Thomas Gleixner d8f0b35331 x86/cpu: Uninline CR4 accessors ... cpu_tlbstate is exported because various TLB-related functions need access to it, but cpu_tlbstate is sensitive information which should only be accessed by well-contained kernel functions and not be directly exposed to modules. The various CR4 accessors require cpu_tlbstate as the CR4 shadow cache is located there. In preparation for unexporting cpu_tlbstate, create a builtin function for manipulating CR4 and rework the various helpers to use it. No functional change. [ bp: push the export of native_write_cr4() only when CONFIG_LKTDM=m to the last patch in the series. ] Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Alexandre Chartre <alexandre.chartre@oracle.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20200421092558.939985695@linutronix.de		2020-04-24 18:46:42 +02:00
