2009-02-02powerpc: Fix oops on some machines due to incorrect pr_debug()Benjamin Herrenschmidt
Recently, a patch left DEBUG enabled in the powerpc common PCI code, resulting in an old bug in a pr_debug() statement to show up and cause a NULL dereference on some machines. This fixes the pr_debug() statement and reverts to DEBUG not being force-enabled in that file. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-01-29powerpc/5200: Bugfix for PCI mapping of memory and IMMRGrant Likely
This patch ensures that memory gets properly mapped into the PCI address space. Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.

2009-01-28powerpc/mm: Fix handling of _PAGE_COHERENT in BAT setup codeGerhard Pircher
_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set. This will work on normal SMP setups because we force-set CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

2009-01-28powerpc/pseries: Correct VIO bus accounting problem in CMO env.Robert Jennings
In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path.

2009-01-16powerpc: Get the number of SLBs from "slb-size" propertyMichael Neuling
The PAPR says that the property for specifying the number of SLBs should be called "slb-size". We currently only look for "ibm,slb-size" because this is what firmware actually presents. This patch makes us look for the "slb-size" property as well and in preference to the "ibm,slb-size". This should future proof us if firmware changes to match PAPR.

2009-01-13powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-BootsAnton Vorontsov
FSL U-Boots use /soc8315@e0000000 node to search and fixup serial nodes' clock-frequency properties. Though in upstream kernels we use new naming convention -- for IMMR address space dts files specify /immr@e0000000 nodes. This makes FSL U-Boots fail to fixup the clock frequencies, and that leads to serial ports misbehaviour. We can workaround the issue by filling the clock frequency values manually. p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for ethernet nodes, so users should either change the .dts file locally or set MAC address via `ifconfig hw ether' command.

2009-01-13powerpc/powermac: Fix occasional SMP boot failureBenjamin Herrenschmidt
The PowerMac kernel occasionally fails to bring up the secondary CPUs on SMP, the trigger factor seem to be fairly random and related to location of code and data. This appears to be due to the initial loading of the TOC value by the secondary processor which now happens before we clear HID4:RM_CI (Real Mode Cache Invalidate). This bit should really be cleared before we do any load or store other than fetching code. This fix works based on the assumption that all SMP 64-bit PowerMacs use variants of the 970, which fortunately is true, by explicitely clearing that bit, adding an slbia for good measure as RM_CI mode is known to create bogus ERAT entries. I also removed some spurrious debug output that was left enabled by mistake while at it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Enforce that the crash kernel region never overlaps the current kernel, as it will be written directly on kexec load. Also, default to the previous KDUMP_KERNELBASE if the start is 0. Other architectures (x86, ia64) state that specifying the start address 0 (or omitting it) will result in the kernel allocating it.
