-Subject: [PATCH] modules: replace SUBDIRS with M
-
-Since commit 0126be38d988 ("kbuild: announce removal of SUBDIRS if used")
-in v5.0-rc1, using SUBDIRS when building out of tree modules produces
-a deprecation warning. As M used to work since pretty much ever, use it
-unconditionally.

-Subject: [PATCH] vmmon: totalram_pages is a function since 5.0
-
-Since commit ca79b0c211af ("mm: convert totalram_pages and totalhigh_pages
-variables to atomic") in v5.0-rc1, totalram_pages() is an accessor function
-and the actual variable is an atomic.

-Subject: [PATCH] vmmon: bring back the do_gettimeofday() helper
-
-The do_gettimeofday() helper was removed by commit e4b92b108c6c
-("timekeeping: remove obsolete time accessors") in v5.0-rc1. Bring it back
-for users in vmmon-only/linux/hostif.c.
-
-This feels like a quick and clumsy band aid to allow build with post-4.20
-kernels. On a closer look, the whole gymnastics around uptimeState and
-HostIFReadUptimeWork() with jiffies and wall time checking and correcting
-each other seems to be a workaround for an absence of high resolution
-monotonic time. Considering ktime_get_ts64() is available since 3.17 and
-before that, ktime_get_ts() since 2.6.17, perhaps the time has come to
-clean all this machinery up. But something like this would be beyond the
-scope of this repository.

-Subject: [PATCH] modules: handle access_ok() with two arguments
-
-Since commit 96d4f267e40f ("Remove 'type' argument from access_ok()
-function") in v5.0-rc1, the type argument of access_ok() was dropped.
-The same commit also dropped macros VERIFY_READ and VERIFY_WRITE so check
-for their existence on pre-5.0 kernels to allow build against kernels with
-this change backported.
