      parisc: Replace PT_NLEVELS with CONFIG_PGTABLE_LEVELS · c19edb69
      Guenter Roeck authored
      The following warning is seen when compiling parisc images
      
      ./arch/parisc/include/asm/pgalloc.h: In function 'pgd_alloc':
      ./arch/parisc/include/asm/pgalloc.h:29:5: warning: "PT_NLEVELS" is not defined
      
      Some definitions of PT_NLEVELS were missed with the conversion to
      CONFIG_PGTABLE_LEVELS.
      
      Fixes: f24ffde4 ("parisc: expose number of page table levels

      parisc: Eliminate sg_virt_addr() and private scatterlist.h · 8bf8a1d1
      Matthew Wilcox authored
      The only reason to keep parisc's private asm/scatterlist.h was that it
      had the macro sg_virt_addr().  Convert all callers to use something else
      (sometimes just sg->offset was enough, others should use sg_virt()), and
      we can just use the asm-generic scatterlist.h instead.

      media: remove unused variable that causes a warning · 1d11437f
      Linus Torvalds authored
      My 'allmodconfig' build is _almost_ free of warnings, and most of the
      remaining ones are for legacy drivers that just do bad things that I
      can't find it in my black heart to care too much about.  But this one
      was just annoying me:
      
         drivers/media/v4l2-core/videobuf2-core.c:3256:26: warning: unused variable ‘fileio’ [-Wunused-variable]
      
      because commit 0e661006 ("[media] vb2: fix 'UNBALANCED' warnings
      when calling vb2_thread_stop()") removed all users of 'fileio' and
      instead calls "__vb2_cleanup_fileio(q)" to clean up q->fileio.  But the
      now unused 'fileio' variable was left around.

        It was delayed for a bit due to some questions surrounding some of the

        one tiny regression for people who were previously putting multiple

        odd reason, but Peter is working on fixing that.  If not, I'll send a
        revert for the offending patch, but I have faith that Peter can
        address it.
      
        Other than the console work here, there's the usual serial driver
        updates and changes, and a buch of 8250 reworks to try to make that
        driver easier to maintain over time, and have it support more devices

      Revert "ocfs2: incorrect check for debugfs returns" · 8f443e23
      Linus Torvalds authored
      This reverts commit e2ac55b6.
      
      Huang Ying reports that this causes a hang at boot with debugfs disabled.
      
      It is true that the debugfs error checks are kind of confusing, and this
      code certainly merits more cleanup and thinking about it, but there's
      something wrong with the trivial "check not just for NULL, but for error
      pointers too" patch.
      
      Yes, with debugfs disabled, we will end up setting the o2hb_debug_dir
      pointer variable to an error pointer (-ENODEV), and then continue as if
      everything was fine.  But since debugfs is disabled, all the _users_ of
      that pointer end up being compiled away, so even though the pointer can
      not be dereferenced, that's still fine.
      
      So it's confusing and somewhat questionable, but the "more correct"
      error checks end up causing more trouble than they fix.

      example, if the touchpad x resolution is 2800 and x trace number is 20,

      smp: don't use 16-bit words for atomic accesses · f4d03bd1
      Linus Torvalds authored
      Yes, it should work, but it's a bad idea.  Not only did ARM64 not have
      the 16-bit access code (there's a separate patch to add it), it's just
      not a good atomic type.  Some architectures fundamentally don't do
      atomic accesses in them (alpha), and it's not like it saves any space
      here anyway because of structure packing issues.
      
      We normally should aim for flags to be "unsigned int" or "unsigned
      long".  And if space is at a premium, use a single byte (although that
      causes problems on alpha again).  There might be very special cases
      where a 16-byte entity is really wanted, but this is not one of them.

      hexdump: avoid warning in test function · 17974c05
      Linus Torvalds authored
      The test_data_1_le[] array is a const array of const char *.  To avoid
      dropping any const information, we need to use "const char * const *",
      not just "const char **".
      
      I'm not sure why the different test arrays end up having different
      const'ness, but let's make the pointer we use to traverse them as const
      as possible, since we modify neither the array of pointers _or_ the
      pointers we find in the array.

      fs: take i_mutex during prepare_binprm for set[ug]id executables · 8b01fc86
      Jann Horn authored
      This prevents a race between chown() and execve(), where chowning a
      setuid-user binary to root would momentarily make the binary setuid
      root.
      
      This patch was mostly written by Linus Torvalds.

      smp: Fix error case handling in smp_call_function_*() · 5224b961
      Linus Torvalds authored
      Commit 8053871d ("smp: Fix smp_call_function_single_async()
      locking") fixed the locking for the asynchronous smp-call case, but in
      the process of moving the lock handling around, one of the error cases
      ended up not unlocking the call data at all.
      
      This went unnoticed on x86, because this is a "caller is buggy" case,
      where the caller is trying to call a non-existent CPU.  But apparently
      ARM does that (at least under qemu-arm).  Bindly doing cross-cpu calls
      to random CPU's that aren't even online seems a bit fishy, but the error
      handling was clearly not correct.
      
      Simply add the missing "csd_unlock()" to the error path.
