-Subject: [PATCH 01/12] kaiser: fix compile error without vsyscall
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Tobias noticed a compile error on 4.4.115, and it's the same on 4.9.80:
-arch/x86/mm/kaiser.c: In function ‘kaiser_init’:
-arch/x86/mm/kaiser.c:348:8: error: ‘vsyscall_pgprot’ undeclared
- (first use in this function)
-
-It seems like his combination of kernel options doesn't work for KAISER.
-X86_VSYSCALL_EMULATION is not set on his system, while LEGACY_VSYSCALL
-is set to NONE (LEGACY_VSYSCALL_NONE=y). He managed to get things
-compiling again, by moving the 'extern unsigned long vsyscall_pgprot'
-outside of the preprocessor statement. This works because the optimizer
-removes that code (vsyscall_enabled() is always false) - and that's how
-it was done in some older backports.
