-/* This file includes Linux-specific support functions common to the
- * coredumper and the thread lister; primarily, this is a collection
- * of direct system calls, and a couple of symbols missing from
- * standard header files.
- * There are a few options that the including file can set to control
- * the behavior of this file:
- *
- * SYS_CPLUSPLUS:
- *   The entire header file will normally be wrapped in 'extern "C" { }",
- *   making it suitable for compilation as both C and C++ source. If you
- *   do not want to do this, you can set the SYS_CPLUSPLUS macro to inhibit
- *   the wrapping. N.B. doing so will suppress inclusion of all prerequisite
- *   system header files, too. It is the caller's responsibility to provide
- *   the necessary definitions.
- *
- * SYS_ERRNO:
- *   All system calls will update "errno" unless overriden by setting the
- *   SYS_ERRNO macro prior to including this file. SYS_ERRNO should be
- *   an l-value.
- *
- * SYS_INLINE:
- *   New symbols will be defined "static inline", unless overridden by
- *   the SYS_INLINE macro.
- *
- * SYS_LINUX_SYSCALL_SUPPORT_H
- *   This macro is used to avoid multiple inclusions of this header file.
- *   If you need to include this file more than once, make sure to
- *   unset SYS_LINUX_SYSCALL_SUPPORT_H before each inclusion.
- *
- * SYS_PREFIX:
- *   New system calls will have a prefix of "sys_" unless overridden by
- *   the SYS_PREFIX macro. Valid values for this macro are [0..9] which
- *   results in prefixes "sys[0..9]_". It is also possible to set this
- *   macro to -1, which avoids all prefixes.
- *
- * This file defines a few internal symbols that all start with "LSS_".
- * Do not access these symbols from outside this file. They are not part
- * of the supported API.
- *
- * NOTE: This is a stripped down version of the official opensource
- * version of linux_syscall_support.h, which lives at
- *    http://code.google.com/p/linux-syscall-support/
- * It includes only the syscalls that are used in perftools, plus a
- * few extra.  Here's the breakdown:
- * 1) Perftools uses these: grep -rho 'sys_[a-z0-9_A-Z]* *(' src | sort -u
- *      sys__exit(
- *      sys_clone(
- *      sys_close(
- *      sys_fcntl(
- *      sys_fstat(
- *      sys_futex(
- *      sys_futex1(
- *      sys_getcpu(
- *      sys_getdents64(
- *      sys_getppid(
- *      sys_gettid(
- *      sys_lseek(
- *      sys_mmap(
- *      sys_mremap(
- *      sys_munmap(
- *      sys_open(
- *      sys_pipe(
- *      sys_prctl(
- *      sys_ptrace(
- *      sys_ptrace_detach(
- *      sys_read(
- *      sys_sched_yield(
- *      sys_sigaction(
- *      sys_sigaltstack(
- *      sys_sigdelset(
- *      sys_sigfillset(
- *      sys_sigprocmask(
- *      sys_socket(
- *      sys_stat(
- *      sys_waitpid(
- * 2) These are used as subroutines of the above:
- *      sys_getpid       -- gettid
- *      sys_kill         -- ptrace_detach
- *      sys_restore      -- sigaction
- *      sys_restore_rt   -- sigaction
- *      sys_socketcall   -- socket
- *      sys_wait4        -- waitpid
- * 3) I left these in even though they're not used.  They either
- * complement the above (write vs read) or are variants (rt_sigaction):
- *      sys_fstat64
- *      sys_llseek
- *      sys_mmap2
- *      sys_openat
- *      sys_getdents
- *      sys_rt_sigaction
- *      sys_rt_sigprocmask
- *      sys_sigaddset
- *      sys_sigemptyset
- *      sys_stat64
- *      sys_write

-/* As glibc often provides subtly incompatible data structures (and implicit
- * wrapper functions that convert them), we provide our own kernel data
- * structures for use by the system calls.
- * These structures have been developed by using Linux 2.6.23 headers for
- * reference. Note though, we do not care about exact API compatibility
- * with the kernel, and in fact the kernel often does not have a single
- * API that works across architectures. Instead, we try to mimic the glibc
- * API where reasonable, and only guarantee ABI compatibility with the
- * kernel headers.
- * Most notably, here are a few changes that were made to the structures
- * defined by kernel headers:
- *
- * - we only define structures, but not symbolic names for kernel data
- *   types. For the latter, we directly use the native C datatype
- *   (i.e. "unsigned" instead of "mode_t").
- * - in a few cases, it is possible to define identical structures for
- *   both 32bit (e.g. i386) and 64bit (e.g. x86-64) platforms by
- *   standardizing on the 64bit version of the data types. In particular,
- *   this means that we use "unsigned" where the 32bit headers say
- *   "unsigned long".
- * - overall, we try to minimize the number of cases where we need to
- *   conditionally define different structures.
- * - the "struct kernel_sigaction" class of structures have been
- *   modified to more closely mimic glibc's API by introducing an
- *   anonymous union for the function pointer.
- * - a small number of field names had to have an underscore appended to
- *   them, because glibc defines a global macro by the same name.
