      vfs: Deduplicate code shared by xattr system calls operating on paths · 8cc43116
      Eric Biggers authored
      The following pairs of system calls dealing with extended attributes only
      differ in their behavior on whether the symbolic link is followed (when
      the named file is a symbolic link):
      
      - setxattr() and lsetxattr()
      - getxattr() and lgetxattr()
      - listxattr() and llistxattr()
      - removexattr() and lremovexattr()
      
      Despite this, the implementations all had duplicated code, so this commit
      redirects each of the above pairs of system calls to a corresponding
      function to which different lookup flags (LOOKUP_FOLLOW or 0) are passed.
      
      For me this reduced the stripped size of xattr.o from 8824 to 8248 bytes.

      Pull parisc fix from Helge Deller:
       "This patch intentionally breaks the ABI on PARISC Linux!
      
        It assigns new numbers to SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS so
        that those are below 32 and thus leaves us with 32 RT signals like
        other Linux architectures (SIGRTMIN now becomes 32 instead of 37).
      
        Even if it breaks the ABI, it doesn't seem to have any visible impact
        on existing userspace applications.  I was able to mix new kernel
        and/or glibc without impacting normal bootup.  So, even if it breaks
        the ABI, the benefits (e.g.  being able to use systemd on PARISC
        Linux) outperforms the minimal (if any) impact it gives.
      
        The patch has been discussed on the parisc kernel mailing list and the
        coresponding glibc patch will be committed by the parisc glibc
        maintainer after this patch went into 3.18.

        reasons and excuses.

        that fairly unlikely anyway :^p    - Linus ]

       "This set has a few minor updates, but the big change is the redesign
        of the trampoline logic.
      
        The trampoline logic of 3.17 required a descriptor for every function
        that is registered to be traced and uses a trampoline.  Currently,
        only the function graph tracer uses a trampoline, but if you were to
        trace all 32,000 (give or take a few thousand) functions with the
        function graph tracer, it would create 32,000 descriptors to let us
        know that there's a trampoline associated with it.  This takes up a
        bit of memory when there's a better way to do it.
      
        The redesign now reuses the ftrace_ops' (what registers the function
        graph tracer) hash tables.  The hash tables tell ftrace what the
        tracer wants to trace or doesn't want to trace.  There's two of them:
        one that tells us what to trace, the other tells us what not to trace.
        If the first one is empty, it means all functions should be traced,
        otherwise only the ones that are listed should be.  The second hash
        table tells us what not to trace, and if it is empty, all functions
        may be traced, and if there's any listed, then those should not be
        traced even if they exist in the first hash table.
      
        It took a bit of massaging, but now these hashes can be used to keep
        track of what has a trampoline and what does not, and allows the
        ftrace accounting to work.  Now we can trace all functions when using
        the function graph trampoline, and avoid needing to create any special

      parisc: Reduce SIGRTMIN from 37 to 32 to behave like other Linux architectures · 1f25df2e
      Helge Deller authored
      This patch reduces the value of SIGRTMIN on PARISC from 37 to 32, thus
      increasing the number of available RT signals and bring it in sync with other
      Linux architectures.
      
      Historically we wanted to natively support HP-UX 32bit binaries with the
      PA-RISC Linux port.  Because of that we carried the various available signals
      from HP-UX (e.g. SIGEMT and SIGLOST) and folded them in between the native
      Linux signals.  Although this was the right decision at that time, this
      required us to increase SIGRTMIN to at least 37 which left us with 27 (64-37)
      RT signals.
      
      Those 27 RT signals haven't been a problem in the past, but with the upcoming
      importance of systemd we now got the problem that systemd alloctes (hardcoded)
      signals up to SIGRTMIN+29 which is beyond our NSIG of 64. Because of that we
      have not been able to use systemd on the PARISC Linux port yet.
      
      Of course we could ask the systemd developers to not use those hardcoded
      values, but this change is very unlikely, esp. with PA-RISC being a niche
      architecture.
      
      The other possibility would be to increase NSIG to e.g. 128, but this would
      mean to duplicate most of the existing Linux signal handling code into the
      parisc specific Linux kernel tree which would most likely introduce lots of new
      bugs beside the code duplication.
      
      The third option is to drop some HP-UX signals and shuffle some other signals
      around to bring SIGRTMIN to 32.  This is of course an ABI change, but testing
      has shown that existing Linux installations are not visibly affected by this
      change - most likely because we move those signals around which are rarely used
      and move them to slots which haven't been used in Linux yet. In an existing
      installation I was able to exchange either the Linux kernel or glibc (or both)
      without affecting the boot process and installed applications.
      
      Dropping the HP-UX signals isn't an issue either, since support for HP-UX was
      basically dropped a few months back with Kernel 3.14 in commit
      f5a408d5 already, when we changed EWOULDBLOCK
      to be equal to EAGAIN.
      
      So, even if this is an ABI change, it's better to change it now and thus bring
      PARISC Linux in sync with other architectures to avoid other issues in the
      future.

      Pull sound updates from Takashi Iwai:
       "This time it's a relatively calm update batch, but the amount isn't
        too small in the end.  Here we go over some highlights:
      
        ALSA core:
         - One major change is the support of nonatomic PCM operations.  This
           allows the trigger and other callbacks to call schedule(), which
           would be useful for mailbox type communications.  Already some
           drivers (Digigram ones) have been converted to use together with
           threaded irqs as an example.
         - Improvement / fixes of DSD PCM format support
      
        HD-audio:
         - Large volume of rewrites are found in Realtek codec driver for
           converting Dell and HP quirks to generic forms.
         - Inverted dmic code cleanup from David.
         - Realtek COEF access has been optimized.
         - Now HD-audio jack infrastructure allows multiple callbacks, which
           fixes / simplifies the jack-dependent power controls on STAC/IDT
           and VIA codecs.
         - Many additional device-specific fixups as usual
         - A few deadcode cleanups, CA0132 code cleanup, etc.
      
        ASoC:
         - More componentization work from Lars-Peter, this time mainly
           cleaning up the suspend and bias level transition callbacks.
         - Real system support for the Intel drivers and a bunch of fixes and
           enhancements for the associated CODEC drivers, this is going to
           need a lot quirks over time due to the lack of any firmware
           description of the boards.
         - Jack detect support for simple card from Dylan Reid.
         - A bunch of small fixes and enhancements for the Freescale drivers.
         - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
           Everest Semiconductor ES8328 and Freescale cards using the ASRC in
           newer i.MX processors.
         - A few simple-card fixes, mostly cleanups but also a fix for
           interaction between GPIO 0 and simple-card.
      
        Misc:
         - Virtuoso / Oxygen updates by Clemens
         - USB-audio: Yamaha MOTIF XF MIDI port name fixes
         - Conversion of kernel messages to standard dev_*() in ctxfi driver"

      sparc64: Fix lockdep warnings on reboot on Ultra-5 · bdcf81b6
      David S. Miller authored
      Inconsistently, the raw_* IRQ routines do not interact with and update
      the irqflags tracing and lockdep state, whereas the raw_* spinlock
      interfaces do.
      
      This causes problems in p1275_cmd_direct() because we disable hardirqs
      by hand using raw_local_irq_restore() and then do a raw_spin_lock()
      which triggers a lockdep trace because the CPU's hw IRQ state doesn't
      match IRQ tracing's internal software copy of that state.
      
      The CPU's irqs are disabled, yet current->hardirqs_enabled is true.
