      PCI: Change all drivers to use pci_device->revision · 44c10138
      Auke Kok 提交于
      Instead of all drivers reading pci config space to get the revision
      ID, they can now use the pci_device->revision member.
      
      This exposes some issues where drivers where reading a word or a dword
      for the revision number, and adding useless error-handling around the
      read. Some drivers even just read it for no purpose of all.
      
      In devices where the revision ID is being copied over and used in what
      appears to be the equivalent of hotpath, I have left the copy code
      and the cached copy as not to influence the driver's performance.
      
      Compile tested with make all{yes,mod}config on x86_64 and i386.

      [PATCH] clocksource init adjustments (fix bug #7426) · 6bb74df4
      john stultz 提交于
      This patch resolves the issue found here:
      http://bugme.osdl.org/show_bug.cgi?id=7426
      
      The basic summary is:
      Currently we register most of i386/x86_64 clocksources at module_init
      time. Then we enable clocksource selection at late_initcall time. This
      causes some problems for drivers that use gettimeofday for init
      calibration routines (specifically the es1968 driver in this case),
      where durring module_init, the only clocksource available is the low-res
      jiffies clocksource. This may cause slight calibration errors, due to
      the small sampling time used.
      
      It should be noted that drivers that require fine grained time may not
      function on architectures that do not have better then jiffies
      resolution timekeeping (there are a few). However, this does not
      discount the reasonable need for such fine-grained timekeeping at init
      time.
      
      Thus the solution here is to register clocksources earlier (ideally when
      the hardware is being initialized), and then we enable clocksource
      selection at fs_initcall (before device_initcall).
      
      This patch should probably get some testing time in -mm, since
      clocksource selection is one of the most important issues for correct
      timekeeping, and I've only been able to test this on a few of my own
      boxes.
