iomap: constify ioreadX() iomem argument (as in generic implementation)
Patch series "iomap: Constify ioreadX() iomem argument", v3.
The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take pointer to const.
This patch (of 4):
The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among architectures.

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of:
kzalloc(a * b, gfp)
with: kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.
The Coccinelle script used for this was:

ARM: shmobile: wait for MSTP clock status to toggle, when enabling it
On r-/sh-mobile SoCs MSTP clocks are used by the runtime PM to dynamically enable and disable peripheral clocks. To make sure the clock has really started we have to read back its status register until it confirms success.

sh: clkfwk: Use shared sh_clk_div_enable/disable().
This introduces a new flag for clocks that need to have their divisor ratio set back to their initial mask at disable time to prevent interactivity problems with the clock stop bit (presently div6 only). With this in place it's possible to handle the corner case on top of the div4 op without any particular need for leaving things split out.
