ARM: OMAP: CLKFW: Initial debugfs support for omap clock framework
debugfs can provide the infrastructure to trace the dependencies of
clock tree hierarchy quite visibly. This patch enables to keep track
of clock tree hierarchy and expose their attributes under each clock
directry as below:
Although, compared with David Brownell's small patch, this may look
bit overkilling, I expect that this debugfs can deal with other PRCM
complexities at the same time. For example, powerdomain dependencies
can be expressed by using symbolic links of these clocks if
powerdomain supports dubgfs as well.

Fix memory corruption and crash on 32-bit x86 systems.
If a !PAE x86 kernel is booted on a 32-bit system with more than 4GB of
RAM, then we call memory_present() with a start/end that goes outside
the scope of MAX_PHYSMEM_BITS.
That causes this loop to happily walk over the limit of the sparse
memory section map:
for (pfn = start; pfn < end; pfn += PAGES_PER_SECTION) {
unsigned long section = pfn_to_section_nr(pfn);
struct mem_section *ms;
ms = __nr_to_section(section);
if (!ms->section_mem_map)
ms->section_mem_map = sparse_encode_early_nid(nid) |
SECTION_MARKED_PRESENT;
'ms' will be out of bounds and we'll corrupt a small amount of memory by
encoding the node ID and writing SECTION_MARKED_PRESENT (==0x1) over it.
The corruption might happen when encoding a non-zero node ID, or due to
the SECTION_MARKED_PRESENT which is 0x1:
mmzone.h:#define SECTION_MARKED_PRESENT (1UL<<0)
The fix is to sanity check anything the architecture passes to
sparsemem.
This bug seems to be rather old (as old as sparsemem support itself),
but the exact incarnation depended on random details like configs, which
made this bug more prominent in v2.6.25-to-be.
An additional enhancement might be to print a warning about ignored or
trimmed memory ranges.

rfkill: Fix device type check when toggling states
rfkill_switch_all() is supposed to only switch all the interfaces of a
given type, but does not actually do this; instead, it just switches
everything currently in the same state.
Add the necessary type check in.
(This fixes a bug I've been seeing while developing an rfkill laptop
driver, with both bluetooth and wireless simultaneously changing state
after only pressing either KEY_WLAN or KEY_BLUETOOTH).

ssb: Fix usage of struct device used for DMAing
This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.
Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.

netconsole: only set CON_PRINTBUFFER if the user specifies a netconsole
Since 0bcc1816188e570bde1d56a208996660f2633ae0 (netconsole: Support
dynamic reconfiguration using configfs), the netconsole is always
registered, regardless of whether the user actually specified a
netconsole configuration on the command line.
However because netconsole has CON_PRINTBUFFER set, when it is
registered it causes the printk buffer to be replayed to all consoles.
When there is no netconsole configured this is a) pointless, and b)
somewhat annoying for the user of the existing console.
So instead we should only set CON_PRINTBUFFER if there is a netconsole
configuration found on the command line. This retains the existing
behaviour if a netconsole is setup by the user, and avoids spamming
other consoles when we're only registering for the dynamic
netconsole case.

pruned . This can lead to tcp deadlock state if the next two

1. There are a sequence hole between last received in

2. Size of all segments in the out-of-order queue is more than tcp_mem[2].

The page offset is miscalculated, leading to corruption of the fragment
lists and subsequently to memory corruption and panics.
[ Side note: the bug is a fairly direct result of the naming. Nick was
likely misled by the use of "offs", since we tend to use the notion of
"offset" not as an absolute position, but as an offset _within_ a page
or allocation.
Alternatively, a "pgoff_t" is a page index, but not a byte offset -
our VM naming can be a bit confusing.
So in this case, a VM person would likely have called this a "pos",
not an "offs", or perhaps talked about byte offsets rather than page
offsets (since it's counted in bytes, not pages). - Linus ]
TC_H_MAJ(parentid) for root classes is the same as for ingress, and if
ingress qdisc is created qdisc_lookup() returns its pointer (without
ingress NULL is returned). After this all qdisc_lookups give the same,
and we get endless loop. (I don't know how this could hide for so long
- it should trigger with every leaf class deleted if it's qdisc isn't
empty.)
After this fix qdisc_lookup() is omitted both for ingress and root
parents, but looking for root is only wasting a little time here...

locks: fix possible infinite loop in fcntl(F_SETLKW) over nfs
Miklos Szeredi found the bug:
"Basically what happens is that on the server nlm_fopen() calls
nfsd_open() which returns -EACCES, to which nlm_fopen() returns
NLM_LCK_DENIED.
"On the client this will turn into a -EAGAIN (nlm_stat_to_errno()),
which in will cause fcntl_setlk() to retry forever."
So, for example, opening a file on an nfs filesystem, changing
permissions to forbid further access, then trying to lock the file,
could result in an infinite loop.
And Trond Myklebust identified the culprit, from Marc Eshel and I:
That commit claimed to just be reshuffling code, but actually introduced
a behavioral change by calling the lock method repeatedly as long as it
returned -EAGAIN.
We assumed this would be safe, since we assumed a lock of type SETLKW
would only return with either success or an error other than -EAGAIN.
However, nfs does can in fact return -EAGAIN in this situation, and
independently of whether that behavior is correct or not, we don't
actually need this change, and it seems far safer not to depend on such
assumptions about the filesystem's ->lock method.
Therefore, revert the problematic part of the original commit. This
leaves vfs_lock_file() and its other callers unchanged, while returning
fcntl_setlk and fcntl_setlk64 to their former behavior.

[BRIDGE]: Fix crash in __ip_route_output_key with bridge netfilter
The bridge netfilter code attaches a fake dst_entry with a pointer to a
fake net_device structure to skbs it passes up to IPv4 netfilter. This
leads to crashes when the skb is passed to __ip_route_output_key when
dereferencing the namespace pointer.
Since bridging can currently only operate in the init_net namespace,
the easiest fix for now is to initialize the nd_net pointer of the
fake net_device struct to &init_net.

CPU1: CPU2:
clusterip_config_entry_put: clusterip_config_find_get:

which is a) not in list b) has a stale dev pointer.
The problems will happen when the CPU2 will release the entry - it
will remove it from the list for the 2nd time, thus spoiling it, and
will put a stale dev pointer.

consists only of 1-byte next-header field and 1-byte length
