2011-01-13rapidio: fix hang on RapidIO doorbell queue full conditionThomas Taranowski1-1/+0
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 Salomon1-3/+7
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 Wang2-9/+2
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.

2011-01-13set_rtc_mmss: show warning message only onceStephen Hemminger7-7/+7
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.

2011-01-11x86: Use PCI method for enabling AMD extended config space before MSR methodJan Beulich4-28/+63
While both methods should work equivalently well for the native case, the Xen Dom0 case can't reliably work with the MSR one, since there's no guarantee that the virtual CPUs it has available fully cover all necessary physical ones. As per the suggestion of Robert Richter the patch only adds the PCI method, but leaves the MSR one as a fallback to cover new systems the PCI IDs of which may not have got added to the code base yet. The only change in v2 is the breaking out of the new CPI initialization method into a separate function, as requested by Ingo.

2011-01-11powerpc/pseries: Fix VPHN build errors on non-SMP systemsJesse Larrew2-12/+17
The header asm/hvcall.h was previously included indirectly via smp.h. On non-SMP systems, however, these declarations are excluded and the build breaks. This is easily fixed by including asm/hvcall.h directly. The VPHN feature is only meaningful on NUMA systems that implement the SPLPAR option, so exclude the VPHN code on systems without SPLPAR enabled. Also, expose unmap_cpu_from_node() on systems with SPLPAR enabled, even if CONFIG_HOTPLUG_CPU is disabled. Lastly, map_cpu_to_node() is now needed by VPHN to manipulate the node masks after boot time, so remove the __cpuinit annotation to fix a section mismatch.

2011-01-10Blackfin: bf518f-ezbrd: fix dsa resourcesSonic Zhang1-9/+8
On bf518-ezbrd with DSA Ethernet switch enabled, on chip MAC is connecting to phy at address 3. If allowing the netdevice framework to probe both 3 phys of the switch when registering MAC phy, phy at address 1 is checked for link active status other than phy at address 3. If connecting a cable to port 2 and leave port 1 open, link status in phy 2 and 3 are online, while that in phy 1 is offline. So, the phy layer sets wrong offline status to net device on port 3. In this case, no data can be transferred via ethernet port 2. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: move "-m elf32bfin" to general LDFLAGSMike Frysinger1-1/+1
Common code now invokes the linker directly which causes build failures when using an FDPIC toolchain. So move the emulation setting out of the module-specific LDFLAGS and into the common LDFLAGS. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

We check its value at runtime, so we want to avoid garbage across runs. Signed-off-by: Vivi Li <vivi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: kgdb: disable preempt schedule when running single step in kgdbSonic Zhang1-1/+7
Otherwise, gdb continue operation after a breakpoint is hit may trap into endless breakpoint. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: kgdb: disable interrupt when single stepping in ADEOSSonic Zhang1-0/+20
When ADEOS and kgdb are both enabled, single step in linux kernel may be scheduled to Xenomai core after return from interrupt handlers. This blocks gdb continue operation after a break point is hit. So, disable interrupt when running gdb single step. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: SMP: kgdb: apply anomaly 257 work aroundSonic Zhang1-1/+5
When run kgdb testing, it looks like coreb hangs in single step or trap exception without handling anomaly 05000257 properly on bf561 v0.5. But, the anomaly list says it apply to bf561 v0.4 and bellow. Apply its work around to 0.5 temporarily until the behavior and the root cause can be confirmed by the hardware team.

2011-01-10Blackfin: fix building IPIPE code when XIP is enabledMike Frysinger1-2/+2
The low level assembly needs to use the pseudo_long_call helper so that we use the right call insn when doing kernel XIP. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: SMP: kgdb: flush core internal write buffer before flushinvSonic Zhang1-0/+5
KGDB single step in SMP kernel may hang forever in flushinv without a CSYNC ahead. This is because the core internal write buffers need to be flushed before invalidating the data cache to make sure the insn fetch is not out of sync.
