Due to an issue in the kaslr address resolution in makedumpfile, we may get the following error when collecting a dump:

Excluding unnecessary pages : [ 46.3 %] / __vtop4_x86_64[ 39.341233]: Can't get a valid pmd_pte.
readmem: Can't convert a virtual address(ffffe05cb4000000) to physical address.
readmem: type_addr: 0, addr:ffffe05cb4000000, size:32768
__exclude_unnecessary_pages: Can't read the buffer of struct page.
create_2nd_bitmap: Can't exclude unnecessary pages.

This is believed to be fixed by commit: 3222d4ad04c6 ("x86_64: fix get_kaslr_offset_x86_64() to return kaslr_offset correctly"). This LP keeps track of Test/SRU for this commit.
