2013-08-30drm/radeon/kms: fix up dce8 display watermark calc for dpmAlex Deucher

2013-08-30drm/radeon: default to 1024M gart size on rv770+Alex Deucher
Newer asics have a lot of vram so it's less of an issue to waste a little more space for the gart page table. This gives us some additional gart space before having to migrate to non-gart system ram for games, etc. where we use up most of vram. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: rework thermal state handlingAlex Deucher
1. Handle the the thermal state directly in the work handler. Remove the state selection function since nothing else uses it now. 2. On some asics there is no thermal state, so we just use a regular state and force the low performance state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: use multiple UVD power states (v3)Alex Deucher
Use the UVD handle information to determine which which power states to select when using UVD. For example, decoding a single SD stream requires much lower clocks than multiple HD streams. v2: switch to a cleaner dpm/uvd interface v3: change the uvd power state while streams are active if need be Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-08-30mtd: tests: introduce helper functionsAkinobu Mita
This introduces the helper functions which can be used by several mtd/tests modules. The following three functions are used all over the test modules. - mtdtest_erase_eraseblock() - mtdtest_scan_for_bad_eraseblocks() - mtdtest_erase_good_eraseblocks() The following are wrapper functions for mtd_read() and mtd_write() which can simplify the return value check. - mtdtest_read() - mtdtest_write() All helpers are put into a single .c file and it will be linked to every test module later. The code will actually be copied to every test module, but it is fine for our small test infrastructure.

2013-08-30Fix wrong flag ASSERT in xfs_attr_shortform_getvalueEric Sandeen
This ASSERT is testing an if_flags flag value against a di_aformat enum value. di_aformat is never assigned XFS_IFINLINE. This happens to work for now, because XFS_IFINLINE has the same value as XFS_DINODE_FMT_LOCAL, and that's tested just before we call this function. However, I think the intention is to assert that we have read in the data, i.e. XFS_IFINLINE on if_flags, before we use if_data. This is done in other places through the code as well.

2013-08-30tipc: set sk_err correctly when connection failsErik Hugne
Should a connect fail, if the publication/server is unavailable or due to some other error, a positive value will be returned and errno is never set. If the application code checks for an explicit zero return from connect (success) or a negative return (failure), it will not catch the error and subsequent send() calls will fail as shown from the strace snippet below. socket(0x1e /* PF_??? */, SOCK_SEQPACKET, 0) = 3 connect(3, {sa_family=0x1e /* AF_??? */, sa_data="\2\1\322\4\0\0\322\4\0\0\0\0\0\0"}, 16) = 111 sendto(3, "test", 4, 0, NULL, 0) = -1 EPIPE (Broken pipe) The reason for this behaviour is that TIPC wrongly inverts error codes set in sk_err.

2013-08-30tcp: tcp_make_synack() should use sock_wmallocPhil Oester
In commit 90ba9b19 (tcp: tcp_make_synack() can use alloc_skb()), Eric changed the call to sock_wmalloc in tcp_make_synack to alloc_skb. In doing so, the netfilter owner match lost its ability to block the SYNACK packet on outbound listening sockets. Revert the change, restoring the owner match functionality.

2013-08-30clk: fix new_parent dereference before null checkJames Hogan
Commit 71472c0 (clk: add support for clock reparent on set_rate) added a dereference of the new_parent pointer in clk_reparent(), but as detected by smatch clk_reparent() later checks whether new_parent is NULL. The dereference was in order to clear the new parent's new_child pointer to avoid duplicate POST_RATE_CHANGE notifications, so clearly isn't necessary if the new parent is NULL, so move it inside the "if (new_parent)" block.

2013-08-30bridge: separate querier and query timer into IGMP/IPv4 and MLD/IPv6 onesLinus Lüssing
Currently we would still potentially suffer multicast packet loss if there is just either an IGMP or an MLD querier: For the former case, we would possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is because we are currently assuming that if either an IGMP or MLD querier is present that the other one is present, too. This patch makes the behaviour and fix added in "bridge: disable snooping if there is no querier" (b00589af3b04) to also work if there is either just an IGMP or an MLD querier on the link: It refines the deactivation of the snooping to be protocol specific by using separate timers for the snooped IGMP and MLD queries as well as separate timers for our internal IGMP and MLD queriers.
