The tools/perf/util/rbtree.c copy already drifted by three csets: 4b324126 4c601178 16c047ad So remove the copy and use the lib/rbtree.c directly, sharing the source code while still generating a separate object file, since tools/perf uses a far more agressive -O6 switch. Signed-off-by:

Paul Mackerras authored
This reworks the parser for event descriptors to make it more consistent in what it accepts. It is now structured as a recursive descent parser for the following grammar: events ::= event ( ("," | space) space* event )* event ::= ( raw_event | numeric_event | symbolic_event | generic_hw_event ) [ event_modifier ] raw_event ::= "r" hex_number numeric_event ::= number ":" number number ::= decimal_number | "0x" hex_number | "0" octal_number symbolic_event ::= string_from_event_symbols_array generic_hw_event::= cache_type ( "-" ( cache_op | cache_result ) )* event_modifier ::= ":" ( "u" | "k" | "h" )+ with the extra restriction that you can have at most one cache_op and at most one cache_result. We pass the current string pointer by reference (i.e. as a const char **) to the various parsing functions so that they can advance the pointer to indicate how much they consumed. They return 0 if they didn't recognize the thing at the pointer or 1 if they did (and advance the pointer past it). This also fixes parse_aliases to take the longest matching alias from the table, not the first one. Otherwise "l1-data" would match the "l1-d" alias and the "ata" would not be consumed. This allows event modifiers indicating what processor modes to count in to be applied to any event, not just numeric events, and adds a ":h" modifier to indicate counting in hypervisor mode. Specifying ":u" now sets both exclude_kernel and exclude_hv, and so on. Multiple modes can be specified, e.g. ":uk" will count in user or hypervisor mode (i.e. only exclude_kernel will be set).

The symbol resolving has of course revealed some bugs in the callchain tree handling. This patch fixes some of them, including: - inherit the children from the parents while splitting a node - fix list range moving - fix indexes setting in callchains - create a child on the current node if the path doesn't match in the existent children (was only done on the root) - compare using symbols when possible so that we can match a function using any ip inside by referring to its start address. The practical effects are: - remove double callchains - fix upside down or any random order of callchains - fix wrong paths - fix bad hits and percentage accounts Signed-off-by:

balance_dirty_pages can overreact and move all of the dirty pages to writeback unnecessarily. balance_dirty_pages makes its decision to throttle based on the number of dirty plus writeback pages that are over the calculated limit,so it will continue to move pages even when there are plenty of pages in writeback and less than the threshold still dirty. This allows it to overshoot its limits and move all the dirty pages to writeback while waiting for the drives to catch up and empty the writeback list. A simple fio test easily demonstrates this problem. fio --name=f1 --directory=/disk1 --size=2G -rw=write --name=f2 --directory=/disk2 --size=1G --rw=write --startdelay=10 This is the simplest fix I could find, but I'm not entirely sure that it alone will be enough for all cases. But it certainly is an improvement on my desktop machine writing to 2 disks. Do we need something more for machines with large arrays where bdi_threshold * number_of_drives is greater than the dirty_ratio ? Signed-off-by:

Bugfix to spi_bitbang infrastructure: make sure to always set transfer parameters on the first pass through the message's per-transfer loop. This can matter with drivers that replace the per-word or per-buffer transfer primitives, on busses with multiple SPI devices. Previously, this could have started messages using the settings left after previous messages. The problem was observed when a high speed chip (m25p80 type flash) was running very slowly because a low speed device (avr8 microcontroller) had previously used the bus. Similar faults could have driven the low speed device too fast, or used an unexpected word size. Acked-by:

Add a mutex to avoid a circular locking problem between the mm layer semaphore and fbdev ioctl mutex through the fb_mmap() call. Also, add mutex to all places where smem_start and smem_len fields change so the mutex inside the fb_mmap() is actually used. Changing of these fields before calling the framebuffer_register() are not mutexed. This is 2.6.31 material. It removes one lockdep (fb_mmap() and register_framebuffer()) but there is still another one (fb_release() and register_framebuffer()). It also cleans up handling of the smem_start and smem_len fields used by mutexed section of the fb_mmap(). Signed-off-by:

Add a new spi_master.flags word listing constraints relevant to that controller. Define the first constraint bit: a half duplex restriction. Include that constraint in the OMAP1 MicroWire controller driver. Have the mmc_spi host be the first customer of this flag. Its coding relies heavily on full duplex transfers, so it must fail when the underlying controller driver won't perform them. (The spi_write_then_read routine could use it too: use the temporarily-withdrawn full-duplex speedup unless this flag is set, in which case the existing code applies. Similarly, any spi_master implementing only SPI_3WIRE should set the flag.) Signed-off-by:

Add two new spi_device.mode bits to accomodate more protocol options, and pass them through to usermode drivers: * SPI_NO_CS ... a second 3-wire variant, where the chipselect line is removed instead of a data line; transfers are still full duplex. This obviously has STRONG protocol implications since the chipselect transitions can't be used to synchronize state transitions with the SPI master. * SPI_READY ... defines open drain signal that's pulled low to pause the clock. This defines a 5-wire variant (normal 4-wire SPI plus READY) and two 4-wire variants (READY plus each of the 3-wire flavors). Such hardware flow control can be a big win. There are ADC converters and flash chips that expose READY signals, but not many host controllers support it today. The spi_bitbang code should be changed to use SPI_NO_CS instead of its current nonportable hack. That's a mode most hardware can easily support (unlike SPI_READY). Signed-off-by:

ext2_iget() returns -ESTALE if invoked on a deleted inode, in order to report errors to NFS properly. However, in ext[234]_lookup(), this -ESTALE can be propagated to userspace if the filesystem is corrupted such that a directory entry references a deleted inode. This leads to a misleading error message - "Stale NFS file handle" - and confusion on the part of the admin. The bug can be easily reproduced by creating a new filesystem, making a link to an unused inode using debugfs, then mounting and attempting to ls -l said link. This patch thus changes ext2_lookup to return -EIO if it receives -ESTALE from ext2_iget(), as ext2 does for other filesystem metadata corruption; and also invokes the appropriate ext*_error functions when this case is detected.

With ELF, at generating coredump, some more headers other than used vmas are added. When max_map_count == 65536, a core generated by following kinds of code can be unreadable because the number of ELF's program header is written in 16bit in Ehdr (please see elf.h) and the number overflows. == ... = mmap(); (munmap, mprotect, etc...) if (failed) abort(); == This can happen in mmap/munmap/mprotect/etc...which calls split_vma(). I think 65536 is not safe as _default_ and reduce it to 65530 is good for avoiding unexpected corrupted core. Anyway, max_map_count can be enlarged by sysctl if a user is brave.. Signed-off-by:
