Subject: nohz: Drop generic vtime obsolete dependency on CONFIG_64BIT
X-Git-Tag: Ubuntu-snapdragon-4.4.0-1029.32~9861^2~12^2~1
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=ff3fb2541246a83ce56c61d14df30b7a22e4302b;p=mirror_ubuntu-zesty-kernel.git

nohz: Drop generic vtime obsolete dependency on CONFIG_64BIT

The CONFIG_64BIT requirement on vtime can finally be removed
since we now depend on HAVE_VIRT_CPU_ACCOUNTING_GEN which
already takes care of the arch ability to handle nsecs based
cputime_t safely.
