Kenneth Chen f8220c7f15 [IA64] Delete erroneous copy_page.o in global lib-y list
copy_page.o appeared twice in arch/ia64/lib/Makefile. The
one in global lib-y is wrong where it should be just in
lib-$(CONFIG_ITANIUM).

Both copy_page.o and copy_page_mck.o are build for Itanium2
processor and the link order will pick up the low performing
copy_page function (originally written for itanium processor).
In this case, we really want the copy_page_mck.o for optimized
version.

Alex Williamson e8579e72ca [IA64, X86_64] fix swiotlb sizing
Fix swiotlb sizing to match what the comments and the kernel
parameters documentation indicate.  Given a default 16k page size kernel
(ia64) and a 2k swiotlb page size, we're off by a multiple of 8 trying
to size the swiotlb.  When specified on the boot line, the swiotlb is
made 8x bigger than requested.  When left to the default value, it's 8x
smaller than the comments indicate.  For x86_64 the multiplier would be
2x.  The patch below fixes this.  Now, what's a good default swiotlb
size?  Apparently we don't really need 64MB.

Zoltan Menyhart 08357f82d4 [IA64] improve flush_icache_range()
Check with PAL to see what the i-cache line size is for
each level of the cache, and so use the correct stride
when flushing the cache.

David Mosberger-Tang 2074615a13 [IA64] use fc.i for fluch_icache_range()
This is a small patch to switch fluch_icache_range() to use fc.i
instead of fc.  This would save time on processors which can establish
i-cache coherency without flushing the cache-line out to memory (not
that any current processors do).  On existing processors, fc.i behaves
like fc.  The only caveat is that very old assemblers may not know
about fc.i yet.

David Mosberger-Tang 9df6f705c0 [IA64] fix typos caught by new assembler
Patch below fixes 3 trivial typos which are caught by the new
assembler (v2.169.90).  Please apply.

[Note: fix to memcpy that was also part of this patch was separately
 applied from patches by H.J. and Andreas ... so the delta here only
 has the other two fixes. -Tony]

* src is unaligned and
* dst is near the end of a page and
* the page after dst is unmapped.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
