[Minios-devel] [PATCH v3 01/43] mini-os: fix the wrong parameter for map_free() in init_page_allocator()

[Huang Shijie <shijie.huang@xxxxxxx>]

The @r_min has become to virtual address, so it is wrong to use PHYS_PFN()
for @r_min.

This patch uses the virt_to_pfn() to fix it.

The bug is introduced by:
 "2526e9bbe52328a7 mini-os: get physical memory map"
