      tpm_tis: Fix the probing for interrupts · a7b66822
      Stefan Berger 提交于
      This patch fixes several aspects of the probing for interrupts.
      
      This patch reads the TPM's timeouts before probing for the interrupts. The
      tpm_get_timeouts() function is invoked in polling mode and gets the proper
      timeouts from the TPM so that we don't need to fall back to 2 minutes timeouts
      for short duration commands while the interrupt probing is happening.
      
      This patch introduces a variable probed_irq into the vendor structure that gets
      the irq number if an interrupt is received while the the tpm_gen_interrupt()
      function is run in polling mode during interrupt probing. Previously some
      parts of tpm_gen_interrupt() were run in polling mode, then the irq variable
      was set in the interrupt handler when an interrupt was received and execution
      of tpm_gen_interrupt() ended up switching over to interrupt mode.
      tpm_gen_interrupt() execution ended up on an event queue where it eventually
      timed out since the probing handler doesn't wake any queues.
      
      Before calling into free_irq() clear all interrupt flags that may have
      been set by the TPM. The reason is that free_irq() will call into the probing
      interrupt handler and may otherwise fool us into thinking that a real interrupt
      happened (because we see the flags as being set) while the TPM's interrupt line
      is not even connected to anything on the motherboard. This solves a problem
      on one machine I did testing on (Thinkpad T60).
      
      If a TPM claims to use a specifc interrupt, the probing is done as well
      to verify that the interrupt is actually working. If a TPM indicates
      that it does not use a specific interrupt (returns '0'), probe all interrupts
      from 3 to 15.

      tpm_tis: Add timeouts sysfs entry · 62592101
      Stefan Berger 提交于
      Display the TPM's interface timeouts in a 'timeouts' sysfs entry. Display
      the entries as having been adjusted when they were scaled due to their values
      being reported in milliseconds rather than microseconds.

      Revert "tpm_tis: Use timeouts returned from TPM" · e5871372
      Linus Torvalds 提交于
      This reverts commit 9b29050f.
      
      It has caused hibernate regressions, for example Juri Sladby's report:
      
        "I'm unable to hibernate 2.6.37.1 unless I rmmod tpm_tis:
         [10974.074587] Suspending console(s) (use no_console_suspend to debug)
         [10974.103073] tpm_tis 00:0c: Operation Timed out
         [10974.103089] legacy_suspend(): pnp_bus_suspend+0x0/0xa0 returns -62
         [10974.103095] PM: Device 00:0c failed to freeze: error -62"
      
      and Rafael points out that some of the new conditionals in that commit
      seem to make no sense.  This commit needs more work and testing, let's
      revert it for now.

      PCI: Cleanup the includes of <linux/pci.h> · 6473d160
      Jean Delvare 提交于
      I noticed that many source files include <linux/pci.h> while they do
      not appear to need it. Here is an attempt to clean it all up.
      
      In order to find all possibly affected files, I searched for all
      files including <linux/pci.h> but without any other occurence of "pci"
      or "PCI". I removed the include statement from all of these, then I
      compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
      false positives manually.
      
      My tests covered 66% of the affected files, so there could be false
      positives remaining. Untested files are:

      sound/oss/au1550_ac97.c
      
      I would welcome test reports for these files. I am fine with removing
      the untested files from the patch if the general opinion is that these
      changes aren't safe. The tested part would still be nice to have.
      
      Note that this patch depends on another header fixup patch I submitted
      to LKML yesterday:
