"MIPS: Calculate proper ebase value for 64-bit kernels"
9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp.
f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit
MIPS systems.
Before this we were using XKPHYS/cached as ebase and computed the uncached
xphsys/unchached address for that area. After that commit ebase became a
32-bit compat address and convert does not work anymore. We now should use
CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

For some combinations of PAGE_SIZE and vmbits, it is possible to have
userspace access that are beyond what is covered by the PGD, but within
vmbits. Such an access would cause the TLB refill handler to load garbage
values for PMD and PTE potentially giving userspace access to parts of the
physical address space to which it is not entitled.
In the TLB refill hot path, we add a single dsrl instruction so we can
check if any bits outside of the range covered by the PGD are set. In
the vmalloc side we then separate the bad case from the normal vmalloc
case and call tlb_do_page_fault_0 if warranted. This slows us down a
bit, but has the benefit of yielding deterministic behavior.
[Ralf: Fixed build error for 32-bit kernels.]

The MIPS implementation of die() forgets to call notify_die() and thus notifiers
registered via register_die_notifier() are not called. This results in kgdb not
being activated on exceptions.
The only subtlety is that notify_die declares its regs argument w/o const, so
the const had to be removed from mips die() as well.

Same issues as SD card detection: One of both is always triggering and the
handlers take care to shut it up and enable the other. To avoid messages
about "unbalanced interrupt enable/disable" they must not be automatically
enabled when initally requested.
This was not an issue with the db1200_defconfig due to fortunate timings;
on a build without network chip support the warnings appear.

In the 64-bit kernel we use swapper_pg_dir for three different things.
1) xuseg mappings for kernel threads.
2) vmap mappings for all kernel-space accesses in xkseg.
3) vmap mappings for kernel modules in ksseg (kseg2).
Due to how the TLB refill handlers work, any mapping established in
xkseg or ksseg will also establish a xuseg mapping that should never
be used by the kernel.
In order to be able to use exceptions to trap NULL pointer
dereferences, we need to ensure that nothing is mapped at address
zero. Since vmap mappings in xkseg are reflected in xuseg, this means
we need to ensure that there are no vmap mappings established at the
start of xkseg. So we move back VMALLOC_START to avoid establishing
vmap mappings at the start of xkseg.

The bypassing of this test is a leftover from 2.4 vintage

Currently KGDB uses probe_kernel_write() for all access to
memory via the KGDB core, so it can simply be deleted.
This fixes CVE-2010-1446.

On low memory boxes or those with highmem, kernel can OOM before the
background reclaims inodes via xfssyncd. Add a shrinker to run inode
reclaim so that it inode reclaim is expedited when memory is low.
This is more complex than it needs to be because the VM folk don't
want a context added to the shrinker infrastructure. Hence we need
to add a global list of XFS mount structures so the shrinker can
traverse them.

If dentry found stale happens to be a root of disconnected tree, we
can't d_drop() it; its d_hash is actually part of s_anon and d_drop()
would simply hide it from shrink_dcache_for_umount(), leading to

that.

zero padding length, such as AUTH HMACS parameter and CHUNKS

sk->sk_data_ready() of sctp socket can be called from both BH and non-BH
contexts, but the default sk->sk_data_ready(), sock_def_readable(), can
not be used in this case. Therefore, we have to make a new function
sctp_data_ready() to grab sk->sk_data_ready() with BH disabling.

[ INFO: possible irq lock inversion dependency detected ]
2.6.33-rc6 #129
---------------------------------------------------------
sctp_darn/1517 just changed the state of lock:
(clock-AF_INET){++.?..}, at: [<c06aab60>] sock_def_readable+0x20/0x80
but this lock took another, SOFTIRQ-unsafe lock in the past:
(slock-AF_INET){+.-...}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
1 lock held by sctp_darn/1517:
#0: (sk_lock-AF_INET){+.+.+.}, at: [<cdfe363d>] sctp_sendmsg+0x23d/0xc00 [sctp]

This reverts two commits:
fda48a0d7a8412cedacda46a9c0bf8ef9cd13559
tcp: bind() fix when many ports are bound
and a follow-on fix for it:
6443bb1fc2050ca2b6585a3fa77f7833b55329ed
ipv6: Fix inet6_csk_bind_conflict()
It causes problems with binding listening sockets when time-wait
sockets from a previous instance still are alive.
It's too late to keep fiddling with this so late in the -rc
series, and we'll deal with it in net-next-2.6 instead.

With CONFIG_NFS_V4 and data version 4, nfs_get_sb will allocate memory for
export_path in nfs4_validate_text_mount_data, so we need to free it then.
This is addressed in following kmemleak report:

ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has
been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the
tests in the bug reports below, Windows apparently uses [_MIN to _MAX].
Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location
descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it
doesn't matter which way we compute the end. But of course, there are
BIOSes that don't follow this rule, and we're better off if Linux handles
those exceptions the same way as Windows.
This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This
effectively reverts d558b483d5 and 03db42adfe and replaces them with
simpler code.
