      ARM: imx: set up pllv3 POWER and BYPASS sequentially · 43c9b9e8
      Shawn Guo authored
      Currently, POWER and BYPASS bits are set up in a single write to pllv3
      register.  This causes problem occasionally from the IPU/HDMI testing.
      Let's follow FSL BSP code to set up POWER bit, relock, and then BYPASS
      sequentially.

      ARM: imx: pllv3 needs relock in .set_rate() call · bc3b84da
      Shawn Guo authored
      The pllv3 nees relock not only when powering up but also when rate
      changes.  The patch creates a helper function clk_pllv3_wait_lock() and
      moves the relock code from clk_pllv3_prepare() into there, so that
      both .prepare() and .set_rate() hooks of pllv3 can call into the helper
      for relocking.
      
      Since relock is only needed when PLL is powered up while clk_set_rate()
      could be called before clk is prepared, we need to add a check in
      clk_pllv3_wait_lock() to skip the relock if PLL is not powered.

      ARM: imx: add sleep for pllv3 relock · 322503a1
      Shawn Guo authored
      The pllv3 relock time varies in the range of 50us ~ 500us, depending on
      the specific PLL type, e.g. 50us for ARM PLL and 450us for Audio/Video
      PLL.  Let's add a usleep_range() call instead of doing busy wait during
      relock.

      ARM: imx: v7_cpu_resume() is needed by imx6sl build · 5d482172
      Shawn Guo authored
      Building a kernel with the following options,
      
        CONFIG_SMP=n
        CONFIG_PM=y
        CONFIG_SOC_IMX6SL=y
        CONFIG_SOC_IMX6Q=n
      
      we will see the build error below.
      
        arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':

        make[1]: *** [vmlinux] Error 1
      
      This is because that v7_cpu_resume() implemented in headsmp.S is also
      needed by imx6sl build.  Let's build headsmp.S for CONFIG_SOC_IMX6SL as
      well.

      ARM: imx: improve mxc_restart() on the SRC bit writes · 2c11b57a
      Shawn Guo authored
      The current comment in the code does not make it clear why the double writes
      on SRC bit is needed.  Let's quote the errata to get it clear.  Also, to
      ensure there are at least 2 writes happen in the same one 32kHz period,
      we actually need 3 writes.  Let's add the third one.

      ARM: imx: remove imx_src_prepare_restart() call · b6e23bb6
      Shawn Guo authored
      There is ~10% possibility that the following emergency restart command
      fails to reboot imx6q.
      
      $ echo b > /proc/sysrq-trigger
      
      The IMX restart routine mxc_restart() assumes that it will always run on
      primary core, and will call imx_src_prepare_restart() to disable
      secondary cores in order to get them come to online in the following
      boot.  However, the assumption is only true for normal kernel_restart()
      case where migrate_to_reboot_cpu() will be called to migrate to primary
      core, but not necessarily true for emergency_restart() case.  So when
      emergency_restart() calls into mxc_restart() on any secondary core,
      system will hang immediately once imx_src_prepare_restart() is called
      to disabled secondary cores.  Since emergency_restart() is defined as a
      function that is safe to call in interrupt context, we cannot just call
      migrate_to_reboot_cpu() to fix the issue.
      
      Fortunately, we just found that the issue can be fixed at imx6q platform
      level.  We used to call imx_src_prepare_restart() to disable all
      secondary cores before resetting hardware.  Otherwise, the secondary
      will fail come to online in the reboot.  However, we recently found that
      after commit 6050d181 (ARM: imx: reset core along with enable/disable
      operation) comes to play, we do not need to reset the secondary cores
      any more.  That said, mxc_restart() now can run on any core to reboot
      the system, as long as we remove the imx_src_prepare_restart() call from
      mxc_restart().
      
      So let's simply remove imx_src_prepare_restart() call to fix the above
      emergency restart failure.

      Pull ARM SoC cleanups from Olof Johansson:
       "This branch contains code cleanups, moves and removals for 3.13.
      
        Qualcomm msm targets had a bunch of code removal for legacy non-DT
        platforms.  Nomadik saw more device tree conversions and cleanup of
        old code.  Tegra has some code refactoring, etc.
      
        One longish patch series from Sebastian Hasselbarth changes the
        init_time hooks and tries to use a generic implementation for most
        platforms, since they were all doing more or less the same things.
      
        Finally the "shark" platform is removed in this release.  It's been
        abandoned for a while and nobody seems to care enough to keep it
        around.  If someone comes along and wants to resurrect it, the removal
        can easily be reverted and code brought back.
      
        Beyond this, mostly a bunch of removals of stale content across the
        board, etc"

       "Dave Jones's trinity program was able to enable the function tracer

        When I was able to reproduce it with trinity, I was able to track down

        I discovered that the check for whether the function tracepoint should

        by default, lets the user continue.  The user should not by default be
        able to enable function tracing.
      
        The fix is to use "perf_paranoid_tracepoint_raw()" which will not let
        the user enable function tracing.  This is a security fix as normal

      parisc: sticon - unbreak on 64bit kernel · 0219132f
      Helge Deller authored
      STI text console (sticon) was broken on 64bit machines with more than
      4GB RAM and this lead in some cases to a kernel crash.
      
      Since sticon uses the 32bit STI API it needs to keep pointers to memory
      below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel
      stack) might be above 4GB which then may crash the kernel in the STI
      functions.
      
      Additionally sticon didn't selected the built-in framebuffer fonts by
      default. This is now fixed.
      
      On a side-note: Theoretically we could enhance the sticon driver to
      use the 64bit STI API. But - beside the fact that some machines don't
      provide a 64bit STI ROM - this would just add complexity.

      always return correct errno failure codes to userspace.
      
      Problem showed up during 32bit userspace tests in which writev() used a

      Install targets (install, zinstall, uinstall) on parisc have a

      parisc: provide macro to create exception table entries · 61dbbaeb
      Helge Deller authored
      Provide a macro ASM_EXCEPTIONTABLE_ENTRY() to create exception table
      entries and convert all open-coded places to use that macro.
      
      This patch is a first step toward creating a exception table which only
      holds 32bit pointers even on a 64bit kernel. That way in my own kernel
      I was able to reduce the in-kernel exception table from 44kB to 22kB.

      Pull CIFS updates from Steve French:
       "Includes a couple of fixes, plus changes to make multiplex identifiers
        easier to read and correlate with network traces, and a set of
        enhancements for SMB3 dialect.  Also adds support for per-file
        compression for both cifs and smb2/smb3 ("chattr +c filename).
      
        Should have at least one other merge request ready by next week with
        some new SMB3 security features and copy offload support"
      
      * 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
        Query network adapter info at mount time for debugging
        Fix unused variable warning when CIFS POSIX disabled
        Allow setting per-file compression via CIFS protocol
        Query File System Alignment
        Query device characteristics at mount time from server on SMB2/3 not just on cifs mounts
        cifs: Send a logoff request before removing a smb session
        cifs: Make big endian multiplex ID sequences monotonic on the wire
        cifs: Remove redundant multiplex identifier check from check_smb_hdr()

      ARM64: /proc/interrupts: display IPIs of online CPUs only · 67317c26
      Sudeep KarkadaNagesha authored
      The non-IPI interrupts are displayed only for the online cpus from
      show_interrupts in kernel/irq/proc.c before calling arch_show_interrupts().
      As a result, the column headers and the IPI count don't match if any
      CPU is offline.
      
      This patch fixes show_ipi_list to display IPIs for online CPUs only.
