When building the frequencies table we convert the value in the DTS to
megahertz and loose precision. While it's not a problem for most of the
DTS it is when the expected frequency value is strict down to the hertz.
So it's either we don't truncate the value and have some ugly and long
values in the sysctls or we just find the closest frequency.
Do the latter.

When register_sysctl_table() is unavailable we fail to properly
unregister sysctl entries under "kernel/spl".
This leads to errors like the following when spl is unloaded/reloaded,
making impossible to properly reload the spl module:
[ 746.995704] sysctl duplicate entry: /kernel/spl/kmem/slab_kvmem_total
Fix by cleaning up all the sub-entries inside "kernel/spl" when the
spl module is unloaded.

When two SYSINITs tied for (subsystem, order), they were executed in

set.
Note that while this changes struct sysinit, it doesn't affect ABI
since SLIST_ENTRY and STAILQ_ENTRY are compatible (in both cases a
single pointer to the next element).

Commit 3f686532c9 tried to fix an issue with not properly starting
at the first page in the sg list to prevent a panic. This worked but
with the side effect of incrementing "s" during the final iteration
causing it to be NULL since the list had ended.
In cases non-DEBUG kernels this causes a panic with drm-5.15, since
"s" is NULL when we later pass it to sg_mark_end().
This change decouples the iteration sg from the return value so that
it is never incremented past the final page in the chain.

When using printm(), one should always pass a scratch pointer to it.
This is achieved by calling printm with memref
BEGIN { printm(fixed_len, memref(ptr, var_len)); }
which will return a pointer to the DTrace scratch space of size
sizeof(uintptr_t) * 2. However, one can easily call printm() as follows
BEGIN { printm(10, (void *)NULL); }
and panic the kernel as a result. This commit does two things:
(1) adds a new macro DTRACE_INSCRATCHPTR(mstate, ptr, howmany) which
checks if a certain pointer is in the DTrace scratch space;
(2) uses DTRACE_INSCRATCHPTR() to implement a check on printm()'s DIFO
return value in order to avoid the panic and sets CPU_DTRACE_BADADDR
if the address is not in the scratch space.
