[PATCH v7 11/12] x86/paravirt: Adapt assembly for PIE support

2019-05-20 Thread Thomas Garnier
From: Thomas Garnier if PIE is enabled, switch the paravirt assembly constraints to be compatible. The %c/i constrains generate smaller code so is kept by default. Position Independent Executable (PIE) support will allow to extend the KASLR randomization range below 0x8000. Signed-o
