2009-01-07oprofile: remove #ifdef CONFIG_OPROFILE_IBS in non-ibs codeRobert Richter
The ifdefs can be removed since the code is no longer ibs specific and can be used for other purposes as well. IBS specific code is only in op_model_amd.c. Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07ring_buffer: fix ring_buffer_event_length()Robert Richter
Function ring_buffer_event_length() provides an interface to detect the length of data stored in an entry. However, the length contains offsets depending on the internal usage. This makes it unusable. This patch fixes this and now ring_buffer_event_length() returns the alligned length that has been used in ring_buffer_lock_reserve(). Cc: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07oprofile: use new data sample format for ibsRobert Richter
The new ring buffer implementation allows the storage of samples with different size. This patch implements the usage of the new sample format to store ibs samples in the cpu buffer. Until now, writing to the cpu buffer could lead to incomplete sampling sequences since IBS samples were transfered in multiple samples. Due to a full buffer, data could be lost at any time. This can't happen any more since the complete data is reserved in advance and then stored in a single sample. Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07oprofile: add op_cpu_buffer_get_data()Robert Richter
This function provides access to attached data of a sample. It returns the size of data including the current value. Also, op_cpu_buffer_get_size() is available to check if there is data attached. Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07oprofile: add op_cpu_buffer_add_data()Robert Richter
This function can be used to attach data to a sample. It returns the remaining free buffer size that has been reserved with op_cpu_buffer_write_reserve(). Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07oprofile: rework implementation of cpu buffer eventsRobert Richter
Special events such as task or context switches are marked with an escape code in the cpu buffer followed by an event code or a task identifier. There is one escape code per event. To make escape sequences also available for data samples the internal cpu buffer format must be changed. The current implementation does not allow the extension of event codes since this would lead to collisions with the task identifiers. To avoid this, this patch introduces an event mask that allows the storage of multiple events with one escape code. Now, task identifiers are stored in the data section of the sample. The implementation also allows the usage of custom data in a sample. As a side effect the new code is much more readable and easier to understand.

2009-01-07oprofile: modify op_cpu_buffer_read_entry()Robert Richter
This implements the support of samples with attached data. Signed-off-by: Robert Richter <robert.richter@amd.com>
2009-01-07oprofile: add op_cpu_buffer_write_reserve()Robert Richter
This function prepares the cpu buffer to write a sample. Struct op_entry is used during operations on the ring buffer while struct op_sample contains the data that is stored in the ring buffer. Struct entry can be uninitialized. The function reserves a data array that is specified by size. Use op_cpu_buffer_write_commit() after preparing the sample. In case of errors a null pointer is returned, otherwise the pointer to the sample. Signed-off-by: Robert Richter <robert.richter@amd.com>

Andrew Vaszquez said: > There's a problem that is causing commands returned by the LLD with > a DID_RESET status to be reissued with cleared cmd->sdb data which > in our tests are manifesting in firmware detected overruns. Here's > a snippet of a READ_10 scsi_cmnd upon completion by the storage The problem is caused by: commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce Author: Alan Stern <stern@rowland.harvard.edu> Date: Mon Nov 3 15:56:47 2008 -0500 [SCSI] simplify scsi_io_completion() Because scsi_release_buffers() is called before commands that go through the ACTION_RETRY and ACTION_DELAYED_RETRY legs are requeued. However, they're not re-prepared, so nothing ever reallocates the buffer resources to them. Fix this by releasing the buffers only if we're not going to go down these legs (but scsi_release_buffers() on all legs including two in scsi_end_request(); this latter needs a special version __scsi_release_buffers() because the final one can be called after the request has been freed, so the bidi test in scsi_release_buffers(), which touches the request has to be skipped).

2009-01-07kbuild: add a symlink to the source for separate objdirsAndi Kleen
I have some scripts which need to map back to the source directory from an objdir.

2009-01-07kconfig: add script to manipulate .config files on the command lineAndi Kleen
I often change single options in .config files. Instead of using an editor or one of the frontends it's convenient to do this from the command line. It's also useful to do from automated build scripts when building different variants from a base config file. I extracted most of the CONFIG manipulation code from one of my build scripts into a new shell script scripts/config The script is not integrated with the normal Kconfig machinery and doesn't do any checking against Kconfig files, but just manipulates that text format. This is always done at make time anyways. I believe this script would be a useful standard addition for scripts/* Sample usage: ./scripts/config --disable smp Disable SMP in .config file ./scripts/config --file otherdir/.config --module e1000e Enable E1000E as module in otherdir/.config ./scripts/config --state smp y Check state of config option CONFIG_SMP After merging into git please make scripts/config executable Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2009-01-07bootchart: improve output based on Dave Jones' feedbackArjan van de Ven
Dave Jones, in his blog, had some feedback about the bootchart script: Primarily his complaint was that shorter delays weren't visualized. The reason for that was that too small delays will have their labels mixed up in the graph in an unreadable mess. This patch has a fix for this; for one, it makes the output wider, so more will fit. The second part is that smaller delays are now shown with a much smaller font for the label; while this isn't per se readable at a 1:1 zoom, at least you can zoom in with most SVG viewing applications and see what it is you are looking at.

2009-01-07fix modules_install via NFSSam Ravnborg
Rafael reported: I get the following error from 'make modules_install' on my test boxes: HOSTCC firmware/ihex2fw /home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system compilation terminated. make[3]: *** [firmware/ihex2fw] Error 1 make[2]: *** [_modinst_post] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 where the configuration is that the kernel is compiled on a build box with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by each test box (full path to this directory is the same on the build box and on the test boxes). Then, I cd into <destdir>, run 'make modules_install' and get the error above. The issue turns out to be that we when we install firmware pick up the list of firmware blobs from firmware/Makefile. And this triggers the Makefile rules to update ihex2fw. There were two solutions for this issue: 1) Move the list of firmware blobs to a separate file 2) Avoid ihex2fw rebuild by moving it to scripts As I seriously beleive that the list of firmware blobs should be done in a fundamental different way solution 2) was selected.

2009-01-07nfsd: fix double-locks of directory mutexJ. Bruce Fields
A number of nfsd operations depend on the i_mutex to cover more code than just the fsync, so the approach of 4c728ef583b3d8 "add a vfs_fsync helper" doesn't work for nfsd. Revert the parts of those patches that touch nfsd. Note: we can't, however, remove the logic from vfs_fsync that was needed only for the special case of nfsd, because a vfs_fsync(NULL,...) call can still result indirectly from a stackable filesystem that was called by nfsd.

2009-01-07svc: Move kfree of deferral record to common codeTom Tucker
The rqstp structure has a pointer to a svc_deferred_req record that is allocated when requests are deferred. This record is common to all transports and can be freed in common code. Move the kfree of the rq_deferred to the common svc_xprt_release function.

2009-01-07CRED: Fix NFSD regressionDavid Howells
Fix a regression in NFSD's permission checking introduced by the credentials patches. There are two parts to the problem, both in nfsd_setuser(): (1) The return value of set_groups() is -ve if in error, not 0, and should be checked appropriately. 0 indicates success. (2) The UID to use for fs accesses is in new->fsuid, not new->uid (which is 0). This causes CAP_DAC_OVERRIDE to always be set, rather than being cleared if the UID is anything other than 0 after squashing. Reported-by: J.

2009-01-07nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKTJ. Bruce Fields
Since nfsv4 allows LOCKT without an open, but the ->lock() method is a file method, we fake up a struct file in the nfsv4 code with just the fields we need initialized. But we forgot to initialize the file operations, with the result that LOCKT never results in a call to the filesystem's ->lock() method (if it exists). We could just add that one more initialization. But this hack of faking up a struct file with only some fields initialized seems the kind of thing that might cause more problems in the future. We should either do an open and get a real struct file, or make lock-testing an inode (not a file) method. This patch does the former.

2009-01-07stop_machine/cpu hotplug: fix disable_nonboot_cpusHeiko Carstens
disable_nonboot_cpus calls _cpu_down. But _cpu_down requires that the caller already created the stop_machine workqueue (like cpu_down does). Otherwise a call to stop_machine will lead to accesses to random memory regions. When introducing this new interface (9ea09af3bd3090e8349ca2899ca2011bd94cda85 "stop_machine: introduce stop_machine_create/destroy") I missed the second call site of _cpu_down. So add the missing stop_machine_create/destroy calls to disable_nonboot_cpus as well. Fixes suspend-to-ram/disk and also this bug: [ 286.547348] BUG: unable to handle kernel paging request at 6b6b6b6b [ 286.548940] IP: [<c0150ca4>] __stop_machine+0x88/0xe3 [ 286.550598] Oops: 0002 [#1] SMP [ 286.560580] Pid: 3273, comm: halt Not tainted (2.6.28-06127-g238c6d5 [ 286.560580] EIP: is at __stop_machine+0x88/0xe3 [ 286.560580] Process halt (pid: 3273, ti=f1a28000 task=f4530f30 [ 286.560580] Call Trace: [ 286.560580] [<c03d04e4>] ? _cpu_down+0x10f/0x234 [ 286.560580] [<c012a57e>] ? disable_nonboot_cpus+0x58/0xdc [ 286.560580] [<c01360c0>] ? kernel_poweroff+0x22/0x39 [ 286.560580] [<c0136301>] ? sys_reboot+0xde/0x14c [ 286.560580] [<c01331b2>] ? complete_signal+0x179/0x191 [ 286.560580] [<c0133396>] ? send_signal+0x1cc/0x1e1 [ 286.560580] [<c03de418>] ? _spin_unlock_irqrestore+0x2d/0x3c [ 286.560580] [<c0133b65>] ? group_send_signal_info+0x58/0x61 [ 286.560580] [<c0133b9e>] ? kill_pid_info+0x30/0x3a [ 286.560580] [<c0133d49>] ? sys_kill+0x75/0x13a [ 286.560580] [<c01a06cb>] ? mntput_no_expire+ox1f/0x101 [ 286.560580] [<c019b3b3>] ? dput+0x1e/0x105 [ 286.560580] [<c018ef87>] ? __fput+0x150/0x158 [ 286.560580] [<c0157abf>] ? audit_syscall_entry+0x137/0x159 [ 286.560580] [<c010329f>] ? sysenter_do_call+0x12/0x34 Reported-and-tested-by: "Justin P.

2009-01-07HID: fix hid->hiddev initialization in hiddev_connect()Jiri Kosina
Commit 079034073fa ("HID: hiddev cleanup -- handle all error conditions properly") by mistake removed proper initialization of hid->hiddev pointer in hiddev_connect() in case usb_register_dev() succeeds for the hiddev node. Put it properly back in place. Reported-and-tested-by: Gabriel C <nix.or.die@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
