[xtensa-cvscommit] linux/arch/xtensa/kernel process.c,1.6,1.7

[<za...@us...>]

Update of /cvsroot/xtensa/linux/arch/xtensa/kernel
In directory sc8-pr-cvs1:/tmp/cvs-serv24901a/linux/arch/xtensa/kernel

Modified Files:
	process.c 
Log Message:
Added syscall_nr to xtensa_gregset_t (and, thus, elf_gregset_t).
Added access to syscall_nr via ptrace (PTRACE_GETREGS/PTRACE_SETREGS).
Fixed arch/xtensa/Makefile:
      When LIBGCC is defined, the host compiler is used instead of the
      cross compiler.
