FUJITA Tomonori e88a39dee1 x86: pci-gart fix
map_sg could copy the last sg element to another position (if merging
some elements). It breaks sg chaining. This copies only
dma_address/length instead of the whole sg element.

Tejun Heo edc9305284 ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2
P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.

When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears.  Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.

This patch implements workaround for the board.  If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.

This workaround fixes bugzilla #8923.

Tejun Heo 0e06d9ce7a libata: cosmetic clean up in ata_eh_reset()
Local variable @action usage in ata_eh_reset() is a bit confusing.
It's used only to cache ehc->i.action to test reset masks after
clearing it; however, due to the generic name "action", it's easy to
misinterpret the local variable as containing the selected reset
method later.  Also, the reason for caching the original value is easy
to miss.

This patch renames @action to @tmp_action and make it buffer newly
selected value instead to improve readability.

Peter Williams e1d1484f72 sched: reduce balance-tasks overhead
At the moment, balance_tasks() provides low level functionality for both
  move_tasks() and move_one_task() (indirectly) via the load_balance()
function (in the sched_class interface) which also provides dual
functionality.  This dual functionality complicates the interfaces and
internal mechanisms and makes the run time overhead of operations that
are called with two run queue locks held.

This patch addresses this issue and reduces the overhead of these
operations.

"scheduling while atomic" message more helpful. Use show_regs() instead

why this function was called) so show_regs()'s atomicity expectations
are guaranteed.

Milton Miller 7378547f2c sched: fix sched_domain sysctl registration again
commit  029190c515 (cpuset
sched_load_balance flag) was not tested SCHED_DEBUG enabled as
committed as it dereferences NULL when used and it reordered
the sysctl registration to cause it to never show any domains
or their tunables.

Fixes:

1) restore arch_init_sched_domains ordering
	we can't walk the domains before we build them

	presently we register cpus with empty directories (no domain
	directories or files).

2) make unregister_sched_domain_sysctl do nothing when already unregistered
	detach_destroy_domains is now called one set of cpus at a time
	unregister_syctl dereferences NULL if called with a null.

	While the the function would always dereference null if called
	twice, in the previous code it was always called once and then
	was followed a register.  So only the hidden bug of the
	sysctl_root_table not being allocated followed by an attempt to
	free it would have shown the error.

3) always call unregister and register in partition_sched_domains
	The code is "smart" about unregistering only needed domains.
	Since we aren't guaranteed any calls to unregister, always 
	unregister.   Without calling register on the way out we
	will not have a table or any sysctl tree.

4) warn if register is called without unregistering
	The previous table memory is lost, leaving pointers to the
	later freed memory in sysctl and leaking the memory of the
	tables.

Before this patch on a 2-core 4-thread box compiled for SMT and NUMA,
the domains appear empty (there are actually 3 levels per cpu).  And as
soon as two domains a null pointer is dereferenced (unreliable in this
case is stack garbage):

Gerrit Renker 24c667db59 [CCID2/3]: Initialisation assignments of 0 are redundant
Assigning initial values of `0' is redundant when loading a new CCID structure,
since in net/dccp/ccid.c the entire CCID structure is zeroed out prior to
initialisation in ccid_new():

    	struct ccid {
    		struct ccid_operations *ccid_ops;
    		char		       ccid_priv[0];
    	};

    	// ...
    	if (rx) {
    		memset(ccid + 1, 0, ccid_ops->ccid_hc_rx_obj_size);
    		if (ccid->ccid_ops->ccid_hc_rx_init != NULL &&
    		    ccid->ccid_ops->ccid_hc_rx_init(ccid, sk) != 0)
    			goto out_free_ccid;
    	} else {
    		memset(ccid + 1, 0, ccid_ops->ccid_hc_tx_obj_size);
    		/* analogous to the rx case */
    	}

This patch therefore removes the redundant assignments. Thanks to Arnaldo for
the inspiration.

Gerrit Renker d8ef2c29a0 [DCCP]: Convert Reset code into socket error number
This adds support for converting the 11 currently defined Reset codes into system
error numbers, which are stored in sk_err for further interpretation.

This makes the externally visible API behaviour similar to TCP, since a client
connecting to a non-existing port will experience ECONNREFUSED.

* Code 0, Unspecified, is interpreted as non-error (0);
* Code 1, Closed (normal termination), also maps into 0;
* Code 2, Aborted, maps into "Connection reset by peer" (ECONNRESET);
* Code 3, No Connection and
  Code 7, Connection Refused, map into "Connection refused" (ECONNREFUSED);
* Code 4, Packet Error, maps into "No message of desired type" (ENOMSG);
* Code 5, Option Error, maps into "Illegal byte sequence" (EILSEQ);
* Code 6, Mandatory Error, maps into "Operation not supported on transport endpoint" (EOPNOTSUPP);
* Code 8, Bad Service Code, maps into "Invalid request code" (EBADRQC);
* Code 9, Too Busy, maps into "Too many users" (EUSERS);
* Code 10, Bad Init Cookie, maps into "Invalid request descriptor" (EBADR);
* Code 11, Aggression Penalty, maps into "Quota exceeded" (EDQUOT)
  which makes sense in terms of using more than the `fair share' of bandwidth.

Gerrit Renker 1238d0873b [DCCP]: One more exemption from full sequence number checks
This fixes the following problem: client connects to peer which has no DCCP
enabled or loaded; ICMP error messages ("Protocol Unavailable") can be seen
on the wire, but the application hangs. Reason: ICMP packets don't get through
to dccp_v4_err.

When reporting errors, a sequence number check is made for the DCCP packet
that had caused an ICMP error to arrive.
Such checks can not be made if the socket is in state LISTEN, RESPOND (which
in the implementation is the same as LISTEN), or REQUEST, since update_gsr()
has not been called in these states, hence the sequence window is 0..0.

This patch fixes the problem by adding the REQUEST state as another exemption
to the window check. The error reporting now works as expected on connecting.

Jens Axboe 642f149031 SG: Change sg_set_page() to take length and offset argument
Most drivers need to set length and offset as well, so may as well fold
those three lines into one.

Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

Haavard Skinnemoen 18ccc41943 AVR32: Fix sg_page breakage
The latest sg changes introduce the following build errors on AVR32:

include/asm/dma-mapping.h: In function ‘dma_map_sg’:
include/asm/dma-mapping.h:220: error: implicit declaration of function ‘sg_page’
include/asm/dma-mapping.h:220: error: invalid operands to binary -
include/asm/dma-mapping.h:221: error: implicit declaration of function ‘sg_virt’
include/asm/dma-mapping.h:221: warning: assignment makes pointer from integer without a cast
include/asm/dma-mapping.h: In function ‘dma_sync_sg_for_device’:
include/asm/dma-mapping.h:330: warning: passing argument 2 of ‘dma_cache_sync’ makes pointer from integer without a cast

Fix it by including the correct header file, i.e. linux/scatterlist.h
instead of asm/scatterlist.h.

Chris Wright d58aa8c7b1 [SPARC64]: pass correct addr in get_fb_unmapped_area(MAP_FIXED)
Looks like the MAP_FIXED case is using the wrong address hint.  I'd
expect the comment "don't mess with it" means pass the request
straight on through, not change the address requested to -ENOMEM.

Pavel Emelyanov 03cf786c4e [IPV4]: Explicitly call fib_get_table() in fib_frontend.c
In case the "multiple tables" config option is y, the ip_fib_local_table
is not a variable, but a macro, that calls fib_get_table(RT_TABLE_LOCAL).

Some code uses this "variable" *3* times in one place, thus implicitly
making 3 calls. Fix it.
