| Subject: sparc64: remove unnecessary macros from spinlock_64.h |
| |
| From: Mikael Pettersson <mikpe@it.uu.se> |
| |
| commit a0fba3eb059e73fed2d376a901f8117734c12f1f upstream. |
| |
| The sparc64 spinlock_64.h contains a number of operations defined |
| first as static inline functions, and then as macros with the same |
| names and parameters as the functions. Maybe this was needed at |
| some point in the past, but now nothing seems to depend on these |
| macros (checked with a recursive grep looking for ifdefs on these |
| names). Other archs don't define these identity-macros. |
| |
| So this patch deletes these unnecessary macros. |
| |
| Compile-tested with sparc64_defconfig. |
