2009-12-07mac80211: Fix dynamic power save for scanning.Vivek Natarajan
Not only ps_sdata but also IEEE80211_CONF_PS is to be considered before restoring PS in scan_ps_disable(). For instance, when ps_sdata is set but CONF_PS is not set just because the dynamic timer is still running, a sw scan leads to setting of CONF_PS in scan_ps_disable instead of restarting the dynamic PS timer. Also for the above case, a null data frame is to be sent after returning to operating channel which was not happening with the current implementation. This patch fixes this too.

2009-12-07mac80211: recalculate idle later in MLMEJohannes Berg
hwsim testing has revealed that when the MLME recalculates the idle state of the device, it sometimes does so before sending the final deauthentication or disassociation frame. This patch changes the place where the idle state is recalculated, but of course driver transmit is typically asynchronous while configuration is expected to be synchronous, so it doesn't fix all possible cases yet.

The bssid can be zero when null data template is set in wl1251_op_config(). It's enough, and especially safe, to set it once after association. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Add a low_ops->dbam_to_cs member which is family-specific and replaces low_ops->dbam_map_to_pages since the pages calculation is a one liner now. Further cleanups, while at it: - shorten family name defines - align amd64_family_types struct members Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: cleanup f10_early_channel_countBorislav Petkov
Do not read DCLR[01] again since this is done in amd64_read_mc_registers() earlier. There can be more than two physical DIMMs present so clamp the channels value to max 2. Also, do not report DCT data width - it is also done earlier. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: dump DIMM sizes on K8 tooBorislav Petkov
Extend f10_debug_display_dimm_sizes to dump the logical DIMMs configuration on K8 revF too. Remove the ganged arg since we print the DCT operating mode (ganged vs unganged) earlier. Also, DCT csrow configuration is relevant therefore dump it as KERN_DEBUG instead of only on debug builds. Remove misleading DIMM output since there's no reliable way of mapping of chip selects to actual physical DIMMs. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2009-12-07amd64_edac: wrap-up pci config read error handlingBorislav Petkov
Add a pci config read wrapper for signaling pci config space access errors instead of them being visible only on a debug build. This is important on amd64_edac since it uses all those pci config register values to access the DRAM/DIMM configuration of the nodes. In addition, the wrapper makes a _lot_ (look at the diffstat!) of error handling code superfluous and improves much of the overall code readability by removing error handling details out of the way.

2009-12-07amd64_edac: make DRAM regions output more human-readableBorislav Petkov
Do not shift the TOP_MEM and TOP_MEM2 values by 23 but rather save the whole 64-bit value read from the MSR. Although the TOP_MEM/TOP_MEM2 bits are only a subset of the 64bit register, the values are correct since the remaining bits are Read-As-Zero and no shifting is needed. Also, cleanup DRAM base/limit debug output. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

This reverts commit f20941f334d8fdb6b598658979709b4e94cd034b. Sergei Shtylyov notes "You call min() on uncomparables [in mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second argument will always "win" as a minimal one" Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related to mwdma_clip_to_pio(). The function can return values between 0 and 4 which obviously won't work well for the new code below for values >2 (i.e. resulting in out-of-bounds array access for the common-case of dev->pio_mode == XFER_PIO_4)." Bartlomiej Zolnierkiewicz also notes the patch is incomplete, failing to update MWDMA mode masks. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-12-07x86: Fix bogus warning in apic_noop.apic_write()Thomas Gleixner
apic_noop is used to provide dummy apic functions. It's installed when the CPU has no APIC or when the APIC is disabled on the kernel command line. The apic_noop implementation of apic_write() warns when the CPU has an APIC or when the APIC is not disabled. That's bogus.
