2011-01-13x86: support XZ-compressed kernelLasse Collin
This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.

2011-01-13rapidio: fix hang on RapidIO doorbell queue full conditionThomas Taranowski
In fsl_rio_dbell_handler() the code currently simply acknowledges the QFI queue full interrupt, but does nothing to resolve the queue full condition. Instead, it jumps to the end of the isr. When a queue full condition occurs, the isr is then re-entered immediately and continually, forever. The fix is to just fall through and read out current doorbell entries.

2011-01-13drivers/staging/olpc_dcon: convert to new cs5535 gpio APIAndres Salomon
Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver.

2011-01-13kernel: clean up USE_GENERIC_SMP_HELPERSAmerigo Wang
For arch which needs USE_GENERIC_SMP_HELPERS, it has to select USE_GENERIC_SMP_HELPERS, rather than leaving a choice to user, since they don't provide their own implementions. Also, move on_each_cpu() to kernel/smp.c, it is strange to put it in kernel/softirq.c. For arch which doesn't use USE_GENERIC_SMP_HELPERS, e.g. blackfin, only on_each_cpu() is compiled.

Occasionally the system gets into a state where the CMOS clock has gotten slightly ahead of current time and the periodic update of RTC fails. The message is a nuisance and repeats spamming the log. See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS Rather than just removing the message, make it show only once and reduce severity since it indicates a normal and non urgent condition.

2011-01-13omap4: Fix ULPI PHY init for ES1.0 SDPTony Lindgren
Commit 6aa85a5ae610106d89e50c7e1f760c56d12f9bc4 (omap4: 4430sdp: enable the ehci port on 4430SDP) added code to enable EHCI support on 4430sdp board. Looks like the ULPI pin does not seem to be muxed properly on ES1.0 SDP and this causes the system to reboot when the ULPI PHY is enabled. Fix this by muxing the pin, this is the same setting for both ES1.0 and ES2.0. Also add checking for gpio_request.

2011-01-12cpuidle/x86/perf: fix power:cpu_idle double end events and throw cpu_idle ↵Thomas Renninger
events from the cpuidle layer Currently intel_idle and acpi_idle driver show double cpu_idle "exit idle" events -> this patch fixes it and makes cpu_idle events throwing less complex. It also introduces cpu_idle events for all architectures which use the cpuidle subsystem, namely: - arch/arm/mach-at91/cpuidle.c - arch/arm/mach-davinci/cpuidle.c - arch/arm/mach-kirkwood/cpuidle.c - arch/arm/mach-omap2/cpuidle34xx.c - arch/drivers/acpi/processor_idle.c (for all cases, not only mwait) - arch/x86/kernel/process.c (did throw events before, but was a mess) - drivers/idle/intel_idle.c (did throw events before) Convention should be: Fire cpu_idle events inside the current pm_idle function (not somewhere down the the callee tree) to keep things easy. Current possible pm_idle functions in X86: c1e_idle, poll_idle, cpuidle_idle_call, mwait_idle, default_idle -> this is really easy is now. This affects userspace: The type field of the cpu_idle power event can now direclty get mapped to: /sys/devices/system/cpu/cpuX/cpuidle/stateX/{name,desc,usage,time,...} instead of throwing very CPU/mwait specific values. This change is not visible for the intel_idle driver. For the acpi_idle driver it should only be visible if the vendor misses out C-states in his BIOS. Another (perf timechart) patch reads out cpuidle info of cpu_idle events from: /sys/.../cpuidle/stateX/*, then the cpuidle events are mapped to the correct C-/cpuidle state again, even if e.g. vendors miss out C-states in their BIOS and for example only export C1 and C3. -> everything is fine.

2011-01-12ACPI, intel_idle: Cleanup idle= internal variablesThomas Renninger
Having four variables for the same thing: idle_halt, idle_nomwait, force_mwait and boot_option_idle_overrides is rather confusing and unnecessary complex. if idle= boot param is passed, only set up one variable: boot_option_idle_overrides Introduces following functional changes/fixes: - intel_idle driver does not register if any idle=xy boot param is passed. - processor_idle.c will also not register a cpuidle driver and get active if idle=halt is passed. Before a cpuidle driver with one (C1, halt) state got registered Now the default_idle function will be used which finally uses the same idle call to enter sleep state (safe_halt()), but without registering a whole cpuidle driver. That means idle= param will always avoid cpuidle drivers to register with one exception (same behavior as before): idle=nomwait may still register acpi_idle cpuidle driver, but C1 will not use mwait, but hlt. This can be a workaround for IO based deeper sleep states where C1 mwait causes problems.
