The kernel abi was finally merged into 5.10.
Changes for v5:
* Actually include the revamp for TARGET_TAGGED_ADDRESSES,
which got lost at some point before posting v4.
Patches lacking review are only the new ones:
0011-exec-Introduce-cpu_untagged_addr.patch
0012-exec-Use-cpu_untagged_addr-in-g2h-split-out-g2h_u.patch
0013-linux-user-Explicitly-untag-memory-management-sys.patch
0014-linux-user-Use-guest_range_valid-in-access_ok.patch
0015-exec-Rename-guest_-addr-range-_valid-to-_untagged.patch
0016-linux-user-Use-cpu_untagged_addr-in-access_ok-spl.patch
0017-linux-user-Move-lock_user-et-al-out-of-line.patch
0018-linux-user-Fix-types-in-uaccess.c.patch
0019-linux-user-Handle-tags-in-lock_user-unlock_user.patch
Changes for v4:
* Revamp "Add support for TARGET_TAGGED_ADDRESSES". There are now two
sets of functions in include/exec/, one for tagged and one for
untagged addresses. The former takes a CPUState, and does not
assume current_cpu is a thing. So much for the generic bits...
However, use of current_cpu remains, pushed down to lock_user.
Changing everything that touches that, or get/put_user, is daunting.
* Fix tbi0 vs tbi1 for linux-user.
This had a number of cascading effects.
* Adjust when async errors are noticed.
Changes for v3:
* Split out type changes to separate patches.
* Add doc comments; tweak alloc so that the !PAGE_VALID case is clear.
* Do not overlap PAGE_TARGET_2 with PAGE_RESERVED.
* Use syndrome.h, arm_deliver_fault.
