      serial: Kill off NO_IRQ · d4e33fac
      Alan Cox authored
      We transform the offenders into a test of irq <= 0 which will be ok while
      the ARM people get their platform sorted. Once that is done (or in a while
      if they don't do it anyway) then we will change them all to !irq checks.
      
      For arch specific drivers that are already using NO_IRQ = 0 we just test
      against zero so we don't need to re-review them later.

      tty: rework pty count limiting · e9aba515
      Konstantin Khlebnikov authored
      After adding devpts multiple-insrances sysctl kernel.pty.max limit pty count for
      each devpts instance independently, while kernel.pty.nr shows total pty count.
      
      This patch restores sysctl kernel.pty.max as global limit (4096 by default),
      adds pty reseve for main devpts (mounted without "newinstance" argument),
      and new sysctl to tune it: kernel.pty.reserve (1024 by default)
      
      Also it adds devpts mount option "max=%d" to limit pty count for each devpts
      instance independently. (by default NR_UNIX98_PTY_MAX == 2^20)
      
      Thus devpts instances in containers cannot eat up all available pty even if we didn't
      set any limits, while with "max" argument we can adjust limits more precisely.
      
      Plus, now open("/dev/ptmx") return -ENOSPC in case lack of pty indexes,
      this is more informative than -EIO.

      tty: cleanup prohibition of direct opening for unix98 pty master · 593a27c4

      cleanup hack added in v2.6.27-3203-g15582d36
      
      comment from that patch:
      
      : pty: If the administrator creates a device for a ptmx slave we should not error
      :
      : The open path for ptmx slaves is via the ptmx device. Opening them any
      : other way is not allowed. Vegard Nossum found that previously this was not

      devpts_get_tty() returns non-null only for inodes on devpts, but there is no
      inodes for master-devices, /dev/ptmx (/dev/pts/ptmx) is the only way to open them.
      Thus we can completely forbid lookup for master-devices and eliminate that hack in
      tty_init_dev() because tty_open() will get EIO from tty_driver_lookup_tty().

      tpm: fix (ACPI S3) suspend regression · be405411
      Stefan Berger authored
      This patch fixes an (ACPI S3) suspend regression introduced in commit
      68d6e671 ("tpm: Introduce function to poll for result of self test")
      and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
      active.
      
      The suspend problem occurred if the TPM was disabled and/or deactivated
      and therefore the TPM_PCRRead checking the result of the (asynchronous)
      self test returned an error code which then caused the tpm_tis driver to
      become inactive and this then seemed to have negatively influenced the
      suspend support by the tpm_infineon driver...  Besides that the tpm_tis
      drive may stay active even if the TPM is disabled and/or deactivated.

      The type of 'make_request_fn' changed in 5a7bbad2 ("block: remove

      Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
      enabled.  However, kdump only enables one CPU in the new environment,
      thus causing tg3 to abort MSI-X setup.  When the driver attempts to
      enable INTA or MSI interrupt modes on a kdump kernel, interrupt
      delivery fails.
      
      This patch attempts to workaround the problem by forcing the driver
      to enable a single MSI-X interrupt.  In such a configuration, the
      device's multivector interrupt mode must be disabled.
