Fix non-terminated PCI match table in PowerMac IDE
The PCI device table in the powermac IDE driver isn't properly
terminated. Depending on how your kernel is linked and other random
factors, you can end up with this driver matched against any other PCI
device in your system, possibly crashing at boot.
Thanks to Heikki for tracking this down with me, the bug have been there
for some time, though it rarely hurts due to luck. In this case, the
switch from .22 to .23-rc9 is causing it to show up due to differences
in the resulting layout of .data I suppose.

xen: disable split pte locks for now
When pinning and unpinning pagetables, we must protect them against
being used by other CPUs, lest they see the pagetable in an
intermediate read-only-but-not-pinned state.
When using split pte locks, doing this properly would require taking
all the pte locks for the pagetable while pinning, but this may overflow
the PREEMPT_BITS part of the preempt counter if the process has mapped
more than about 512M of memory.
However, failing to take the pte locks causes write-protect faults when
the pageout code is trying to clear the Access bit on a pte which is part
of a freshy created and still being pinned process after fork.
This is a short-term fix until the problem is solved properly.

Remove unnecessary cast in prefetch()
It is ok to call prefetch() function with NULL argument, as specifically
commented in include/linux/prefetch.h. But in standard C, it is invalid
to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and
note #84).
prefetch() has a memory reference for its argument.
Newer gcc versions (4.3 and above) will use that to conclude that "x"
argument is non-null and thus wreaking havok everywhere prefetch() was
inlined.
Fixed by removing cast and changing asm constraint.
[ It seems in theory gcc 4.2 could miscompile this too; although no
cases known. In 2.6.24 we should probably switch to
__builtin_prefetch() instead, but this is a simpler fix for now.

Fix sys_remap_file_pages BUG at highmem.c:15!
Gurudas Pai reports kernel BUG at arch/i386/mm/highmem.c:15! below
sys_remap_file_pages, while running Oracle database test on x86 in 6GB
RAM: kunmap thinks we're in_interrupt because the preempt count has
wrapped.
That's because __do_fault expected to unmap page_table, but one of its
two callers do_nonlinear_fault already unmapped it: let do_linear_fault
unmap it first too, and then there's no need to pass the page_table arg
down.
Why have we been so slow to notice this? Probably through forgetting
that the mapping_cap_account_dirty test means that sys_remap_file_pages
nowadays only goes the full nonlinear vma route on a few memory-backed
filesystems like ramfs, tmpfs and hugetlbfs.
[ It also depends on CONFIG_HIGHPTE, so it becomes even harder to
trigger in practice. Many who have need of large memory have probably
migrated to x86-64..

[SPARC64]: Temporary workaround for PCI-E slot on T1000.
The PCI-E slot on T1000 connects directly to the Fire PCI chip with no
intervening bridges visible in the OBP tree.
Unfortunately the bus numbering of the device in that slot is
different (2) from the PCI host controller (0), and thus the
pci_bus_{read,write}_config_*() calls don't work out.
Complicating things further the Fire PCI controller has no config
space it responds to either.
For now treat this case specially so that devices in the slot work.
Longer term we need to perhaps cons up a dummy bridge between the Fire
and the PCI-E slot so that the bus hierarchy is complete inside of the
kernel and thus the bus numbering all works out right.

kills performance since normal loads allocate in the
L1 cache (unlike load-twin) and thus big memcpys swipe
the entire L1 D-cache.
We need to allocate a register window to implement this
properly, but that actually simplifies a lot of things
as a nice side-effect.

[TCP]: secure_tcp_sequence_number() should not use a too fast clock
TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock.
In order to follow network speed increase, we can use a faster clock, but
we should limit this clock so that the delay between two rollovers is
greater than MSL (TCP Maximum Segment Lifetime : 2 minutes)
Choosing a 64 nsec clock should be OK, since the rollovers occur every

x86_64: increase VDSO_TEXT_OFFSET for ancient binutils
For some reason old binutils genertate larger headers so increase the text
offset of the vdso to avoid linker errors.
Roland McGrath explains:
"There are extra symbols in the '.dynsym' section that are responsible
for the size difference (They also cause corresponding inflation in
'.gnu.version')
Older ld's wrongly generated these unneeded symbols in .dynsym. This
was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be
the first fixed version, but I have not verified for sure where the
cutoff was.
The unneeded symbols et al from old ld add almost 700 bytes excess.
This limits fairly tightly the amount by which the actual text and
data in the vDSO can grow in the future without pushing the whole
file over 4kb. If it does grow later on, we should consider changing
the layout with a config option or something to pack it better
without that padding, when building the kernel with newer binutils."

Lachlan McIlroy says:
It tried to fix an issue where log replay is replaying an inode cluster
initialisation transaction that should not be replayed because the inode
cluster on disk is more up to date. Since we don't log file sizes (we
rely on inode flushing to get them to disk) then we can't just replay
all the transations in the log and expect the inode to be completely
restored. We lose file size updates. Unfortunately this fix is causing
more (serious) problems than it is fixing.

i386: remove bogus comment about memory barrier
The comment being removed by this patch is incorrect and misleading.
In the following situation:
1. load ...
2. store 1 -> X
3. wmb
4. rmb
5. load a <- Y
6. store ...
4 will only ensure ordering of 1 with 5.
3 will only ensure ordering of 2 with 6.
Further, a CPU with strictly in-order stores will still only provide that
2 and 6 are ordered (effectively, it is the same as a weakly ordered CPU
with wmb after every store).
In all cases, 5 may still be executed before 2 is visible to other CPUs!
The additional piece of the puzzle that mb() provides is the store/load
ordering, which fundamentally cannot be achieved with any combination of
rmb()s and wmb()s.
This can be an unexpected result if one expected any sort of global ordering
guarantee to barriers (eg. that the barriers themselves are sequentially
consistent with other types of barriers). However sfence or lfence barriers
need only provide an ordering partial ordering of memory operations -- Consider
that wmb may be implemented as nothing more than inserting a special barrier
entry in the store queue, or, in the case of x86, it can be a noop as the store
queue is in order. And an rmb may be implemented as a directive to prevent
subsequent loads only so long as their are no previous outstanding loads (while
there could be stores still in store queues).
I can actually see the occasional load/store being reordered around lfence on
my core2. That doesn't prove my above assertions, but it does show the comment
is wrong (unless my program is -- can send it out by request).
So:
mb() and smp_mb() always have and always will require a full mfence
or lock prefixed instruction on x86. And we should remove this comment.

[x86 setup] Correct the SMAP check for INT 0x15, AX=0xe820
The e820 probe code was checking %edx, not %eax, for the SMAP
signature on return. This worked on *almost* all systems, since %edx
still contained SMAP from the call on entry, but on a handful of
systems it failed -- plus, we would have missed real mismatches.
The error output is "=d" to make sure gcc knows %edx is clobbered
here.

Setup dr_mode for USB-DR to peripheral as the default (host mode) doesn't make

Peripheral mode is preferable to OTG as the fsl_usb2_udc.c driver doesn't yet

[POWERPC] Fix cpm_uart driver for cpm1 machines
in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp.
On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't
be used for arithmetric compare operations with virtual addresses

[PPC] Fix cpm_dpram_addr returning phys mem instead of virt mem
cpm_dpram_addr returns physical memory of the DP RAM instead of
iomapped virtual memory. As there usually is a 1:1 MMU map of
the IMMR area, this is often not noticed. However, cpm_dpram_phys
assumes this iomapped virtual memory and returns garbage on the
1:1 mapped memory causing CPM1 uart console to fail.

The Yukon FE+ chip appears to have a hardware glitch that causes bogus

the status value is random garbage. As a temporary workaround until the

used of ignoring the status value on this chip.
Since this means trusting dodgy hardware values; add additional checking
of the receive packet length.
