2006-06-25[PATCH] kernel-doc: use Members for struct fields consistentlyRandy Dunlap1-1/+1
kernel-doc struct fields should be consistently called "Members", not "Arguments", so switch man-mode output to use "Members" like all of the other formats do.

2006-06-25[PATCH] kernel-doc: warn on malformed function docs.Randy Dunlap1-0/+7
When the verbose (-v) option is used with scripts/kernel-doc, this option reports when the kernel-doc format is malformed and apparently contains function description lines before function parameters. In these cases, the kernel-doc script will print something like: Warning(filemap.c:335): contents before sections I have fixed the problems in mm/filemap.c and added lots of kernel-doc to that file (posted to the linux-mm mailing list Mon. 2006-June-12). The real goal (as requested by Andrew Morton) is to allow the short function description to be more than one line long. This patch is both a kernel-doc checker and a tool en route to that goal.

2006-06-25[PATCH] checkstack: print module namesRandy Dunlap1-2/+12
Finding "init_module" high stack usage problems is challenging when there are over 1600 "init_module" functions in the kernel tree, so make checkstack.pl print out the filename where the stack usage occurs. This is useful for code built as loadable modules. For built-in code, it just prints the kernel image file name, like "vmlinux". Examples: (before patch:) 0x0000000d callback: 1928 0xffffffff81678c09 huft_build: 1560 0x0018 init_module: 1512 (after patch:) 0x0000000d callback [divacapi]: 1928 0xffffffff81678c09 huft_build [vmlinux]: 1560 0x0018 init_module [hdaps]: 1512 Also change one if-series to use elsif to cut down on unneeded tests.

2006-06-25[PATCH] kernel-doc: drop leading space in sectionsRandy Dunlap1-0/+3
Drop leading space of kernel-doc section contents. "Section" data (contents) are split from the section header (e.g., Note: below is a section header: * Note: list_empty on entry does not return true after this, the entry is * in an undefined state. ). Currently the data/contents begins with a space and is left that way, which causes it to look bad when printed (in text mode; see example below), so just remove the leading space. Note: list_empty on entry does not return true after this, the entry is in an undefined state.

2006-05-21[PATCH] kbuild: check SHT_REL sectionsAtsushi Nemoto2-19/+48
I found that modpost can not detect section mismatch on mips and i386. On mips64, the modpost (with r_info layout fix) can detect it. The current modpst only checks SHT_RELA section but I suppose SHT_REL section should be checked also. This patch does not contain r_info layout fix. I'll post an updated r_info layout fix on next mail. Check SHT_REL sections as like as SHT_RELA sections to detect section mismatch.

Randy.Dunlap <rdunlap@xenotime.net> pointed out a similar set of warnings for a number of scsi drivers.

Randy.Dunlap <rdunlap@xenotime.net> also pointed out a scsi driver with many references to .exit.text from .rodata.

2006-04-11kbuild: rebuild initramfs if content of initramfs changesSam Ravnborg1-73/+152
initramfs.cpio.gz being build in usr/ and included in the kernel was not rebuild when the included files changed. To fix this the following was done: - let gen_initramfs.sh generate a list of files and directories included in the initramfs - gen_initramfs generate the gzipped cpio archive so we could simplify the kbuild file (Makefile) - utilising the kbuild infrastructure so when uid/gid root mapping changes the initramfs will be rebuild With this change we have a much more robust initramfs generation.

2006-03-25[PATCH] x86_64: Basic reorder infrastructureArjan van de Ven1-0/+21
This patch puts the infrastructure in place to allow for a reordering of functions based inside the vmlinux. The general idea is that it is possible to put all "common" functions into the first 2Mb of the code, so that they are covered by one TLB entry. This as opposed to the current situation where a typical vmlinux covers about 3.5Mb (on x86-64) and thus 2 TLB entries. This is done by enabling the -ffunction-sections flag in gcc, which puts each function in its own ELF section, so that the linker can then order them in a way defined by the linker script. As per previous discussions, Linus said he wanted a "static" list for this, eg a list provided by the kernel tarbal, so that most people have the same ordering at least. A script is provided to create this list based on readprofile(1) output. The included list is provisional, and entirely biased on my own testbox and me running a few kernel compiles and some other things. I think that to get to a better list we need to invite people to submit their own profiles, and somehow add those all up and base the final list on that. I'm willing to do that effort if this is ends up being the prefered approach. Such an effort probably needs to be repeated like once a year or so to adopt to the changing nature of the kernel. Made it a CONFIG with default n because it increases link times dramatically. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
