The single entry is important because when we bring up secondary\ncores they need to ensure any data structure they need to access (eg\nPACA or stack) is always mapped.\n\nSo we really need to determine what size will actually be mapped by the\nfirst TLB entry to ensure we limit early memory references to that\nregion. We refactor the map_mem_in_cams() code to provider a helper\nfunction that we can utilize to determine the size of the first TLB\nentry while taking into account size and alignment

The\nevent code 0x180032 should be used to count events on thread 0 and 1. The\npatch fixes the event code for the L1 cache write.\n\nFYI, the documentation lists three event codes for the L1 cache read event\nand three event codes for the L1 cache write event. The event description\nfor the event codes is as follows:\n\nL1 cache read requests 0x80082 LSU 0 only\nL1 cache read requests 0x8008A LSU 1 only\nL1 cache read requests 0x80030 LSU 1 or LSU 0, counter 2 only.\n\nL1 cache store requests 0x80086 LSU 0 only\nL1 cache store requests 0x8008E LSU 1 only\nL1 cache store requests 0x80032 LSU 0 or LSU 1, counter 1 only.\n\nThere can only be one request from either LSU 0 or 1 active at a time.\n\nSigned-off-by: Carl Love \u003ccel@us.ibm.com\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "e69b742a6793dc5bf16f6eedca534d4bc10d68b2", "tree": "63765003b6dcffd410d82e3ea2ecd10153596570", "parents": [ "66857b3a9e88ac6f6e279eaa06b84367e662c0dd" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Sep 26 19:37:57 2011 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Sep 29 17:02:04 2011 +1000" }, "message": "powerpc/ptrace: Fix build with gcc 4.6\n\ngcc (rightfully) complains that we are accessing beyond the\nend of the fpr array (we do, to access the fpscr).\n\nThe only sane thing to do (whether anything in that code can be\ncalled remotely sane is debatable) is to special case fpscr and\nhandle it as a separate statement.\n\nI initially tried to do it it by making the array access conditional\nto index \u003c PT_FPSCR and using a 3rd else leg but for some reason gcc\nwas unable to understand it and still spewed the warning.\n\nSo I ended up with something a tad more intricated but it seems to\nbuild on 32-bit and on 64-bit with and without VSX.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "66857b3a9e88ac6f6e279eaa06b84367e662c0dd", "tree": "beae75afef05fc761d338f3ec9d238d60ffa4008", "parents": [ "bb36c44557a4fcbaa17c0f2776e12a05a691b432" ], "author": { "name": "Jimi Xenidis", "email": "jimix@pobox.com", "time": "Fri Sep 23 05:40:46 2011 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Sep 29 16:58:22 2011 +1000" }, "message": "powerpc: Fix xmon for systems without MSR[RI]\n\nBased on patch by David Gibson \u003cdwg@au1.ibm.com\u003e\n\nxmon has a longstanding bug on systems which are SMP-capable but lack\nthe MSR[RI] bit.

When encounter a MSE event, set ep-\u003eskip flag, update event ring\n dequeue pointer and return.\n\n2. When encounter the next event on this ep, the driver will run the\n do-while loop, fetch td from ep\u0027s td_list to find the td\n corresponding to this event. All tds missed are marked as short\n transfer(-EXDEV).\n\nThe do-while loop will end in two ways:\n\n1. If the td pointed by the event trb is found;\n\n2. If the ep ring\u0027s td_list is empty.\n\nHowever, if a buggy HW reports some unpredicted event (for example, an\noverrun event following a MSE event while the ep ring is actually not\nempty), the driver will never find the td, and it will loop until the\ntd_list is empty.\n\nUnfortunately, the spinlock is dropped when give back a urb in the\ndo-while loop. During the spinlock released period, the class driver\nmay still submit urbs and add tds to the td_list. This may cause\ndisaster, since the td_list will never be empty and the loop never ends,\nand the system hangs.\n\nTo fix this, count the number of TDs on the ep ring before skipping TDs,\nand quit the loop when skipped that number of tds.

This causes the xHCI host controller to\nissue a warm port reset, which doesn\u0027t finish before the USB core times\nout while waiting for it to complete.\n\nWhen the warm port reset does complete, and the xHC gives back a port\nstatus change event, the xHCI driver kicks khubd. However, it fails to\nset the bit indicating there is a change event for that port because the\nlogic in xhci-hub.c doesn\u0027t check for the warm port reset bit.\n\nAfter that, the warm port status change bit is never cleared by the USB\ncore, and the xHC stops reporting port status change bits. (The xHCI\nspec says it shouldn\u0027t report more port events until all change bits are\ncleared.) This means any port changes when a new device is connected\nwill never be reported, and the port will seem \"dead\" until the xHCI\ndriver is unloaded and reloaded, or the computer is rebooted. Fix this\nby making the xHCI driver set the port change bit when a warm port reset\nchange bit is set.\n\nA better solution would be to make the USB core handle warm port reset\nin differently, merging the current code with the standard port reset\ncode that does an incremental backoff on the timeout, and tries to\ncomplete the port reset two more times before giving up. That more\ncomplicated fix will be merged next window, and this fix will be\nbackported to stable.\n\nThis should be backported to kernels as old as 3.0, since that was the\nfirst kernel with commit a11496ebf375 (\"xHCI: warm reset support\").\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c19cc78efe922e86da7ba694dbfc4be066dd7eb4", "tree": "ac4322e33743be3f12ca6b7c2fa8085911138d7c", "parents": [ "58c3c3aa01b455ecb99d61ce73f1444274af696b" ], "author": { "name": "Randy Dunlap", "email": "rdunlap@xenotime.net", "time": "Mon Sep 19 16:05:10 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 19 17:15:46 2011 -0700" }, "message": "staging: fix comedi build when ISA_DMA_API is enabled but COMEDI_PCI is not enabled\n\nFix build when CONFIG_ISA_DMA_API is enabled but\nCONFIG_COMEDI_PCI[_DRIVERS] is not enabled.\n\nFixes these build errors:\n\n drivers/staging/comedi/drivers/ni_labpc.c: In function \u0027labpc_ai_cmd\u0027:\n drivers/staging/comedi/drivers/ni_labpc.c:1351: error: implicit declaration of function \u0027labpc_suggest_transfer_size\u0027\n drivers/staging/comedi/drivers/ni_labpc.c: At top level:\n drivers/staging/comedi/drivers/ni_labpc.c:1802: error: conflicting types for \u0027labpc_suggest_transfer_size\u0027\n drivers/staging/comedi/drivers/ni_labpc.c:1351: note: previous implicit declaration of \u0027labpc_suggest_transfer_size\u0027 was here\n\nSigned-off-by: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "58c3c3aa01b455ecb99d61ce73f1444274af696b", "tree": "0c79541bfd948b06923780d8c651e83b1b6b5822", "parents": [ "1a51410abe7d0ee4b1d112780f46df87d3621043" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 19 17:10:57 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 19 17:10:57 2011 -0700" }, "message": "Make taskstats round statistics down to nearest 1k bytes/events\n\nEven with just the interface limited to admin, there really is little to\nreason to give byte-per-byte counts for taskstats.
