Add the 'U' suffix to integers literals with unsigned type. For the sake of uniformity, the following changes are made: - add the 'U' suffix to macros near 'CPU_BASED_ACTIVATE_SECONDARY_CONTROLS' and 'SECONDARY_EXEC_NOTIFY_VM_EXITING' macros in 'vmcs.h' - add the 'U' suffix to macros near 'INTR_INFO_VALID_MASK' macro in 'vmx.h' Signed-off-by: Gianluca Luparini Signed-off-by: Simone Ballarin Reviewed-by: Stefano Stabellini Reviewed-by: Jan Beulich --- No changes in v5 and v6. Changes in v4: - change commit headline Changes in v3: - change 'Signed-off-by' ordering - change commit message - remove unnecessary changes in 'vvmx.c' - add 'uint32_t' casts in 'vvmx.c' - add missing 'U' in 'vmcs.h' macros - change macro to '(1u << 31)' in 'vmx.h' - remove unnecessary changes to 'vmx.h' Changes in v2: - minor change to commit title - change commit message - remove unnecessary changes in 'vpmu_intel.c' and 'vmx.h' - add 'ULL' suffix in 'vpmu_intel.c' - add zero-padding to constants in 'vmx.h' - add missing 'U' in 'vmx.h' --- xen/arch/x86/cpu/vpmu_intel.c | 2 +- xen/arch/x86/hvm/vmx/vmcs.c | 6 +- xen/arch/x86/hvm/vmx/vvmx.c | 8 +-- xen/arch/x86/include/asm/hvm/vmx/vmcs.h | 84 ++++++++++++------------- xen/arch/x86/include/asm/hvm/vmx/vmx.h | 16 ++--- 5 files changed, 58 insertions(+), 58 deletions(-) diff --git a/xen/arch/x86/cpu/vpmu_intel.c b/xen/arch/x86/cpu/vpmu_intel.c index fa5b40c65c..6330c89b47 100644 --- a/xen/arch/x86/cpu/vpmu_intel.c +++ b/xen/arch/x86/cpu/vpmu_intel.c @@ -945,7 +945,7 @@ const struct arch_vpmu_ops *__init core2_vpmu_init(void) fixed_counters_mask = ~((1ull << core2_get_bitwidth_fix_count()) - 1);
