Evgeniy Stepanov 1f1a7a719d hwasan: add -hwasan-match-all-tag flag ... Sometimes instead of storing addresses as is, the kernel stores the address of a page and an offset within that page, and then computes the actual address when it needs to make an access. Because of this the pointer tag gets lost (gets set to 0xff). The solution is to ignore all accesses tagged with 0xff. This patch adds a -hwasan-match-all-tag flag to hwasan, which allows to ignore accesses through pointers with a particular pointer tag value for validity. Patch by Andrey Konovalov.
