staging/lustre/clio: optimize read ahead code

It used to check each page in the readahead window is covered by
a lock underneath, now cpo_page_is_under_lock() provides @max_index
to help decide the maximum ra window. @max_index can be modified by
OSC to extend the maximum lock region, to align stripe boundary at
LOV, and to make sure the readahead region at least covers read
region at LLITE layer.

After this is done, usually readahead code calls
cpo_page_is_under_lock() for each stripe.

staging: lustre: libcfs: replace direct HZ access with kernel APIs

On some customers' systems, the kernel was compiled with HZ defined
to 100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined constant
HZ.

Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.

These kernel APIs include:
  jiffies_to_msecs()
  jiffies_to_usecs()
  jiffies_to_timespec()
  msecs_to_jiffies()
  usecs_to_jiffies()
  timespec_to_jiffies()

 And here are some samples of the replacement:
  HZ            -> msecs_to_jiffies(MSEC_PER_SEC)
  n * HZ        -> msecs_to_jiffies(n * MSEC_PER_SEC)
  HZ / n        -> msecs_to_jiffies(MSEC_PER_SEC / n)
  n / HZ        -> jiffies_to_msecs(n) / MSEC_PER_SEC
  n / HZ * 1000 -> jiffies_to_msecs(n)

This patch replaces the direct HZ access in the libcfs module.

staging: comedi: ni_tio: remove BUG() checks for ni_tio_get_clock_src()

This function calls some helper functions to convert the counter variant
specific clock select bits into the generic enum ni_gpct_clock_source_bits
equivelent. These helper functions currently BUG() if the clock select
bits are invalid.

It then calls ni_tio_clock_period_ps() to figure out the clock period
based on the generic clock source. This function could also BUG() if
the prescale bits are invalid.

In reality this should never happen but refactor the code to return
-EINVAL instead and remove the BUG() checks.

These functions are also called by ni_tio_set_sync_mode(). When this
function is called by ni_tio_set_clock_src() the counter select bits
have already been validated.
