Subject: x86,xen: use current->state helpers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=57b6b99bac045bece3b3892377e863b571314950;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86,xen: use current->state helpers

Call __set_current_state() instead of assigning the new state directly.
These interfaces also aid CONFIG_DEBUG_ATOMIC_SLEEP environments,
keeping track of who changed the state.
