[RFT 00/13] iomap: Constify ioreadX() iomem argument
...readl/writel, this is what we do in asm-generic:
>
> static inline u32 __raw_readl(const volatile void __iomem *addr)
> {
> return *(const volatile u32 __force *)addr;
> }
SuperH is another example:
1. ioread8_rep(void __iomem *addr, void *dst, unsigned long count)
calls mmio_insb()
2. static inline void mmio_insb(void __iomem *addr, u8 *dst, int count)
calls __raw_readb()
3. #define __raw_readb(a) (__chk_io_ptr(a), *(volatile u8 __force *)(a))
Even if interface was not marked as volatile, in fact its implementation
was casting to volatile.

[PATCH v3 0/4] iomap: Constify ioreadX() iomem argument
Hi,
Multiple architectures are affected in the first patch and all further
patches depend on the first.
Maybe this could go in through Andrew Morton's tree?
Changes since v2
================
1. Drop all non-essential patches (cleanups),
2. Update also drivers/sh/clk/cpg.c .

1. Constify also ioreadX_rep() and mmio_insX(),
2. Squash lib+alpha+powerpc+parisc+sh into one patch for bisectability,
3. Add Geert's review,
4. Re-order patches so all optional driver changes are at the end.
