* mmc: deprecate mmc bus topologyPierre Ossman2007-05-01
| | | | | | | | | | | | | | | | | | The classic MMC bus was defined as multi card bus system, which is reflected in the design in the MMC layer. When SD showed up, the bus topology was abandoned and a star topology (one card per host) was mandated. MMC version 4 has followed this, officially deprecating the bus topology. As we do not have any known users of the bus topology we can remove support for it. This will simplify the code and rectify some incorrect assumptions in the newer additions.

* mmc: Flush pending detects on host removalPierre Ossman2007-05-01
| | | | | | | | | Make sure we kill of any pending detection runs when the host is removed instead of when it is freed. Also add some debugging to make sure the driver doesn't queue up more detection after it has removed the host. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* tifm_sd: implement software scatter-gatherAlex Dubov2007-05-01
| | | | | | | | | | | It was found that delays associated with issue and completion of the commands severely limit performance of the new, fast SD cards. To alleviate this issue scatter-gather emulation in software is implemented for both dma and pio transfer modes. Non-block aligned and high memory sg entries are accounted for.

* power management: force pm_ops.valid callback to be assignedJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | This patch changes the docs and behaviour from "all states valid" to "no states valid" if no .valid callback is assigned. Users of pm_ops that only need mem sleep can assign pm_valid_only_mem without any overhead, others will require more elaborate callbacks. Now that all users of pm_ops have a .valid callback this is a safe thing to do and prevents things from getting messy again as they were before.

* power management: implement pm_ops.valid for everybodyJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | | | | | Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

* rework pm_ops pm_disk_mode, kill misuseJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

* Extend print_symbol capabilityRobert Peterson2007-04-30
| | | | | | | | | | | | | | | | | | | | | Today's print_symbol function dumps a kernel symbol with printk. This patch extends the functionality of kallsyms.c so that the symbol lookup function may be used without the printk. This is useful for modules that want to dump symbols elsewhere, for example, to debugfs. I intend to use the new function call in the GFS2 file system (which will be a separate patch).

However, currently we have issue to use the same bundle created for the first time with all flows covered by the case. It is useful for the bundle to have the upper layer information to be restructured correctly if it does not match with the flow. 1. Bundle was created by two policies Selector from another policy is added to xfrm_dst. If the flow does not match the selector, it goes to slow path to restructure new bundle by single policy. 2. Bundle was created by one policy Flow cache is added to xfrm_dst as originated one. If the flow does not match the cache, it goes to slow path to try searching another policy.

Eventually these bugs trigger traps in the tcp_clean_rtx_queue with SACK but it's much more informative to do this here. Non-SACK TCP, however, could get more than packets_out duplicate ACKs which each increment sacked_out, so it makes sense to do this kind of limitting for non-SACK TCP but not for SACK enabled one. Perhaps the author had the opposite in mind but did the logic accidently wrong way around? Anyway, the sacked_out incrementer code for non-SACK already deals this issue before calling sync_left_out so this trapping can be done unconditionally.

To do that queue the path pending interrupts to a separate list and move the path cleanup out of iucv_path_sever to iucv_path_connect and iucv_path_pending. This creates a new requirement for iucv_path_connect: it may not be called from tasklet context anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check_legacy_ioport makes only sense on PREP, CHRP and pSeries. They may have an isa node with PS/2, parport, floppy and serial ports. Remove the check_legacy_ioport call from ppc_md, it's not needed anymore. Hardware capabilities come from the device-tree.

| * | | [POWERPC] Prepare for splitting up mmu.h by MMU typeDavid Gibson2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently asm-powerpc/mmu.h has definitions for the 64-bit hash based MMU. If CONFIG_PPC64 is not set, it instead includes asm-ppc/mmu.h which contains a particularly horrible mess of #ifdefs giving the definitions for all the various 32-bit MMUs. It would be nice to have the low level definitions for each MMU type neatly in their own separate files. It would also be good to wean arch/powerpc off dependence on the old asm-ppc/mmu.h. This patch makes a start on such a cleanup by moving the definitions for the 64-bit hash MMU to their own file, asm-powerpc/mmu_hash64.h. Definitions for the other MMUs still all come from asm-ppc/mmu.h, however each MMU type can now be one-by-one moved over to their own file, in the process cleaning them up stripping them of cruft no longer necessary in arch/powerpc.
