Merge tag 'timers-vdso-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip

Pull vdso updates from Thomas Gleixner:

 - Remove the redundant CONFIG_GENERIC_TIME_VSYSCALL after converting
   the remaining users over.

 - Rework and sanitize the MIPS VDSO handling, so it does not handle the
   time related VDSO if there is no VDSO capable clocksource available.
   Also stop mapping VDSO data pages unconditionally even if there is no
   usage possible.

* tag 'timers-vdso-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip:
  MIPS: VDSO: Fold MIPS_CLOCK_VSYSCALL into MIPS_GENERIC_GETTIMEOFDAY
  MIPS: VDSO: Gate microMIPS restriction on GCC version
  MIPS: VDSO: Fold MIPS_DISABLE_VDSO into MIPS_GENERIC_GETTIMEOFDAY
  clocksource/drivers/mips-gic-timer: Only use VDSO_CLOCKMODE_GIC when it is a available
  MIPS: csrc-r4k: Only use VDSO_CLOCKMODE_R4K when it is a available
  MIPS: VDSO: Only map the data pages when the vDSO is used
  MIPS: Introduce Kconfig MIPS_GENERIC_GETTIMEOFDAY
  vdso/datastore: Always provide symbol declarations
  MAINTAINERS: Add include/linux/vdso_datastore.h to vDSO block
  vdso/gettimeofday: Rename __arch_get_vdso_u_timens_data()
  vdso/treewide: Drop GENERIC_TIME_VSYSCALL
  vdso/vsyscall: Gate update_vsyscall() behind CONFIG_GENERIC_GETTIMEOFDAY
  riscv: vdso: Drop CONFIG_GENERIC_TIME_VSYSCALL guard around syscall fallbacks
