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: Stephen Rothwell

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 declarationsSigned-off-by: Stephen Rothwell

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: Stephen Rothwell

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: Stephen Rothwell

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

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

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

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: David Gibson

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: Benjamin Herrenschmidt

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

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: Kumar Gala

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.

us a hint. I know we may be booting vmlinux someday, but don't care about
it for now.Signed-off-by: Coywolf Qi Hunt

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: Abhijit Karmarkar

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: Hugh Dickins

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: Hugh Dickins

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"?Signed-off-by: Hugh Dickins

rme96xx busmaster_malloc miscalculates and fails to set PageReserved on any

Remove part of comment on linking new vma in dup_mmap: since anon_vma rmap

Strict mbind's check for currently mapped pages being on node has been
using a slow loop which re-evaluates pgd, pud, pmd, pte for each entry:
replace that by a standard four-level page table walk like others in mm.
Since mmap_sem is held for writing, page_table_lock can be taken at the
inner level to limit latency.Signed-off-by: Hugh Dickins
