From 2faf153bb7346b7dfc895f916edf93a86297ec0a Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 21 Apr 2020 11:20:32 +0200 Subject: x86/tlb: Move __flush_tlb() out of line 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. As a first step, move __flush_tlb() out of line and hide the native function. The latter can be static when CONFIG_PARAVIRT is disabled. Consolidate the namespace while at it and remove the pointless extra wrapper in the paravirt code. No functional change.
