* [POWERPC] Support feature fixups in modulesBenjamin Herrenschmidt2006-10-251-0/+2
| | | | | | | | | | | This patch adds support for feature fixups in modules. This involves adding support for R_PPC64_REL64 relocs to the 64 bits module loader. It also modifies modpost.c to ignore the powerpc fixup sections (or it would warn when used in .init.text).

* [PATCH] kbuild: allow multi-word $M in Makefile.modpostGreg Banks2006-10-171-1/+1
| | | | | | | | | | | | Some people want to do crazy things like pass multiple directories as the value of $(SUBDIRS) or $M. Mostly this kinda works, except that Makefile.modpost constructs a modpost commandline which fails modpost's argument parsing. This patch fixes that little wrinkle.

* [PATCH] kernel-doc: make parameter description indentation uniformRandy Dunlap2006-10-111-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | - In parameter descriptions, strip all whitespace between the parameter name (e.g., @len) and its description so that the description is indented uniformly in text and man page modes. Previously, spaces or tabs (which are used for cleaner source code viewing) affected the produced output in a negative way. Before (man mode): to Destination address, in user space. from Source address, in kernel space. n Number of bytes to copy. After (man mode): to Destination address, in user space. from Source address, in kernel space. n Number of bytes to copy. - Fix/clarify a few function description comments.

KBUILD_MODPOST_WARN can be set to make modpost warn instead of error out in case on unresolved symbols in final module link.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | <ESC><ESC> is used to step one back in the dialogs. When lxdialog became built-in pressing <ESC> once would cause one step back and pressing <ESC><ESC> would cause two steps back. This patch - based on concept from Roman Zippel <zippel@linux-m68k.org> - makes one <ESC> a noop and pressing <ESC><ESC> will cause one step backward. In addition the final yes/no dialog now has the option to go back to the the kernel configuration. So if you get too far out you can now go back to configuring the kernel without saving and starting all over again. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * kconfig/lxdialog: add a new theme bluetitle which is now defaultSam Ravnborg2006-09-302-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bluetitle theme is a slightly modified version of the colorscheme that -mm users has been used to. The bluetitle is more readable especially on some LCD screens so it is now default. Anyone that really wants the old color selection can get it by selecting the classic color theme: make MENUCONFIG_COLOR=classic menuconfig The bluetitle theme was modified by Roman Zippel <zippel@linux-m68k.org> to further improve readability on LCD screens.

|/ | | | | | | | | | | | | | | | | | The driver for /proc/config.gz consumes rather a lot of memory and it is in fact possible to build it as a module. In some ways this is a bit risky, because the .config which is used for compiling kernel/configs.c isn't necessarily the same as the .config which was used to build vmlinux. But OTOH the potential memory savings are decent, and it'd be fairly dumb to build your configs.o with a different .config.

* [PATCH] EISA bus MODALIAS attributes supportMichael Tokarev2006-09-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by: Jeff Garzik <jeff@garzik.org> Acked-the-tulip-bit-by: Valerie Henson <val_henson@linux.intel.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinderJan Beulich2006-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Current gcc generates calls not jumps to noreturn functions. When that happens the return address can point to the next function, which confuses the unwinder. This patch works around it by marking asynchronous exception frames in contrast normal call frames in the unwind information. Then teach the unwinder to decode this. For normal call frames the unwinder now subtracts one from the address which avoids this problem. The standard libgcc unwinder uses the same trick. It doesn't include adjustment of the printed address (i.e. for the original example, it'd still be kernel_math_error+0 that gets displayed, but the unwinder wouldn't get confused anymore. This only works with binutils 2.6.17+ and some versions of H.J.Lu's 2.6.16 unfortunately because earlier binutils don't support .cfi_signal_frame [AK: added automatic detection of the new binutils and wrote description] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de>

* | kconfig: support DOS line endingsMatthew Wilcox2006-09-251-2/+6
|/ | | | | | | | | | Kconfig doesn't currently handle config files with DOS line endings. While these are, of course, an abomination, etc, etc, it can be handy to not have to convert them first. It's also a tiny patch and even adds support for lines ending in just \r or even \n\r. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * [S390] zcrypt adjunct processor bus.Martin Schwidefsky2006-09-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a bus for the adjunct processor interface. Up to 64 devices can be connect to the ap bus interface, each device with 16 domains. That makes 1024 message queues. The interface is asynchronous, the answer to a message sent to a queue needs to be received at some later point in time. Unfortunately the interface does not provide interrupts when a message reply is pending. So the ap bus needs to implement some fancy polling, each active queue is polled once per 1/HZ second or continuously if an idle cpus exsists and the poll thread is activ (see poll_thread parameter). The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes, ap_domain and config_time. The ap_domain selects one of the 16 domains to be used for this system. This limits the maximum number of ap devices to 64. The config_time attribute contains the number of seconds between two ap bus scans to find new devices. The ap bus uses the modalias entries of the form "ap:tN" to autoload the ap driver for hardware type N. Currently known types are: 3 - PCICC, 4 - PCICA, 5 - PCIXCC, 6 - CEX2A and 7 - CEX2C.
