      ALSA: ctxfi - Remove PAGE_SIZE limitation · cd391e20
      Takashi Iwai authored
      Remove the limitation of PAGE_SIZE to be 4k by defining the own
      page size and macros for 4k.  8kb page size could be natively supported,
      but it's disabled right now for simplicity.
      
      Also, clean up using upper_32_bits() macro.

      ALSA: ctxfi - Fix supported PCM formats · d2b9b96c
      Takashi Iwai authored
      The device seems supporting only U8, S16, S24_3LE, S32.  Other linear
      formats result in bad outputs.
      
      Also, added the support for 32bit float format, which wasn't listed
      in the original code.

      ALSA: ctxfi - Fix PCM device naming · 8372d498
      Takashi Iwai authored
      PCM names for surround streams should be also fixed as well as the mixer
      element names.  Also, a bit clean up for PCM name setup.

      Takashi Iwai authored
      We usually pick up "Surround" mixer for the rear output, and "Side"
      for the extra surround.  Fix the channel mapping to follow it.

      ALSA: ALSA: ctxfi - Release PCM resources at each prepare call · 822fa19b
      Takashi Iwai authored
      The prepare callback can be called multiple times, thus it needs to
      release and acquire the resource again by itself at the second or later
      call.
      
      Simply add pcm_release_resources() at the beginning of each prepare
      callback in ctatc.c.

      ALSA: ctxfi - Add depends on X86 · 3e3ee6dc
      Takashi Iwai authored
      The ctxfi driver requires explicitly the 4k page size, and gives a
      build error on architectures with non-4k pages.
      As a workaround, just add the kconfig dependency on X86, which is
      the only architecture ever tested.

      David Howells authored
      Don't check vm_region::vm_start is page aligned in add_nommu_region() because
      the region may reflect some non-page-aligned mapped file, such as could be
      obtained from RomFS XIP.

      random: make get_random_int() more random · 8a0a9bd4
      Linus Torvalds authored
      It's a really simple patch that basically just open-codes the current
      "secure_ip_id()" call, but when open-coding it we now use a _static_
      hashing area, so that it gets updated every time.
      
      And to make sure somebody can't just start from the same original seed of
      all-zeroes, and then do the "half_md4_transform()" over and over until
      they get the same sequence as the kernel has, each iteration also mixes in
      the same old "current->pid + jiffies" we used - so we should now have a
      regular strong pseudo-number generator, but we also have one that doesn't
      have a single seed.
      
      Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It
      has no real meaning. It could be anything. I just picked the previous
      seed, it's just that now we keep the state in between calls and that will
      feed into the next result, and that should make all the difference.
      
      I made that hash be a per-cpu data just to avoid cache-line ping-pong:
      having multiple CPU's write to the same data would be fine for randomness,
      and add yet another layer of chaos to it, but since get_random_int() is
      supposed to be a fast interface I did it that way instead. I considered
      using "__raw_get_cpu_var()" to avoid any preemption overhead while still
      getting the hash be _mostly_ ping-pong free, but in the end good taste won
      out.
