2013-06-20clk: nomadik: implement the Nomadik clocks properlyLinus Walleij
The Nomadik clock implementation was a stub just using fixed clocks. This implements the clocks properly instead of relying on them all being on at boot and leaving them all on. The PLLs are on the top locking to the main chrystal oscillator, then the HCLK for the peripherals are below PLL2. The gated clocks are implemented with zero cells and given the clock ID as a property of each node, so every gate need to have its own node in the device tree. This is because the gate registers contain both HCLK gates and PCLK gates, where the latter has HCLK as parent. As can be seen from the register layout, this is a complete mixup, which means all these gates need their own node to properly model parent/child relations for PCLKs apart from the HCLKs. This driver also adds a helpful debugfs file to inspect the hardware state of the clock gates. This is the end result in <debugfs>/clk/clk_summary after applying a proper device tree: ulpiclk 0 0 60000000 mxtal 3 3 19200000 pll2 1 1 864000000 clk48 3 3 48000000 rngcclk 1 1 48000000 usbmclk 0 0 48000000 mshcclk 0 0 48000000 mspclk3 0 0 48000000 x3dclk 0 0 48000000 skeclk 0 0 48000000 owmclk 0 0 48000000 mspclk2 0 0 48000000 mspclk1 0 0 48000000 uart2clk 0 0 48000000 ipbmcclk 0 0 48000000 ipi2cclk 0 0 48000000 usbclk 0 0 48000000 mspclk0 0 0 48000000 uart1clk 1 2 48000000 i2c1clk 0 0 48000000 i2c0clk 0 0 48000000 sdiclk 1 1 48000000 uart0clk 0 0 48000000 sspiclk 0 0 48000000 irdaclk 0 0 48000000 clk72 0 0 72000000 difclk 0 0 72000000 clcdclk 0 0 72000000 clk216 0 0 216000000 hsiclkrx 0 0 216000000 clk108 0 0 108000000 hsiclktx 0 0 108000000 clk27 0 0 27000000 pll1 1 1 264000000 hclk 3 3 264000000 hclkrng 1 1 264000000 hclkusbm 0 0 264000000 hclkcryp 0 0 264000000 hclkhash 0 0 264000000 hclk3d 0 0 264000000 hclkhpi 0 0 264000000 hclksva 0 0 264000000 hclksaa 0 0 264000000 hclkdif 0 0 264000000 hclkusb 0 0 264000000 hclkclcd 0 0 264000000 hclkdma1 0 0 264000000 hclksdram 0 0 264000000 hclksmc 1 1 264000000 hclkdma0 0 0 264000000 pclk 7 9 264000000 pclkmsp3 0 0 264000000 pclkmshc 0 0 264000000 pclkhsem 0 0 264000000 pclkske 0 0 264000000 pclkowm 0 0 264000000 pclkmsp2 0 0 264000000 pclkmsp1 0 0 264000000 pclkuart2 0 0 264000000 pclkxti 0 0 264000000 pclkhsi 0 0 264000000 pclkmsp0 0 0 264000000 pclkuart1 1 1 264000000 pclki2c1 0 0 264000000 pclki2c0 0 0 264000000 pclksdi 1 1 264000000 pclkuart0 1 1 264000000 pclkssp 0 0 264000000 pclkirda 0 0 264000000 timclk 1 1 2400000 Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-20powerpc/vfio: Implement IOMMU driver for VFIOAlexey Kardashevskiy
VFIO implements platform independent stuff such as a PCI driver, BAR access (via read/write on a file descriptor or direct mapping when possible) and IRQ signaling. The platform dependent part includes IOMMU initialization and handling. This implements an IOMMU driver for VFIO which does mapping/unmapping pages for the guest IO and provides information about DMA window (required by a POWER guest).

2013-06-19tracing: Disable tracing on warningSteven Rostedt (Red Hat)
Add a traceoff_on_warning option in both the kernel command line as well as a sysctl option. When set, any WARN*() function that is hit will cause the tracing_on variable to be cleared, which disables writing to the ring buffer. This is useful especially when tracing a bug with function tracing. When a warning is hit, the print caused by the warning can flood the trace with the functions that producing the output for the warning. This can make the resulting trace useless by either hiding where the bug happened, or worse, by overflowing the buffer and losing the trace of the bug totally.

2013-06-19tracing: Update documentation on tracepoint glob matchingSteven Rostedt (Red Hat)
b0f1a59a "tracing/filters: Use a different op for glob match" added glob matching to tracepoint filter strings. It uses the ftrace function tracing glob matching facility that allows for the wild card character (*) to be used at the start and/or end of the matching string. But the documentation still states that the filtering only allows for exact string matches. Cc: Li Zefan <lizefan@huawei.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-06-19tracing: Add binary '&' filter for eventsSteven Rostedt
There are some cases when filtering on a set flag of a field of a tracepoint is useful. But currently the only filtering commands for numbered fields is ==, !=, <, <=, >, >=. This does not help when you just want to trace if a specific flag is set. For example: > # sudo trace-cmd record -e brcmfmac:brcmf_dbg -f 'level & 0x40000' > disable all > enable brcmfmac:brcmf_dbg > path = /sys/kernel/debug/tracing/events/brcmfmac/brcmf_dbg/enable > (level & 0x40000) > ^ > parse_error: Invalid operator > When trying to trace brcmf_dbg when level has its 1 << 18 bit set, the filter fails to perform. By allowing a binary '&' operation, this gives the user the ability to test a bit. Note, a binary '|' is not added, as it doesn't make sense as fields must be compared to constants (for now), and ORing a constant will always return true.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-17tipc: change socket buffer overflow control to respect sk_rcvbufYing Xue
As per feedback from the netdev community, we change the buffer overflow protection algorithm in receiving sockets so that it always respects the nominal upper limit set in sk_rcvbuf. Instead of scaling up from a small sk_rcvbuf value, which leads to violation of the configured sk_rcvbuf limit, we now calculate the weighted per-message limit by scaling down from a much bigger value, still in the same field, according to the importance priority of the received message. To allow for administrative tunability of the socket receive buffer size, we create a tipc_rmem sysctl variable to allow the user to configure an even bigger value via sysctl command. It is a size of three (min/default/max) to be consistent with things like tcp_rmem. By default, the value initialized in tipc_rmem[1] is equal to the receive socket size needed by a TIPC_CRITICAL_IMPORTANCE message. This value is also set as the default value of sk_rcvbuf.
