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
