| /* Despite the fact that <linux/types.h> defines sigset_t as a 32-bit type, |
| * the ARM kernel *really* expects a 64-bit signal set type during syscalls. |
| * |
| * The reason for this is that the kernel headers have a different definition |
| * for sigset_t depending on the value of the __KERNEL__ macro. When we cleanup |
| * the headers, before placing them under bionic/libc/kernel/, this macro is |
| * optimized as undefined, to the 32-bit definition stays. |
| * |
| * Ironically, the reason the kernel headers do this is to accomodate old |
| * versions of GLibc. More recent versions provide complete wrappers for the |
| * corresponding kernel types so don't have this problem (their sigset_t can |
| * always hold up to 1024 signals, independent of the platform). |
