2011-01-05[S390] time: let local_tick_enable/disable() reprogram the clock comparatorHeiko Carstens
Let local_tick_enable/disable() reprogram the clock comparator so the function names make semantically more sense. Also that way the functions are more symmetric since normally each local_tick_enable() call usually would have a subsequent call to set_clock_comparator() anyway.

2011-01-05[S390] time: move local_tick_enable()/disable() to timex.hHeiko Carstens
Move the two functions to timex.h where they make more sense than in hardirq.h. No functional change. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2010-05-17[S390] s390_hypfs: Add new attributesMichael Holzheu
In order to access the data of the hypfs diagnose calls from user space also in binary form, this patch adds two new attributes in debugfs: * z/VM: s390_hypfs/d2fc_bin * LPAR: s390_hypfs/d204_bin Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2010-02-26[S390] use inline assembly contraints available with gcc 3.3.3Martin Schwidefsky
Drop support to compile the kernel with gcc versions older than 3.3.3. This allows us to use the "Q" inline assembly contraint on some more inline assemblies without duplicating a lot of complex code (e.g. __xchg and __cmpxchg). The distinction for older gcc versions can be removed which saves a few lines and simplifies the code.

2009-09-11[S390] introduce get_clock_monotonicHeiko Carstens
Introduce get_clock_monotonic() function which can be used to get a (fast) timestamp. Resolution is the same as for get_clock(). The only difference is that the timestamps are monotonic and don't jump backward or forward.

2009-09-05[SCSI] zfcp: Remove duplicated code for debug timestampsChristof Schmitt
The timestamp calculation used for s390dbf output is the same in a private zfcp function and in debug.c. Replace both with a common inline function.

2009-04-14[S390] add read_persistent_clockMartin Schwidefsky
Add a read_persistent_clock function that does not just return 0. Since timekeeping_init calls the function before time_init has been called move reset_tod_clock to early.c to make sure that the TOD clock is running when read_persistent_clock is invoked.
