2010-07-29GFS2: Simplify gfs2_write_alloc_requiredBob Peterson
Function gfs2_write_alloc_required always returned zero as its return code. Therefore, it doesn't need to return a return code at all. Given that, we can use the return value to return whether or not the dinode needs block allocations rather than passing that value in, which in turn simplifies a bunch of error checking.

2010-07-29GFS2: Wait for journal id on mount if not specified on mount command lineSteven Whitehouse
This patch implements a wait for the journal id in the case that it has not been specified on the command line. This is to allow the future removal of the mount.gfs2 helper. The journal id would instead be directly communicated by gfs_controld to the file system. Here is a comparison of the two systems: Current: 1. mount calls mount.gfs2 2. mount.gfs2 connects to gfs_controld to retrieve the journal id 3. mount.gfs2 adds the journal id to the mount command line and calls the mount system call 4. gfs_controld receives the status of the mount request via a uevent Proposed: 1. mount calls the mount system call (no mount.gfs2 helper) 2. gfs_controld receives a uevent for a gfs2 fs which it doesn't know about already 3. gfs_controld assigns a journal id to it via sysfs 4. the mount system call then completes as normal (sending a uevent according to status) The advantage of the proposed system is that it is completely backward compatible with the current system both at the kernel and at the userland levels. The "first" parameter can also be set the same way, with the restriction that it must be set before the journal id is assigned. In addition, if mount becomes stuck waiting for a reply from gfs_controld which never arrives, then it is killable and will abort the mount gracefully.

2010-07-28x86,kgdb: Fix hw breakpoint regressionJason Wessel
HW breakpoints events stopped working correctly with kgdb as a result of commit: 018cbffe6819f6f8db20a0a3acd9bab9bfd667e4 (Merge commit 'v2.6.33' into perf/core). The regression occurred because the behavior changed for setting NOTIFY_STOP as the return value to the die notifier if the breakpoint was known to the HW breakpoint API. Because kgdb is using the HW breakpoint API to register HW breakpoints slots, it must also now implement the overflow_handler call back else kgdb does not get to see the events from the die notifier. The kgdb_ll_trap function will be changed to be general purpose code which can allow an easy way to implement the hw_breakpoint API overflow call back.

2010-07-28GFS2: Use kmalloc when possible for ->readdir()Steven Whitehouse
If we don't need a huge amount of memory in ->readdir() then we can use kmalloc rather than vmalloc to allocate it. This should cut down on the greater overheads associated with vmalloc for smaller directories. We may be able to eliminate vmalloc entirely at some stage, but this is easy to do right away. Also using GFP_NOFS to avoid any issues wrt to deleting inodes while under a glock, and suggestion from Linus to factor out the alloc/dealloc. I've given this a test with a variety of different sized directories and it seems to work ok.

Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> In TPS6507x, depending on the status of DEFDCDC{2,3} pin either DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or programmed to change the output voltage. The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.

2010-07-27[S390] etr: fix clock synchronization raceMartin Schwidefsky
The etr events switch-to-local and sync-check disable the synchronous clock and schedule a work queue that tries to get the clock back into sync. If another switch-to-local or sync-check event occurs while the work queue function etr_work_fn still runs the eacr.es bit and the clock_sync_word can become inconsistent because check_sync_clock only uses the clock_sync_word to determine if the clock is in sync or not. The second pass of the etr_work_fn will reset the eacr.es bit but will leave the clock_sync_word intact. Fix this race by moving the reset of the eacr.es bit into the switch-to-local and sync-check functions and by checking the eacr.es bit as well to decide if the clock needs to be synced.
