Subject: [patch 00/15] x86/tlb: Unexport per-CPU tlbstate
Date: Sun, 19 Apr 2020 22:31:37 +0200
Message-ID: <20200419203137.214111265@linutronix.de> (raw)

The per-CPU tlbstate contains sensitive information which should be really
only accessible in core code. It is exported to modules because some inline
functions which are required by KVM need access to it.

The following series creates regular exported functions for the few things
which are needed by KVM and hides the struct definition and some low level
helpers from modules.

The series is also available from git:

   git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel x86/tlb

Thanks,

	tglx
