mtd: edit comments on deprecation of ioctl ECCGETLAYOUT
There were some improvements and additions necessary in the
comments explaining of the expansion of nand_ecclayout, the
introduction of nand_ecclayout_user, and the deprecation of the
ioctl ECCGETLAYOUT.
Also, I found a better placement for the macro MTD_MAX_ECCPOS_ENTRIES;
next to the definition of MTD_MAX_OOBFREE_ENTRIES in mtd-abi.h. The macro
is really only important for the ioctl code (found in drivers/mtd/mtdchar.c)
but since there are small edits being made to the user-space header, I
figured this is a better location.

mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUT
struct nand_ecclayout is too small for many new chips; OOB regions can be as
large as 448 bytes and may increase more in the future. Thus, copying that
struct to user-space with the ECCGETLAYOUT ioctl is not a good idea; the ioctl
would have to be updated every time there's a change to the current largest
size.
Instead, the old nand_ecclayout is renamed to nand_ecclayout_user and a
new struct nand_ecclayout is created that can accomodate larger sizes and
expand without affecting the user-space. struct nand_ecclayout can still
be used in board drivers without modification -- at least for now.
A new function is provided to convert from the new to the old in order to
allow the deprecated ioctl to continue to work with truncated data. Perhaps
the ioctl, the conversion process, and the struct nand_ecclayout_user can be
removed altogether in the future.
Note: There are comments in nand/davinci_nand.c::nand_davinci_probe()
regarding this issue; this driver (and maybe others) can be updated to
account for extra space. All kernel drivers can use the expanded
nand_ecclayout as a drop-in replacement and ignore its benefits.

Furthermore, all prior callers of the function made sure they're

In the same spirit, the .get_wol handler shouldn't indicate support

RDMA/cxgb3: Turn off RX coalescing for iWARP connections
The HW by default has RX coalescing on. For iWARP connections, this
causes a 100ms delay in connection establishement due to the ingress
MPA Start message being stalled in HW. So explicitly turn RX
coalescing off when setting up iWARP connections.
This was causing very bad performance for NP64 gather operations using

The PL310 on the ct-ca9x4 tile for the Versatile Express does not need

the boot monitor sets this up for an 8-cycle delay on reads and writes,

x86: Avoid 'constant_test_bit()' misoptimization due to cast to non-volatile
While debugging bit_spin_lock() hang, it was tracked down to gcc-4.4
misoptimization of non-inlined constant_test_bit() due to non-volatile
addr when 'const volatile unsigned long *addr' cast to 'unsigned long *'
with subsequent unconditional jump to pause (and not to the test) leading
to hang.
Compiling with gcc-4.3 or disabling CONFIG_OPTIMIZE_INLINING yields inlined
constant_test_bit() and correct jump, thus working around the kernel bug.
Other arches than asm-x86 may implement this slightly differently;
2.6.29 mitigates the misoptimization by changing the function prototype
(commit
c4295fbb6048d85f0b41c5ced5cbf63f6811c46c) but probably fixing the issue

Compex FreedomLine 32 PnP-PCI2 cards have only TP and BNC connectors but the

Connecting TP back generates LinkPass interrupt but de_media_interrupt() is
broken - it only updates the link state of currently connected media, ignoring
the fact that LinkPass and LinkFail bits of MacStatus register belong to the
TP port only (the chip documentation says that).
This patch changes de_media_interrupt() to switch media to TP when link goes
up (and media type is not locked) and also to update the link state only when
the TP port is used.

ARM: pxa168fb: clear enable bit when not active
While fb isn't active, we should clear CFG_GRA_ENA bit. The existing code
can't clear this bit.

arch/tile: remove dead code from intvec_32.S
This "bpt_code" instruction was killed off in our development line a while
ago (the actual definition of bpt_code that is used is in kernel/traps.c)
but I didn't push it for 2.6.36 because it seemed harmless and I didn't
want to try to push more than absolutely necessary.
However, we recently fixed a bug in our gcc that had been causing
"-gdwarf2" not to be passed to the assembler, and passing this flag causes
an erroneous assembler failure in the presence of code in a data section,
sometimes. While we'd like to track down the bug in the assembler,
we'd also like to make sure 2.6.36 builds with the current toolchain,
so I'm removing this dead code as well.

fremap: get rid of broken 'end' variable
Thomas Pollet points out that the 'end' variable is broken. It was
computed based on start/size before they were page-aligned, and as such
doesn't actually match any of the other actions we take. The overflow
test on end was also redundant, since we had already tested it with the
properly aligned version.
So just get rid of it entirely. The one remaining use for that broken
variable can just use 'start+size' like all the other cases already did.
