The uc_sigmask definition in the kernel differs from the one in the glibc, the kernel uc_sigmask has 64 bits while the glibc verison is 1024 bits. The extension of the ucontext structure for 64-bit register support for 31-bit compat processes added a new field uc_gprs_high which starts 8 bytes after the uc_sigmask field. As the glibc view of the ucontext assumes a size of 128 bytes for uc_sigmask add a 120 byte padding to the kernel structure ucontext_extended after the 8 byte uc_sigmask.
