#     powerpc/vdso32: fix CLOCK_MONOTONIC on PPC64
#     
#     Commit b5b4453e7912 ("powerpc/vdso64: Fix CLOCK_MONOTONIC
#     inconsistencies across Y2038") changed the type of wtom_clock_sec
#     to s64 on PPC64. Therefore, VDSO32 needs to read it with a 4 bytes
#     shift in order to retrieve the lower part of it.
#     
#     Fixes: b5b4453e7912 ("powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across Y2038")
