2010-05-13sh: get rid of mstp32 clock name and idMagnus Damm
Remove the name and the id from SH_CLK_MSTP32(). Now when lookups are handled by clkdev they are not needed anymore. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This patch adds sh7366 MSTP enums for mstp_clks[] index. The MSTP bit for the SIU is removed as well since it is not included in the documentation. Most likely an old copy paste error from sh7722. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-05-06sh: Make initrd detection more robust.Paul Mundt
Various boot loaders go to various extents to thwart the initrd detection logic (mostly on account of not being able to be bothered with adhering to the established boot ABI), so we make the detection logic a bit more robust. This makes it possible to work around the SDK7786's firmware's attempts to thwart compressed image booting. Victory is mine. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-29sh: native_cpu_disable() build error when CONFIG_HOTPLUG_CPU=nMatt Fleming

Add CONFIG_VIRTUALIZATION to the SH architecture and include the virtio code there. Used to enable the virtio drivers under QEMU. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-27sh: make latencytop available on SMP, too.Paul Mundt
The UP dependency was inherited from ARM, which seems to have run in to it due to the stacktrace code not being available for SMP in certain cases, as we don't have this particular limitation there is no specific need to block on the SMP dependency. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-04-26sh: CPU hotplug support for SH-X3 SMP.Paul Mundt
This wires up CPU hotplug for SH-X3 SMP CPUs. Presently only secondary cores can be hotplugged given that the boot CPU has to contend with the broadcast timer. When real local timers are implemented this restriction can be lifted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: CPU hotplug support.Paul Mundt
This adds preliminary support for CPU hotplug for SH SMP systems. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: cache secondary CPUs idle loop.Paul Mundt
This provides a cache of the secondary CPUs idle loop for the cases where hotplug simply enters a low power state instead of resetting or powering off the core. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: flag smp_store_cpu_info() __cpuinit.Paul Mundt
smp_store_cpu_info() is presently flagged as __init, but is called by start_secondary() which is __cpuinit, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: provide percpu CPU states for hotplug notifiers.Paul Mundt
This provides percpu CPU states in preparation for CPU hotplug and the associated notifier chains. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: Make sure all SH-X3 cores are populated in the present CPU map.Paul Mundt
This iterates over the maximum number of CPUs we plan to support and makes sure they're all set in the present CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: convert online CPU map twiddling to cpumask.Paul Mundt
This converts from cpu_set() for the online map to set_cpu_online(). The two online map modifiers were the last remaining manual map manipulation bits, with this in place everything now goes through cpumask. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: arch/sh/kernel/setup.c needs asm/smp.h.Paul Mundt
With the platform ops migration, the definitions still need to be included in the CONFIG_SMP=n case, so make the asm/smp.h include explicit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: Flag present CPUs hotpluggable in topology registration.Paul Mundt
When registering CPUs in the topology initialization ensure that all of the present CPUs are flagged as hotpluggable. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-04-26sh: sh7751 pci controller io port fixMagnus Damm
This patch updates the sh7751 pci code to handle io ports correctly. The code is based on the sh7788x implementation. Tested on a R2D-1 board with CONFIG_8139TOO_PIO=y. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: Fix maximum number of SCIF ports in R2D defconfigsMagnus Damm

2010-04-26SH: fix TS field shift calculation for DMA driversGuennadi Liakhovetski
CHCR_TS_HIGH_SHIFT is defined as a shift of TS high bits in CHCR register, relative to low bits. The TS_INDEX2VAL() macro has to take this into account. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-04-26sh: invoke oom-killer from page faultNick Piggin
As explained in commit 1c0fe6e3bd, we want to call the architecture independent oom killer when getting an unexplained OOM from handle_mm_fault, rather than simply killing current.

Commit fda48a0d7a84 (tcp: bind() fix when many ports are bound) introduced a bug on IPV6 part. We should not call ipv6_addr_any(inet6_rcv_saddr(sk2)) but ipv6_addr_any(inet6_rcv_saddr(sk)) because sk2 can be IPV4, while sk is IPV6. Reported-by: Michael S.

2010-04-25sh: Use correct mask when comparing PMB DATA array valuesMatt Fleming
Previously we were masking the PMB DATA array values with the value of __MEMORY_START | PMB_V, which misses some PFN bits off the mask. Signed-off-by: Matt Fleming <matt@console-pimps.org>
2010-04-25sh: Do not try merging two 128MB PMB mappingsMatt Fleming
There is a logic error in pmb_merge() that means we will incorrectly try to merge two 128MB PMB mappings into one mapping. However, 256MB isn't a valid PMB map size and pmb_merge() will actually drop the second 128MB mapping. This patch allows my SDK7786 board to boot when configured with CONFIG_MEMORY_SIZE=0x10000000. Signed-off-by: Matt Fleming <matt@console-pimps.org>
2010-04-25sh: Fix zImage load address when CONFIG_32BIT=yMatt Fleming
We can't necessarily use the P1SEG region to access RAM when running in 32BIT mode, so use CONFIG_MEMORY_START as the base address. Signed-off-by: Matt Fleming <matt@console-pimps.org>
2010-04-25sh: Fix address to decompress at when CONFIG_32BIT=yMatt Fleming
When running in 32BIT mode the P1SEG region doesn't necessarily provide a window onto RAM (it depends how the bootloader setup the PMB). The correct location to place the decompressed kernel is the physical address of _text. Signed-off-by: Matt Fleming <matt@console-pimps.org>
2010-04-25sh: Assembly friendly __pa and __va definitionsMatt Fleming
This patch defines ___pa and ___va which return the physical and virtual address of an address, respectively. These macros are suitable for calling from assembly because they don't include the C casts required by __pa and __va. Signed-off-by: Matt Fleming <matt@console-pimps.org>
