Log Message:
remove KERNHIST_INIT_STATIC().  it stradles the line between usable
early in boot and broken early in boot by requiring a partly static
structure with another structure that must be present by the time
any uses are performed.  theoretically platform code could allocate
a chunk while seting up memory and assign it here, giving a dynamic
sizing for the entry list, but the reality is that all users have
a statically allocated entry list as well.

the existing KERNHIST_LINK_STATIC() is used in conjunction with
KERNHIST_INITIALIZER() instead.

this stops a NULL pointer deref when the _LOG() macro is called
before the storage is linked in, which happens with GCC 10 on OCTEON
with UVMHIST enabled, crashing in very early kernel init.
