* gcc-constprop.patch
In v4.20, 33e26418193f ("y2038: make do_gettimeofday() and get_seconds()
inline"), do_gettimeofdat() no longer exists as a stand alone function
in kernel/time/timekeeping.c.
* gcc-static-local-var-4.patch
Unlike on rhel-8.4, _always_inline put_aio_ring_file() is causing too
many inlines and results in modified, but not ftrace-able,
__do_sys_io_submit() and __do_sys_io_setup(). Remove the annotation
from this function.
* module.patch
In v4.20, 9ceddd9da134 ("knfsd: Allow lockless lookups of the exports"),
the nfs_exports_op seq_operations converted to RCU protected lookups.
Calling yield() from a kpatched e_show() results in a kernel warning,
"Voluntary context switch within RCU read-side critical section!"
Substitute with single_task_running(), which does not context switch or
have any other side effects.
In v5.10, ec6347bb4339 ("x86, powerpc: Rename memcpy_mcsafe() to
copy_mc_to_{user, kernel}()") did away with the mcsafe_key. Use
another exported static key like context_tracking_enabled.
In v5.13, a0e2bf7cb700 ("x86/paravirt: Switch time pvops functions to
use static_call()"), paravirt_sched_clock() was converted from a
paravirt call to a non-exported static call. Update the x86 code to
instead call __flush_tlb_local() (which is still a paravirt call).
