- Updated to 2.6.36-rc2:
  - SYSFS_DEPRECATED: enable deprecated sysfs features to support
                      old userspace tools
    - Disabled; defaults to n
    - Userspace tools should be updated. If they aren't by
      release time we can enable this.

- JUMP_LABEL: Optimize trace point call sites
    - With compiler support, allows trace points to be optimized
      out entirely until used
    - Enabled; defaults to n

- IRQ_TIME_ACCOUNTING: Fine granularity task level IRQ time accounting
    - Adds a timestamp during transitions between softirq and
      hardirq state
    - Disabled; defaults to n
    - There is a performance impact and its usefulness is
      questionable unless you're working on a driver.

- X86_RESERVE_LOW: Amount of low memory, in kilobytes, to reserve
                     for the BIOS
    - Reserve low memory for the BIOS; Some BIOSes can trash parts

    - Set to 64k; the default

- PM_OPP: Operating Performance Point (OPP) Layer library
    - Represents voltage domains for certain SoCs
    - Disabled; defaults to n
    - openSUSE isn't targetting x86-based SoCs so this is
      unnecessary

      - Enabled as m; defaults to n
      - PRETTYDEBUG: Include file:line in ceph debug output
        - Enabled; defaults to n
        - There aren't a lot of ceph users out there and since this is still
          experimental, any help in debugging is a plus.
