Pull x86 entry code related updates from Thomas Gleixner: - Consolidate the macros for .byte ... opcode sequences - Deduplicate register offset defines in include files - Simplify the ia32,x32 compat handling of the related syscall tables to get rid of #ifdeffery. - Clear all EFLAGS which are not required for syscall handling - Consolidate the syscall tables and switch the generation over to the generic shell script and remove the CFLAGS tweaks which are not longer required. - Use 'int' type for system call numbers to match the generic code. - Add more selftests for syscalls * tag 'x86-entry-2021-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/syscalls: Don't adjust CFLAGS for syscall tables x86/syscalls: Remove -Wno-override-init for syscall tables x86/uml/syscalls: Remove array index from syscall initializers x86/syscalls: Clear 'offset' and 'prefix' in case they are set in env x86/entry: Use int everywhere for system call numbers x86/entry: Treat out of range and gap system calls the same x86/entry/64: Sign-extend system calls on entry to int selftests/x86/syscall: Add tests under ptrace to syscall_numbering_64 selftests/x86/syscall: Simplify message reporting in syscall_numbering selftests/x86/syscall: Update and extend syscall_numbering_64 x86/syscalls: Switch to generic syscallhdr.sh x86/syscalls: Use __NR_syscalls instead of __NR_syscall_max x86/unistd: Define X32_NR_syscalls only for 64-bit kernel x86/syscalls: Stop filling syscall arrays with *_sys_ni_syscall x86/syscalls: Switch to generic syscalltbl.sh x86/entry/x32: Rename __x32_compat_sys_* to __x64_compat_sys_*
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
