      kconfig: Check for libncurses before menuconfig · ff85a1a8
      Borislav Petkov authored
      There is a check and a nice user-friendly message when the curses
      library is not present on the system and the user wants to do "make
      menuconfig". It doesn't get issued, though. Instead, we fail the build
      when mconf.c doesn't find the curses.h header:
      
          HOSTCC  scripts/kconfig/mconf.o
        In file included from scripts/kconfig/mconf.c:23:0:
        scripts/kconfig/lxdialog/dialog.h:38:20: fatal error: curses.h: No such file or directory
         #include CURSES_LOC
                            ^
        compilation terminated.
      
      Make that check a prerequisite to mconf so that the user sees the error
      message instead:
      
        $ make menuconfig
         *** Unable to find the ncurses libraries or the

      x86: fix 32-bit case of __get_user_asm_u64() · 33c9e972
      Linus Torvalds authored
      The code to fetch a 64-bit value from user space was entirely buggered,
      and has been since the code was merged in early 2016 in commit
      b2f68038 ("x86/mm/32: Add support for 64-bit __get_user() on 32-bit
      kernels").
      
      Happily the buggered routine is almost certainly entirely unused, since
      the normal way to access user space memory is just with the non-inlined
      "get_user()", and the inlined version didn't even historically exist.
      
      The normal "get_user()" case is handled by external hand-written asm in
      arch/x86/lib/getuser.S that doesn't have either of these issues.
      
      There were two independent bugs in __get_user_asm_u64():
      
       - it still did the STAC/CLAC user space access marking, even though
         that is now done by the wrapper macros, see commit 11f1a4b9
         ("x86: reorganize SMAP handling in user space accesses").
      
         This didn't result in a semantic error, it just means that the
         inlined optimized version was hugely less efficient than the
         allegedly slower standard version, since the CLAC/STAC overhead is
         quite high on modern Intel CPU's.
      
       - the double register %eax/%edx was marked as an output, but the %eax
         part of it was touched early in the asm, and could thus clobber other
         inputs to the asm that gcc didn't expect it to touch.
      
         In particular, that meant that the generated code could look like
         this:
      
              mov    (%eax),%eax
              mov    0x4(%eax),%edx
      
         where the load of %edx obviously was _supposed_ to be from the 32-bit
         word that followed the source of %eax, but because %eax was
         overwritten by the first instruction, the source of %edx was
         basically random garbage.
      
      The fixes are trivial: remove the extraneous STAC/CLAC entries, and mark
      the 64-bit output as early-clobber to let gcc know that no inputs should
      alias with the output register.

      Clean up x86 unsafe_get/put_user() type handling · 334a023e
      Linus Torvalds authored
      Al noticed that unsafe_put_user() had type problems, and fixed them in
      commit a7cc722f ("fix unsafe_put_user()"), which made me look more
      at those functions.
      
      It turns out that unsafe_get_user() had a type issue too: it limited the
      largest size of the type it could handle to "unsigned long".  Which is
      fine with the current users, but doesn't match our existing normal
      get_user() semantics, which can also handle "u64" even when that does
      not fit in a long.
      
      While at it, also clean up the type cast in unsafe_put_user().  We
      actually want to just make it an assignment to the expected type of the
      pointer, because we actually do want warnings from types that don't
      convert silently.  And it makes the code more readable by not having
      that one very long and complex line.
      
      [ This patch might become stable material if we ever end up back-porting
        any new users of the unsafe uaccess code, but as things stand now this
        doesn't matter for any current existing uses. ]

      Rather than waiting for reset work thread to stop queues and abort the ios,
      immediately stop the queues on error detection. Reset thread will restop
      the queues (as it's called on other paths), but it does not appear to have

      Linus Torvalds authored
      Pull ARM SoC fixes from Olof Johansson:
       "We had a small batch of fixes before -rc1, but here is a larger one.
        It contains a backmerge of 4.12-rc1 since some of the downstream
        branches we merge had that as base; at the same time we already had
        merged contents before -rc1 and rebase wasn't the right solution.
      
        A mix of random smaller fixes and a few things worth pointing out:
      
         - We've started telling people to avoid cross-tree shared branches if
           all they're doing is picking up one or two DT-used constants from a
           shared include file, and instead to use the numeric values on first
           submission. Follow-up moving over to symbolic names are sent in
           right after -rc1, i.e. here. It's only a few minor patches of this
           type.
      
         - Linus Walleij and others are resurrecting the 'Gemini' platform,
           and wanted a cut-down platform-specific defconfig for it. So I
           picked that up for them.
      
         - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
           helps people to prepare patches since it's a pain when defconfig
           and current savedefconfig contents differs too much.
      
         - Devicetree additions for some pinctrl drivers for Armada that were
           merged this window. I'd have preferred to see those earlier but
           it's not a huge deail.
      
        The biggest change worth pointing out though since it's touching other
        parts of the tree: We added prefixes to be used when cross-including
        DT contents between arm64 and arm, allowing someone to #include
        <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
        arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
        resulted in a recursive symlink.
      
        Instead, I've now moved it out of arch/*/boot/dts/include, into a
        shared location under scripts/dtc. While I was at it, I consolidated
        so all architectures now behave the same way in this manner.
      
        Rob Herring (DT maintainer) has acked it. I cc:d most other arch
        maintainers but nobody seems to care much; it doesn't really affect
        them since functionality is unchanged for them by default"
