lttng-modules: fix build against v5.10+
lttng-modules doesn't currently build against the lastest 5.10-rc versions. Upstream lttng does have fixes for the issues, but hasn't done a release that contains them yet. There are other patches on the 2.12.x branch, but I've skipped them for now as they aren't necessary for 5.10 builds, and can be picked up with the next full update. We also bump the dev-upstream hash to make them easier to pickup for those building from git.

12 ext4: fast commit recovery path
13
14 This patch adds fast commit recovery path support for Ext4 file
15 system. We add several helper functions that are similar in spirit to
16 e2fsprogs journal recovery path handlers. Example of such functions
17 include - a simple block allocator, idempotent block bitmap update
18 function etc. Using these routines and the fast commit log in the fast
19 commit area, the recovery path (ext4_fc_replay()) performs fast commit
20 log recovery.

12 kvm: x86/mmu: Add TDP MMU PF handler
13
14 Add functions to handle page faults in the TDP MMU. These page faults
15 are currently handled in much the same way as the x86 shadow paging
16 based MMU, however the ordering of some operations is slightly
17 different. Future patches will add eager NX splitting, a fast page fault
18 handler, and parallel page faults.
19
20 Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell
21 machine. This series introduced no new failures.

12 tracepoint: Optimize using static_call()
13
14 Currently the tracepoint site will iterate a vector and issue indirect
15 calls to however many handlers are registered (ie. the vector is
16 long).
17
18 Using static_call() it is possible to optimize this for the common
19 case of only having a single handler registered. In this case the
20 static_call() can directly call this handler. Otherwise, if the vector
21 is longer than 1, call a function that iterates the whole vector like
22 the current code.
