This option was created in commit 554b0004d0ec4 ("vtime: Add
HAVE_VIRT_CPU_ACCOUNTING_GEN Kconfig") for architectures to indicate
they support the 64-bit cputime_t required for VIRT_CPU_ACCOUNTING_GEN.
The cputime_t type has since been removed, so this doesn't have any
meaning. Remove it.
Well, cputime_t has disappeared but not the u64 type used
for task/cpu time accounting.
But now we have the vtime seqcount. Though we already had it
when we introduced that Kconfig switch so I can't remember why
this was necessary :-(
It _looks_ OK but I might be missing something...
Thanks.
