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.

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.
