      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      Greg Kroah-Hartman authored
      Many source files in the tree are missing licensing information, which
      makes it harder for compliance tools to determine the correct license.
      
      By default all files without license information are under the default
      license of the kernel, which is GPL version 2.
      
      Update the files which contain no license information with the 'GPL-2.0'
      SPDX license identifier.  The SPDX identifier is a legally binding
      shorthand, which can be used instead of the full boiler plate text.
      
      This patch is based on work done by Thomas Gleixner and Kate Stewart and
      Philippe Ombredanne.
      
      How this work was done:
      
      Patches were generated and checked against linux-4.14-rc6 for a subset of
      the use cases:
       - file had no licensing information it it.
       - file was a */uapi/* one with no licensing information in it,
       - file was a */uapi/* one with existing licensing information,
      
      Further patches will be generated in subsequent months to fix up cases
      where non-standard...

      m68k: switch to generic sys_execve()/kernel_execve() · d878d6da
      Al Viro authored
      
      
      The tricky part here is that task_pt_regs() on m68k works *only* for
      process inside do_signal().  However, we need something much simpler -
      pt_regs of a process inside do_signal() may be at different offsets
      from the stack bottom, depending on the way we'd entered the kernel,
      but for a task inside sys_execve() it *is* at constant offset.
      Moreover, for a kernel thread about to become a userland process the
      same location is also fine - setting sp to that will leave the kernel
      stack pointer at the very bottom of the kernel stack when we finally
      switch to userland.

      m68k: merge the mmu and non-mmu versions of sys_m68k.c · cae2e6cc
      Greg Ungerer authored
      
      
      There is a lot of common code in the sys_m68k.c files. The mmu and non-mmu
      versions can easily be merged into a single file.
      
      There is really only 2 functions that differ in the 2 cases. A single
      ifdef on CONFIG_MMU can take care of this. Alternatively we could break
      those 2 functions out and maintain sys_m68k_no.c and sys_m68k_mm.c with
      just this code in it (Makefile could then just build the right one).
      Does anyone have strong feelings on which way they want this done?

      m68k: merge m68k and m68knommu arch directories · 66d857b0
      Greg Ungerer authored
      
      
      There is a lot of common code that could be shared between the m68k
      and m68knommu arch branches. It makes sense to merge the two branches
      into a single directory structure so that we can more easily share
      that common code.
      
      This is a brute force merge, based on a script from Stephen King
      <sfking@fdwdc.com>, which was originally written by Arnd Bergmann
      <arnd@arndb.de>.
      
      > The script was inspired by the script Sam Ravnborg used to merge the
      > includes from m68knommu. For those files common to both arches but
      > differing in content, the m68k version of the file is renamed to
      > <file>_mm.<ext> and the m68knommu version of the file is moved into the
      > corresponding m68k directory and renamed <file>_no.<ext> and a small
      > wrapper file <file>.<ext> is used to select between the two version. Files
      > that are common to both but don't differ are removed from the m68knommu
      > tree and files and directories that are unique to the m68knommu tree are
      > moved to the m68k tree. Finally, the arch/m68knommu tree is removed.
      >
      > To select between the the versions of the files, the wrapper uses
      >
      > #ifdef CONFIG_MMU
      > #include <file>_mm.<ext>
      > #else
      > #include <file>_no.<ext>
      > #endif
      
      On top of this file merge I have done a simplistic merge of m68k and
      m68knommu Kconfig, which primarily attempts to keep existing options and
      menus in place. Other than a handful of options being moved it produces
      identical .config outputs on m68k and m68knommu targets I tested it on.
      
      With this in place there is now quite a bit of scope for merge cleanups
      in future patches.

      Make do_execve() take a const filename pointer · d7627467
      David Howells authored
      
      
      Make do_execve() take a const filename pointer so that kernel_execve() compiles
      correctly on ARM:
      
      arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type
      
      This also requires the argv and envp arguments to be consted twice, once for
      the pointer array and once for the strings the array points to.  This is
      because do_execve() passes a pointer to the filename (now const) to
      copy_strings_kernel().  A simpler alternative would be to cast the filename
      pointer in do_execve() when it's passed to copy_strings_kernel().
      
      do_execve() may not change any of the strings it is passed as part of the argv
      or envp lists as they are some of them in .rodata, so marking these strings as
      const should be fine.
      
      Further kernel_execve() and sys_execve() need to be changed to match.
      
      This has been test built on x86_64, frv, arm and mips.

      m68k: Add NPTL support · 9674cdc7
      Maxim Kuvyrkov authored
      
      
      This patch adds several syscalls, that provide necessary
      functionality to support NPTL on m68k/ColdFire.
      The syscalls are get_thread_area, set_thread_area, atomic_cmpxchg_32 and
      atomic_barrier.
      The cmpxchg syscall is required for ColdFire as it doesn't support 'cas'
      instruction.
      
      Also a ptrace call PTRACE_GET_THREAD_AREA is added to allow debugger to
      inspect the TLS storage.

      unified (weak) sys_pipe implementation · d35c7b0e
      Ulrich Drepper authored
      
      
      This replaces the duplicated arch-specific versions of "sys_pipe()" with
      one unified implementation.  This removes almost 250 lines of duplicated
      code.
      
      It's marked __weak, so that *if* an architecture wants to override the
      default implementation it can do so by simply having its own replacement
      version, since many architectures use alternate calling conventions for
      the 'pipe()' system call for legacy reasons (ie traditional UNIX
      implementations often return the two file descriptors in registers)
      
      I still haven't changed the cris version even though Linus says the BKL
      isn't needed.  The arch maintainer can easily do it if there are really
      no obstacles.

      Remove fs.h from mm.h · 4e950f6f
      Alexey Dobriyan authored
      
      
      Remove fs.h from mm.h. For this,
       1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
       2) Add back fs.h or less bloated headers (err.h) to files that need it.
      
      As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
      rebuilt down to 3444 (-12.3%).

      [PATCH] provide kernel_execve on all architectures · fe74290d
      Arnd Bergmann authored
      
      
      This adds the new kernel_execve function on all architectures that were using
      _syscall3() to implement execve.
      
      The implementation uses code from the _syscall3 macros provided in the
      unistd.h header file.  I don't have cross-compilers for any of these
      architectures, so the patch is untested with the exception of i386.
      
      Most architectures can probably implement this in a nicer way in assembly or
      by combining it with the sys_execve implementation itself, but this should do
      it for now.

      3.2GB when imported into git - space that would just make the early
