2013-05-01drm: proc: Use remove_proc_subtree()David Howells
Use remove_proc_subtree() rather than remove_proc_entry() to remove a minor-specific drm proc directory and all its children. Things could theoretically be improved by storing the drm_minor pointer in the minor-specific dir proc_dir_entry struct data and then scrapping the list of proc files - but that's shared with the debugfs interface where you can't do that, so I don't see an easy way of doing it.

2013-05-01drm: proc: Use minor->index to label things, not PDE->nameDavid Howells
Use minor->index to label things, not the name field from the proc_dir_entry of the /proc/dwm/<minor>/ directory. Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which to render the integer, not a 16-byte buffer. The longest string an unsigned int can give you is 10 chars (4294967295) plus a NUL, so round up to 12 as the stack is likely to be 4- or 8-byte aligned.

2013-05-01proc: Supply an accessor for getting the data from a PDE's parentDavid Howells
Supply an accessor function for getting the private data from the parent proc_dir_entry struct of the proc_dir_entry struct associated with an inode. ReiserFS, for instance, stores the super_block pointer in the proc directory it makes for that super_block, and a pointer to the respective seq_file show function in each of the proc files in that directory. This allows a reduction in the number of file_operations structs, open functions and seq_operations structs required. The problem otherwise is that each show function requires two pieces of data but only has storage for one per PDE (and this has no release function).

2013-05-01tty: fix up atime/mtime mess, take threeLinus Torvalds
We first tried to avoid updating atime/mtime entirely (commit b0de59b5733d: "TTY: do not update atime/mtime on read/write"), and then limited it to only update it occasionally (commit 37b7f3c76595: "TTY: fix atime/mtime regression"), but it turns out that this was both insufficient and overkill. It was insufficient because we let people attach to the shared ptmx node to see activity without even reading atime/mtime, and it was overkill because the "only once a minute" means that you can't really tell an idle person from an active one with 'w'. So this tries to fix the problem properly. It marks the shared ptmx node as un-notifiable, and it lowers the "only once a minute" to a few seconds instead - still long enough that you can't time individual keystrokes, but short enough that you can tell whether somebody is active or not.

2013-05-01dma-buf: replace dma_buf_export() with dma_buf_export_named()Sumit Semwal
For debugging purposes, it is useful to have a name-string added while exporting buffers. Hence, dma_buf_export() is replaced with dma_buf_export_named(), which additionally takes 'exp_name' as a parameter. For backward compatibility, and for lazy exporters who don't wish to name themselves, a #define dma_buf_export() is also made available, which adds a __FILE__ instead of 'exp_name'.

Move the calls to memcpy_fromio() up into the loop in dmi_scan_machine(), and move the signature checks back down into dmi_decode(). We need to check at 16-byte intervals but keep a 32-byte buffer for an SMBIOS entry, so shift the buffer after each iteration. Merge smbios_present() into dmi_present(), so we look for an SMBIOS signature at the beginning of the given buffer and then for a DMI signature at an offset of 16 bytes.

2013-04-30dump_stack: implement arch-specific hardware description in task dumpsTejun Heo
x86 and ia64 can acquire extra hardware identification information from DMI and print it along with task dumps; however, the usage isn't consistent. * x86 show_regs() collects vendor, product and board strings and print them out with PID, comm and utsname. Some of the information is printed again later in the same dump. * warn_slowpath_common() explicitly accesses the DMI board and prints it out with "Hardware name:" label. This applies to both x86 and ia64 but is irrelevant on all other archs. * ia64 doesn't show DMI information on other non-WARN dumps. This patch introduces arch-specific hardware description used by dump_stack(). It can be set by calling dump_stack_set_arch_desc() during boot and, if exists, printed out in a separate line with "Hardware name:" label. dmi_set_dump_stack_arch_desc() is added which sets arch-specific description from DMI data. It uses dmi_ids_string[] which is set from dmi_present() used for DMI debug message. It is superset of the information x86 show_regs() is using. The function is called from x86 and ia64 boot code right after dmi_scan_machine(). This makes the explicit DMI handling in warn_slowpath_common() unnecessary. Removed. show_regs() isn't yet converted to use generic debug information printing and this patch doesn't remove the duplicate DMI handling in x86 show_regs(). The next patch will unify show_regs() handling and remove the duplication. An example WARN dump follows.

We're goning to use DMI identification for other purposes too. Morph dmi_dump_ids() which is used to print DMI identification as a debug message during boot into dmi_format_ids() which formats the same information sans the leading "DMI:" tag into a string buffer. dmi_present() is updated to format the information into dmi_ids_string[] using the new function and print it with "DMI:" prefix. dmi_ids_string[] will be used for another purpose by a future patch.
