was started later, elsewhere. This patch replaces that static array with a list. [akpm@linux-foundation.org: removed unused var] Signed-off-by: Michael J.
