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:

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:

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:

I am always trying to make sure I've booted the right kernel after a new install. Too paranoid maybe. But I guess there're other people like me. So let's make kbuild display the compile version number at the end to give us a hint. I know we may be booting vmlinux someday, but don't care about it for now. Signed-off-by:

It's common practice to msync a large address range regularly, in which often only a few ptes have actually been dirtied since the previous pass. sync_pte_range then goes much faster if it tests whether pte is dirty before locating and accessing each struct page cacheline; and it is hardly slowed by ptep_clear_flush_dirty repeating that test in the opposite case, when every pte actually is dirty. But beware, s390's pte_dirty always says false, since its dirty bit is kept in the storage key, located via the struct page address. So skip this optimization in its case: use a pte_maybe_dirty macro which just says true if page_test_and_clear_dirty is implemented. Signed-off-by:

Remember that ironic get_user_pages race? when the raised page_count on a page swapped out led do_wp_page to decide that it had to copy on write, so substituted a different page into userspace. 2.6.7 onwards have Andrea's solution, where try_to_unmap_one backs out if it finds page_count raised. Which works, but is unsatisfying (rmap.c has no other page_count heuristics), and was found a few months ago to hang an intensive page migration test. A year ago I was hesitant to engage page_mapcount, now it seems the right fix. So remove the page_count hack from try_to_unmap_one; and use activate_page in unuse_mm when dropping lock, to replace its secondary effect of helping swapoff to make progress in that case. Simplify can_share_swap_page (now called only on anonymous pages) to check page_mapcount + page_swapcount == 1: still needs the page lock to stabilize their (pessimistic) sum, but does not need swapper_space.tree_lock for that. In do_swap_page, move swap_free and unlock_page below page_add_anon_rmap, to keep sum on the high side, and correct when can_share_swap_page called. Signed-off-by:

A small optimization to do_wp_page's check for whether to avoid copy by reusing the page already mapped. It can never share a cached file page, nor can it share a reserved page (often the empty zero page), so it's a waste of time to lock and unlock in those cases. Which nowadays can both be neatly excluded by a preliminary PageAnon test. Christoph has reported that a preliminary page_count test proved valuable for scalability here, but PageAnon covers more common cases all at once. Signed-off-by:

Since its birth, get_user_pages has been calling a misguided get_page_map function. follow_page has already returned NULL if the pfn is invalid, we cannot reach an invalid pfn from a validated struct page. Remove get_page_map, and the messy rewind in get_user_pages to cope with its failure. Oh, and could we please call that "struct page *page" like everywhere else, instead of "struct page *map"?
