[S390] avoid STCKF if running in ESA mode

2011-11-14T10:19:09+00:00

In ESA mode STCKF is not defined even if the facility bit is enabled.
To prevent an illegal operation we must also check if we run a 64 bit kernel.
To make the check perform well add the STCKF bit to the machine flags.

[S390] Introduce get_clock_fast()

2011-10-30T14:16:45+00:00

Add get_clock_fast() which uses the slightly faster stckf if available.
If stckf is not available fall back to stck, which has the same width.

[S390] time: let local_tick_enable/disable() reprogram the clock comparator

2011-01-05T11:47:25+00:00

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.

[S390] time: move local_tick_enable()/disable() to timex.h

2011-01-05T11:47:24+00:00

Move the two functions to timex.h where they make more sense than in
hardirq.h.
No functional change.

[S390] s390_hypfs: Add new attributes

2010-05-17T08:00:17+00:00

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

[S390] use inline assembly contraints available with gcc 3.3.3

2010-02-26T21:37:30+00:00

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.

[S390] introduce get_clock_monotonic

2009-09-11T08:29:42+00:00

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.

[S390] add read_persistent_clock

2009-04-14T13:37:27+00:00

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.
