[MIPS] Always use virt_to_phys() when translating kernel addresses
This patch fixes two places where we used plain 'x - PAGE_OFFSET' to
achieve virtual to physical address convertions. This type of convertion
is no more allowed since commit
6f284a2ce7b8bc49cb8455b1763357897a899abb.

[PATCH] x86_64: avoid sending LOCAL_TIMER_VECTOR IPI to itself
Ray Lee reported, that on an UP kernel with "noapic" command line option
set, the box locks hard during boot.
Adding some debug printks revealed, that the last action on the box
before stalling was "Send IPI" - a debug printk which was put into
smp_send_timer_broadcast_ipi().
It seems that send_IPI_mask(mask, LOCAL_TIMER_VECTOR) fails when
"noapic" is set on the command line on an UP kernel.
Aside of that it does not make much sense to trigger an interrupt
instead of calling the function directly on the CPU which gets the
PIT/HPET interrupt in case of broadcasting.

[PATCH] i386: clear segment register padding in core dumps
The segment register slots in struct pt_regs are padded to 32 bits.
Some of these are stored with instructions like "pushl %es", which
leaves the high 16 bits as they were. So the high bits of these
fields in struct pt_regs contain kernel stack garbage. These bits are
ignored by everything and never leak to user space, except in core
dumps. The user struct pt_regs is always at the base of the thread's
kernel stack and so it seems unlikely the information that leaks from
here is ever worthwhile so as to be a security concern, but I'm not
sure about that. It has been this way for ages; userland consumers of
core dumps all mask off these high bits themselves. So it is not urgent.
This change masks off the padding bits of the segment register slots
in core dumps. ptrace already masks off these high bits, so this
makes the values in core dumps consistent with what ptrace would
report just before the process died.
As I read the processor manuals, the cs and ss values will always be
padded with zero bits rather than stack garbage. But unlike "pushl %es",
this is not simple to test with a userland program. So I added the two
instructions rather than wonder if they are really never necessary.
I think that x86_64 does not have this problem (for either 32-bit or
64-bit processes). It only uses "mov" instructions from segment
registers, which zero-extend.

[PATCH] i386: disable local apic timer via command line or dmi quirk
The local APIC timer stops to work in deeper C-States. This is handled by
the ACPI code and a broadcast mechanism in the clockevents / tick managment
code.
Some systems do not expose the deeper C-States to the kernel, but switch
into deeper C-States behind the kernels back. This delays the local apic
timer interrupts for ever and makes the systems unusable.
Add a command line option to disable the local apic timer and a dmi
quirk for known broken systems.
Andi sayeth:
While not wrong by itself i think it is still better to use some heuristic
-- like "has battery in ACPI" With the DMI table if the problem is more wide
spread we will just continue extending it.
But anyways should be ok now for .21 although I'm not really happy with

[PATCH] i386: clockevents fix breakage on Geode/Cyrix PIT implementations
The PIT has no dedicated mode for shut down. The only way to disable PIT
is to put it into one shot mode. AMD implementations of PIT on Geode
(also observed on Cyrix) are confused by an "empty" transition from
CLOCK_EVT_MODE_UNUSED to CLOCK_EVT_MODE_SHUTDOWN, which puts the PIT
into one shot mode momentarily.
I realized after staring helpless at the bug report
http://bugzilla.kernel.org/show_bug.cgi?id=8027 for quite a while, that
the only change, which might influence the bogomips calibration, is the
above transition during the PIT initialization.
Avoiding the unnecessary switch to oneshot and later to periodic mode
fixes the weird bogomips value and also the resulting slowness.
The fix is confirmed on OLPC and another Geode based box.
Note: this is unrelated to the Dual Core problem discussed here:

IB/ipoib: Fix thinko in packet length checks
The packet length checks in ipoib are broken: we add 4 bytes (IPoIB
encapsulation header) when sending a packet, not 20 bytes (hardware
address length) to each packet. Therefore, if connected mode is
enabled so that the interface MTU is larger than the multicast MTU,
IPoIB may end up trying to send too-long multicast packets. For
example, multicast is broken if a message of size 2048 bytes is sent
on an interface with UD MTU 2048, because 2048 is bigger than the real
limit of 2044 but the code tests against the wrong limit of 2060.

Currently NAT not only reroutes packets in the OUTPUT chain when the

[CRYPTO] api: scatterwalk_copychunks() fails to advance through scatterlist
In the loop in scatterwalk_copychunks(), if walk->offset is zero,
then scatterwalk_pagedone rounds that up to the nearest page boundary:
walk->offset += PAGE_SIZE - 1;
walk->offset &= PAGE_MASK;
which is a no-op in this case, so we don't advance to the next element
of the scatterlist array:
if (walk->offset >= walk->sg->offset + walk->sg->length)
scatterwalk_start(walk, sg_next(walk->sg));
and we end up copying the same data twice.
It appears that other callers of scatterwalk_{page}done first advance
walk->offset, so I believe that's the correct thing to do here.
This caused a bug in NFS when run with krb5p security, which would
cause some writes to fail with permissions errors--for example, writes
of less than 8 bytes (the des blocksize) at the start of a file.

[IA64] min_low_pfn and max_low_pfn calculation fix
We have seen bad_pte_print when testing crashdump on an SN machine in
recent 2.6.20 kernel. There are tons of bad pte print (pfn < max_low_pfn)
reports when the crash kernel boots up, all those reported bad pages
are inside initmem range; That is because if the crash kernel code and
data happens to be at the beginning of the 1st node. build_node_maps in
discontig.c will bypass reserved regions with filter_rsvd_memory. Since
min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn
will be greater than kernel code and data.
Because pages inside initmem are freed and reused later, we saw
pfn_valid check fail on those pages.
I think this theoretically happen on a normal kernel. When I check
min_low_pfn and max_low_pfn calculation in contig.c and discontig.c.
I found more issues than this.
1. min_low_pfn and max_low_pfn calculation is inconsistent between
contig.c and discontig.c,
min_low_pfn is calculated as the first page number of boot memmap in
contig.c (Why? Though this may work at the most of the time, I don't
think it is the right logic). It is calculated as the lowest physical
memory page number bypass reserved regions in discontig.c.
max_low_pfn is calculated include reserved regions in contig.c. It is
calculated exclude reserved regions in discontig.c.
2. If kernel code and data region is happen to be at the begin or the
end of physical memory, when min_low_pfn and max_low_pfn calculation is
bypassed kernel code and data, pages in initmem will report bad.
3. initrd is also in reserved regions, if it is at the begin or at the
end of physical memory, kernel will refuse to reuse the memory. Because
the virt_addr_valid check in free_initrd_mem.
So it is better to fix and clean up those issues.
Calculate min_low_pfn and max_low_pfn in a consistent way.
