Commit 1d9fe6b97 ("clk: divider: Fix best div calculation for power-of-two and
table dividers") introduces a regression in its _table_round_up function.
When the divider passed to this function is greater than the max divider
available in the table, this function returns table's max divider.
Problem is that it causes an infinite loop in clk_divider_bestdiv() because
_next_div() will never return a value greater than maxdiv.
Instead of returning table's max divider, this patch returns INT_MAX.

The patch 3e374919b3 is supposed to fix the
problem where kmem_cache_create incorrectly reports duplicate cache name
and fails. The problem is described in the header of that patch.
However, the patch doesn't really fix the problem because of these
reasons:
* the logic to test for debugging is reversed. It was intended to perform
the check only if slub debugging is enabled (which implies that caches
with the same parameters are not merged). Therefore, there should be
#if !defined(CONFIG_SLUB) || defined(CONFIG_SLUB_DEBUG_ON)
The current code has the condition reversed and performs the test if
debugging is disabled.
* slub debugging may be enabled or disabled based on kernel command line,
CONFIG_SLUB_DEBUG_ON is just the default settings. Therefore the test
based on definition of CONFIG_SLUB_DEBUG_ON is unreliable.
This patch fixes the problem by removing the test
"!defined(CONFIG_SLUB_DEBUG_ON)". Therefore, duplicate names are never
checked if the SLUB allocator is used.
Note to stable kernel maintainers: when backporint this patch, please
backport also the patch 3e374919b3.

This patch adds three more test cases:
1) long jumps with holes of unreachable code
2) ret x
3) ldx + ret x
All three tests are for classical BPF and to make sure that
any changes will not break some exotic behaviour that exists
probably since decades. The last two tests are expected to
fail by the BPF checker already, as in classic BPF only K
or A are allowed to be returned. Thus, there are now 52 test
cases for BPF.

The sk_unattached_filter_create() API is used by BPF filters that
are not directly attached or related to sockets, and are used in
team, ptp, xt_bpf, cls_bpf, etc. As such all users do their own
internal managment of obtaining filter blocks and thus already
have them in kernel memory and set up before calling into
sk_unattached_filter_create(). As a result, due to __user annotation
in sock_fprog, sparse triggers false positives (incorrect type in
assignment [different address space]) when filters are set up before
passing them to sk_unattached_filter_create(). Therefore, let
sk_unattached_filter_create() API use sock_fprog_kern to overcome
this issue.
