Hello everyone,

I just noticed this yesterday and I can't seem to figure it out.

In linux-4.14, vmallocinfo looked like this:

$ cat /proc/vmallocinfo
0xc2800000-0xc2802000    8192 of_iomap+0x19/0x22 phys=0xe8201000 ioremap
0xc2802000-0xc2804000    8192 of_iomap+0x19/0x22 phys=0xe8202000 ioremap
0xc2804000-0xc2806000    8192 l2x0_of_init+0x3f/0x174 phys=0x3ffff000 ioremap
0xc2806000-0xc2808000    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0xc2808000-0xc280a000    8192 unpurged vm_area
0xc280a000-0xc280c000    8192 unpurged vm_area
0xc280c000-0xc280e000    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0xc280e000-0xc2810000    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0xc2810000-0xc2812000    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap


However as of linux-4.15, it now looks like this:

$ cat /proc/vmallocinfo
0x2423e1ec-0x1d348857    8192 of_iomap+0x19/0x22 phys=0xe8201000 ioremap
0x1d348857-0x52c37840    8192 of_iomap+0x19/0x22 phys=0xe8202000 ioremap
0x52c37840-0x402f3b08    8192 l2x0_of_init+0x3f/0x174 phys=0x3ffff000 ioremap
0x402f3b08-0x06d553ef    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0x06d553ef-0xf6dfcceb    8192 unpurged vm_area
0xf6dfcceb-0xd99b6570    8192 unpurged vm_area
0xd99b6570-0xa32d8fae    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0xa32d8fae-0xffd15855    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap
0xffd15855-0x9d2cc6ea    8192 of_iomap+0x19/0x22 phys=0xfcfe0000 ioremap


The virtual addresses are all wrong!

I can't seem to find any patches or code changes that would explain this.

Does anyone have an idea why it now looks like this?

Thanks,
Chris
