[Minios-devel] [PATCH v2 18/47] arm64: mm.c: fix the compiler error

[Huang Shijie <shijie.huang@xxxxxxx>]

The @_end is (unsigned int) type, and we will meet a compilor error:

 ---------------------------------------
  mm.c: In function ‘arch_init_mm’:
  mm.c:59:24: error: cast from pointer to integer of different size 
[-Werror=pointer-to-int-cast]
       unsigned int end = (unsigned int) &_end;
 ---------------------------------------

This patch converts the type to uintptr_t, and fix the error.
