| | * mmc: warn about voltage mismatchesDavid Brownell2008-12-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of a silent failure mode when the MMC/SD host doesn't support the voltages needed to operate a given card, by adding a warning. A 3.3V host and a 3.0V card, for example, no longer need to mysteriously just not work at all. This isn't the best diagnostic; ideally it would also tell what voltage the card and host support (and not just by dumping the bitmasks).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unit of the cputime accouting values that are stored per process is currently a microsecond. The CPU timer has a maximum granularity of 2**-12 microseconds. There is no benefit in storing the per process values in the lesser precision and there is the disadvantage that the backend has to do the rounding to microseconds. The better solution is to use the maximum granularity of the CPU timer as cputime unit. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
| * | | [PATCH] idle cputime accountingMartin Schwidefsky2008-12-31

This is plain wrong, the architectures that support VIRT_CPU_ACCOUNTING=y can do better: distinguish between the time spent doing nothing and the time spent by idle doing work. The first is accounted with account_idle_time and the second with account_system_time. The architectures that use the account_xxx_time interface directly and not the account_xxx_ticks interface now need to do the check for the idle process in their arch code. In particular to improve the system vs true idle time accounting the arch code needs to measure the true idle time instead of just testing for the idle process. To improve the tick based accounting as well we would need an architecture primitive that can tell us if the pt_regs of the interrupted context points to the magic instruction that halts the cpu. In addition idle time is no more added to the stime of the idle process. This field now contains the system time of the idle process as it should be. On systems without VIRT_CPU_ACCOUNTING this will always be zero as every tick that occurs while idle is running will be accounted as idle time. This patch contains the necessary common code changes to be able to distinguish idle system time and true idle time. The architectures with support for VIRT_CPU_ACCOUNTING need some changes to exploit this. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

On s390 the calls to account_user_time_scaled and account_system_time_scaled never have been added. In addition system time that is accounted as guest time to the user time of a process is accounted to the scaled system time instead of the scaled user time. To fix the bugs and to prevent future forgetfulness this patch merges account_system_time_scaled into account_system_time and account_user_time_scaled into account_user_time.

* | | Make %p print '(null)' for NULL pointersLinus Torvalds2009-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, when we only ever printed out the pointer value itself, a NULL pointer would never cause issues and might as well be printed out as just its numeric value. However, with the extended %p formats, especially %pR, we might validly want to print out resources for debugging. And sometimes they don't even exist, and the resource pointer is just NULL. Print it out as such, rather than oopsing. This is a more generic version of a patch done by Trent Piepho (catching all %p cases rather than just %pR, and using "(null)" instead of "[NULL]" to match glibc).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | UBI now has (fake for now, though) synchronization call - use it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | | UBIFS: always commit in sync_fsArtem Bityutskiy2008-12-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Always run commit in sync_fs, because even if the journal seems to be almost empty, there may be a deletion which removes a large file, which affects the index greatly. And because we want better free space predictions after 'sync_fs()', we have to commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | | UBIFS: fix file-system synchronizationArtem Bityutskiy2008-12-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Argh. The ->sync_fs call is called _before_ all inodes are flushed. This means we first sync write buffers and commit, then all inodes are synced, and we end up with unflushed write buffers! Fix this by forcing synching all indoes from 'ubifs_sync_fs()'.
