Make sure that seccomp filter won't be built when ARM OABI is in use,
since there is work needed to distinguish calling conventions. Until
that is done (which is likely never since OABI is deprecated), make
sure seccomp filter is unavailable in the OABI world.

This patch modifies existing IMA functions to retrieve the template name
or format specified in a matched policy rule and provide it to
ima_alloc_init_template(). The latter calls ima_get_template_desc()
to obtain the template descriptor to use for creating a new measurement
entry.

This patch replaces calls to ima_template_desc_current() in ima_api.c
and ima_main.c with ima_get_template_desc() as the former function
is called by the latter when passed arguments are both NULL. The patch
also declares the former function as static so that it will not be
longer available outside
This patch adds the support for 'ima_template' and 'ima_template_fmt'
policy options. They allow to define which template and, thus, which
information should be included in measurements entries generated from
events that match other rules' criteria.
With this feature, it is possible to include for
This patch adds a new helper to search a template descriptor by its format.

If DEBUG_SPINLOCK and DEBUG_LOCK_ALLOC are enabled spinlock_t on x86_64
is 72 bytes. For page->ptl they will be allocated from kmalloc-96 slab,
so we loose 24 on each. An average system can easily allocate few tens
thousands of page->ptl and overhead is significant.
Let's create a separate slab fo
