+ * enum x86_hardware_subarch - x86 hardware subarchitecture
+ *
+ * The x86 hardware_subarch and hardware_subarch_data were added as of the x86
+ * boot protocol 2.07 to help distinguish and support custom x86 boot
+ * sequences. This enum represents accepted values for the x86
+ * hardware_subarch.  Custom x86 boot sequences (not X86_SUBARCH_PC) do not
+ * have or simply *cannot* make use of natural stubs like BIOS or EFI, the
+ * hardware_subarch can be used on the Linux entry path to revector to a
+ * subarchitecture stub when needed. This subarchitecture stub can be used to
+ * set up Linux boot parameters or for special care to account for nonstandard
+ * handling of page tables.
+ *
+ * These enums should only ever be used by x86 code, and the code that uses
+ * it should be well contained and compartmentalized.
+ *
+ * KVM and Xen HVM do not have a subarch as these are expected to follow
+ * standard x86 boot entries. If there is a genuine need for "hypervisor" type
+ * that should be considered separately in the future. Future guest types
+ * should seriously consider working with standard x86 boot stubs such as
+ * the BIOS or EFI boot stubs.
+ *
+ * WARNING: this enum is only used for legacy hacks, for platform features that
+ *	    are not easily enumerated or discoverable. You should not ever use
+ *	    this for new features.
+ *
+ * @X86_SUBARCH_PC: Should be used if the hardware is enumerable using standard
+ *	PC mechanisms (PCI, ACPI) and doesn't need a special boot flow.
+ * @X86_SUBARCH_LGUEST: Used for x86 hypervisor demo, lguest, deprecated
+ * @X86_SUBARCH_XEN: Used for Xen guest types which follow the PV boot path,
+ * 	which start at __asm__ startup_xen() entry point and later jump to the C
+ * 	xen_start_kernel() entry point. Both domU and dom0 type of guests are
+ * 	currently supported through this PV boot path.
+ * @X86_SUBARCH_INTEL_MID: Used for Intel MID (Mobile Internet Device) platform
+ *	systems which do not have the PCI legacy interfaces.
+ * @X86_SUBARCH_CE4100: Used for Intel CE media processor (CE4100) SoC
+ * 	for settop boxes and media devices, the use of a subarch for CE4100
+ * 	is more of a hack...

+ * @run:	struct sgx_enclave_run, must be non-NULL
+ *
+ * NOTE: __vdso_sgx_enter_enclave() does not ensure full compliance with the
+ * x86-64 ABI, e.g. doesn't handle XSAVE state.  Except for non-volatile
+ * general purpose registers, EFLAGS.DF, and RSP alignment, preserving/setting
+ * state in accordance with the x86-64 ABI is the responsibility of the enclave
+ * and its runtime, i.e. __vdso_sgx_enter_enclave() cannot be called from C
+ * code without careful consideration by both the enclave and its runtime.
+ *
+ * All general purpose registers except RAX, RBX and RCX are passed as-is to the
+ * enclave.  RAX, RBX and RCX are consumed by EENTER and ERESUME and are loaded
+ * with @function, asynchronous exit pointer, and @run.tcs respectively.
+ *
+ * RBP and the stack are used to anchor __vdso_sgx_enter_enclave() to the
+ * pre-enclave state, e.g. to retrieve @run.exception and @run.user_handler
+ * after an enclave exit.  All other registers are available for use by the
+ * enclave and its runtime, e.g. an enclave can push additional data onto the
+ * stack (and modify RSP) to pass information to the optional user handler (see
+ * below).
+ *
+ * Most exceptions reported on ENCLU, including those that occur within the
+ * enclave, are fixed up and reported synchronously instead of being delivered
+ * via a standard signal. Debug Exceptions (#DB) and Breakpoints (#BP) are
+ * never fixed up and are always delivered via standard signals. On synchronously
+ * reported exceptions, -EFAULT is returned and details about the exception are
+ * recorded in @run.exception, the optional sgx_enclave_exception struct.
+ *
+ * Return:
+ * - 0:		ENCLU function was successfully executed.
+ * - -EINVAL:	Invalid ENCL number (neither EENTER nor ERESUME).

+ * UC_SIGCONTEXT_SS will correctly restore at least the low 32 bits of esp
+ * regardless of SS (i.e. they implement espfix).
+ *
+ * Kernels that set UC_SIGCONTEXT_SS will also set UC_STRICT_RESTORE_SS
+ * when delivering a signal that came from 64-bit code.
+ *
+ * Sigreturn restores SS as follows:
+ *
+ * if (saved SS is valid || UC_STRICT_RESTORE_SS is set ||
+ *     saved CS is not 64-bit)
+ *         new SS = saved SS  (will fail IRET and signal if invalid)
+ * else
+ *         new SS = a flat 32-bit data segment
+ *
+ * This behavior serves three purposes:
+ *
+ * - Legacy programs that construct a 64-bit sigcontext from scratch
+ *   with zero or garbage in the SS slot (e.g. old CRIU) and call
+ *   sigreturn will still work.
+ *
+ * - Old DOSEMU versions sometimes catch a signal from a segmented
+ *   context, delete the old SS segment (with modify_ldt), and change
+ *   the saved CS to a 64-bit segment.  These DOSEMU versions expect
+ *   sigreturn to send them back to 64-bit mode without killing them,
+ *   despite the fact that the SS selector when the signal was raised is
+ *   no longer valid.  UC_STRICT_RESTORE_SS will be clear, so the kernel
+ *   will fix up SS for these DOSEMU versions.
+ *
+ * - Old and new programs that catch a signal and return without
+ *   modifying the saved context will end up in exactly the state they
+ *   started in, even if they were running in a segmented context when
+ *   the signal was raised..  Old kernels would lose track of the
+ *   previous SS value.

+/* 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.
+ *
+ * SYS_SYSCALL_ENTRYPOINT:
+ *   Some applications (such as sandboxes that filter system calls), need
+ *   to be able to run custom-code each time a system call is made. If this
+ *   macro is defined, it expands to the name of a "common" symbol. If
+ *   this symbol is assigned a non-NULL pointer value, it is used as the
+ *   address of the system call entrypoint.
+ *   A pointer to this symbol can be obtained by calling
+ *   get_syscall_entrypoint()
+ *
+ * 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.

+/* 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.
