We dont use the hardware referenced and changed bits and setting them early avoids a store to memory. We already do this for userspace hptes but not kernel ones. Do it. Signed-off-by:

Currently we dynamically allocate the fake parent device for all devices on the vio bus. This patch statically allocates it. This also allows us to reuse it for the iSeries "generic" vio device (that is used for passing to dma routines when communicating with the hypervisor without a device involved). Also unexport vio_bus_type as it is never used in modules. Signed-off-by:

This patch allows iSeries to build with CONFIG_PCI=n. This is useful for partitions that have only virtual I/O. Signed-off-by:

This patch just removes some dead code, fixes messages that referred to the file this code used to be in and inserts XmPciLpEvent_init into its caller. Signed-off-by:

This patch just merges XmPciLpEvent.c into iSeries_irq.c (the only caller of its only external function). XmPciLpEvent.c just contained the lowlevel iSeries irq code. Signed-off-by:
-
Stephen Rothwell authored
This patch is just simple cleanups to the iSeries irq code. - whitespace and comments - rearrange some functions to avoid forward declarations - remove XmPciLpEvent.h as its functions were declared elsewhere - remove decaration of function that no longer exists No semantic changes. Signed-off-by:

The AgentId, PhbId, FrameId, CardLocation and Location members of iSeries_Device_Node are stored early in the boot process just so that a message about the device can be printed later in the boot process. Remove them and construct the message by doing the VPD parsing at the time the message is printed. Also remove a few unused defines in iSeries_VpdInfo.c. Signed-off-by:

The IoRetry member of iSeries_Devide_Node is really only used locally, so remove it and replace it with a local variable. Signed-off-by:

Remove no longer used things from iSeries_pci.h. Signed-off-by:

Stephen Rothwell authored
Clean up iSeries_VpdInfo.c: - white space and comment fixes - make a function static - the functions here are only called from iSeries_pci.c, so CONFIG_PCI will be set (so remove check) - only build when CONFIG_PCI is set - remove unneeded includes and cast Signed-off-by:

The iommu_table_cb structure is iSeries specific, so move it to the header file that declares the function we pass it to. vio_tce_table and iommu_setup_iSeries no longer exist, so remove their declarations. Signed-off-by:

Stephen Rothwell authored
The file arch/ppc64/kernel/iSeries_pci_reset contains only one function that is not use anywhere (any more). Remove it. This function is the only user of the ReturnCode member of iSeries_Device_Node, so remove that as well. Signed-off-by:

Last of this round of the iSeries header cleanups - don't have two defines for the same thing (HvMaxArchitectedLps and HvMaxArchitectedVirtualLans) - HvCallSc.h only needs linux/types.h - remove unused struct definition - add "extern" to some more function declarations Signed-off-by:
-
Stephen Rothwell authored
This patch removes some unused bits from HvCall.h and some unneeded #includes from other files. Also includes ItLpQueue.h in paca.h in preference to a stub declaration of struct ItLpQueue. Signed-off-by:

Now that the only users of things in HvCallCfg.h are in HvLpConfig.h, merge in the bit we need and remove HvCallCfg.h. Signed-off-by:
-
Stephen Rothwell authored
This patch removes from the iSeries header files a large number of inline functions that are not used. It also changes the only caller of a HvCallCfg function that is outside HvLpConfig.h to its equivalent HvLpConfig function and no longer includes HvCallCfg.h where it is not needed. Signed-off-by:

include/asm-ppc64/iSeries/LparData.h just included a whole lot of other files to declare variables that would be better declared in those other files. So, remove it. This will reduce that number of things needed to be included in most cases to access the relevant variables. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au Signed-off-by:

This patch does some obvious code cleanups in the iSeries headers files. - simplifies the bodies of lots of inline functions - parenthesises a macros result - removes C++ wrapping - adds "extern" to some function declarations There are no semantic changes. Signed-off-by:

[PATCH] ppc64: override command line AS/LD/CC variables when adding -m64 and co for biarch compilers The following kind of calls currently fails : make ARCH=ppc64 CC="gcc-3.4" Since the code for detecting a biarch compiler and adding the needed 64bit magic argument fails if the AS/LD/CC commands are overriden in the command line. The attached patch fixes this by using the make override and += directive, but i am not 100% sure this will work without gmake, as i am no Makefile expert.

Currently ppc64 has two mm_structs for the kernel, init_mm and also ioremap_mm. The latter really isn't necessary: this patch abolishes it, instead restricting vmallocs to the lower 1TB of the init_mm's range and placing io mappings in the upper 1TB. This simplifies the code in a number of places and eliminates an unecessary set of pagetables. It also tweaks the unmap/free path a little, allowing us to remove the unmap_im_area() set of page table walkers, replacing them with unmap_vm_area(). Signed-off-by:

This patch kills the whole embedded System.map mecanism and the bootloader-passed System.map that was used to provide symbol resolution in xmon. Instead, xmon now uses kallsyms like ppc64 does. No hurry getting that in Linus tree, let it be tested in -mm for a while first and make sure it doesn't break various embedded configs. Signed-off-by:

This patch avoids recursive crash (leading to kernel stack overflow) in die() on CHRP/PReP machines when CONFIG_PMAC_BACKLIGHT=y. set_backlight_* functions are placed in pmac section, which is discarded when _machine != _MACH_Pmac. Signed-off-by:

4xx and Book-E PPC's have several exception levels. The code to handle each level is fairly regular. Turning the code into macro's will ease the handling of future exception levels (debug) in forth coming chips. Signed-off-by:

Made the number of TLB CAM entries private and converted the board consumers to use num_tlbcam_entries which is setup at boot time from configuration registers. This way the only consumers of the #define NUM_TLBCAMS are the arrays used to manage the TLB. Signed-off-by:

The MPC8548 has 48 internal interrupts and 12 external interrupts. The previous generation PowerQUICC III devices only had 32 internal and 12 external interrupts on the primary interrupt controller. Expanded the number of internal interrupts to 48 for all PowerQUICC III processors and moved the interrupt numbers for the external after the 48 internal interrupt lines, rather than putting the 12 new internal interrupts at the end and ifdef'ng the whole mess. As parted of this created a macro which represents the internal interrupt senses since they are the same on all PQ3 processors. Signed-off-by:
