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.

Hi,
Could we tidy this? I don't know what tree it can go in, timers,
sched, asm-generic, probably doesn't matter.
The only thing this actually does is gate VIRT_CPU_ACCOUNTING_GEN and
NO_HZ_FULL so if your arch has some other issue that requires this
then the documentation needs to change. Any concerns from the archs?
I.e., 32-bit that does *not* define HAVE_VIRT_CPU_ACCOUNTING_GEN
which looks to be:
arc
hexagon
loongarch 32-bit with SMP
m68k
microblaze
mips 32-bit with SMP
nios2
openrisc
parisc 32-bit
riscv 32-bit
Nothing's jumping out, though I haven't tested this yet so I'm not 100%.
I assume this isn't aimed for this merge window, given the timing?
Probably best to give this sort of thing time to bake in linux-next, but
I doubt anyone is even paying attention to rv32/NO_HZ_FULL so no big
deal either way on my end.

sh
sparc 32-bit
um 32-bit
x86 32-bit
Thanks,
Nick
