Subject: [GIT PATCH] ACPI patches for 2.6.25-rc1

Hi Linus,

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release

This batch...
fixes two suspend regressions
tidies up the recently updated cpuidle code, including adding documentation.
and some other fluff.

This will update the files shown below.

thanks!

-Len

    ACPI, cpuidle: Clarify C-state description in sysfs
    
    Add a new sysfs entry under cpuidle states. desc - can be used by driver to
    communicate to userspace any specific information about the state.
    This helps in identifying the exact hardware C-states behind the ACPI C-state
    definition.
    
    Idea is to export this through powertop, which will help to map the C-state
    reported by powertop to actual hardware C-state.

    ACPI: fix suspend regression due to idle update
    
    Earlier patch (bc71bec91f9875ef825d12104acf3bf4ca215fa4) broke
    suspend resume on many laptops. The problem was reported by
    Carlos R. Mafra and Calvin Walton, who bisected the issue to above patch.
    
    The problem was because, C2 and C3 code were calling acpi_idle_enter_c1
    directly, with C2 or C3 as state parameter, while suspend/resume was in
    progress. The patch bc71bec started making use of that state information,
    assuming that it would always be referring to C1 state. This caused the
    problem with suspend-resume as we ended up using C2/C3 state indirectly.
    
    Fix this by adding acpi_idle_suspend check in enter_c1.
