I've gone through the remaining uses of time_t etc and come up with a set of 90 patches of varying complexity and importance, to the point of being able to remove the old time_t/timeval/timespec from the kernel headers completely. This set includes the eight patches that I think should be merged right away and backported into stable kernels if possible. Please apply individual patches to the respective maintainer trees for either v5.4 or v5.5 as appropriate. For reference, the full series of 90 patches can be found at https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame Arnd Arnd Bergmann (8): y2038: timex: remove incorrect time_t truncation timekeeping: optimize ns_to_timespec64 powerpc: fix vdso32 for ppc64le ipmi: kill off 'timespec' usage again netfilter: xt_time: use time64_t lp: fix sparc64 LPSETTIMEOUT ioctl ppdev: fix PPGETTIME/PPSETTIME ioctls Input: input_event: fix struct padding on sparc64 arch/powerpc/kernel/vdso32/gettimeofday.S | 2 +- drivers/char/ipmi/ipmi_si_intf.c | 40 ++++++++--------------- drivers/char/lp.c | 4 +++ drivers/char/ppdev.c | 16 ++++++--- drivers/input/evdev.c | 3 ++ drivers/input/misc/uinput.c | 3 ++ include/uapi/linux/input.h | 1 + kernel/time/ntp.c | 2 +- kernel/time/time.c | 21 +++++++----- net/netfilter/xt_time.c | 19 ++++++----- 10 files changed, 61 insertions(+), 50 deletions(-) Cc: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx> Cc: Paul Mackerras <paulus@xxxxxxxxx> Cc: Michael Ellerman <mpe@xxxxxxxxxxxxxx> Cc: Corey Minyard <minyard@xxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx> Cc: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx> Cc: John Stultz <john.stultz@xxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: Stephen Boyd <sboyd@xxxxxxxxxx> Cc: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> Cc: Jozsef Kadlecsik <kadlec@xxxxxxxxxxxxx> Cc: Florian Westphal <fw@xxxxxxxxx> Cc: "David S.
