[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [XEN PATCH v7 1/4] x86/vmx: address violations of MISRA C:2012 Rule 7.2
From: Gianluca Luparini <gianluca.luparini@xxxxxxxxxxx>
The xen sources contains violations of MISRA C:2012 Rule 7.2 whose
headline states:
"A 'u' or 'U' suffix shall be applied to all integer constants
that are represented in an unsigned type".
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'

No changes in v5, v6 and v7.
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'
