Subject: [kvm-unit-tests PATCH] cstart: Fix typo in i386's cstart assembly
Date: Mon, 13 Jul 2020 21:19:05 -0700 [thread overview]
Message-ID: <20200714041905.12848-1-sean.j.christopherson@intel.com> (raw)
Replace a '%' with a '$' to encode a literal in when initializing CR4.
This fixes the build on i386 as gcc complains about a non-existent
register.
x86/cstart.S: Assembler messages:
x86/cstart.S:128: Error: bad register name `%(1<<4)'
Makefile:101: recipe for target 'x86/cstart.o' failed
Fixes: d86ef58519645 ("cstart: do not assume CR4 starts as zero")
Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com>
