2006-12-07[PATCH] paravirt: Patch inline replacements for paravirt interceptsRusty Russell1-0/+2
It turns out that the most called ops, by several orders of magnitude, are the interrupt manipulation ops. These are obvious candidates for patching, so mark them up and create infrastructure for it. The method used is that the ops structure has a patch function, which is called for each place which needs to be patched: this returns a number of instructions (the rest are NOP-padded). Usually we can spare a register (%eax) for the binary patched code to use, but in a couple of critical places in entry.S we can't: we make the clobbers explicit at the call site, and manually clobber the allowed registers in debug mode as an extra check. And: Don't abuse CONFIG_DEBUG_KERNEL, add CONFIG_DEBUG_PARAVIRT.

2006-11-25[PATCH] initramfs: handle more than one source dir or file listThomas Chou1-1/+2
Fix bug 7401. Handle more than one source dir or file list to the initramfs gen scripts. The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple space-separated sources in order to allow unprivileged users to build an image. There are two bugs in the current implementation that prevent this from working. First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it obviously can't open. Second, gen_initramfs_list.sh -l outputs multiple definitions for deps_initramfs -- one for each argument.

2006-10-01[PATCH] allow /proc/config.gz to be built as a moduleRoss Biro1-1/+1
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.

2006-09-30kconfig/lxdialog: let <ESC><ESC> behave as expectedSam Ravnborg8-30/+76
<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.

2006-09-27[PATCH] EISA bus MODALIAS attributes supportMichael Tokarev1-0/+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>
2006-09-26[PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinderJan Beulich1-2/+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>

2006-09-25kbuild: fix "mkdir -p" usage in scripts/package/mkspecRolf Eike Beer1-2/+2
"mkdir -p" does not only mean not to complain if the directory already exists, but also to create the parent directories if needed. This patch removes "lib" from the list of directories to create as we will also create "lib/modules".

2006-09-25kbuild: fail kernel compilation in case of unresolved module symbolsKirill Korotaev2-6/+20
At stage 2 modpost utility is used to check modules. In case of unresolved symbols modpost only prints warning. IMHO it is a good idea to fail compilation process in case of unresolved symbols (at least in modules coming with kernel), since usually such errors are left unnoticed, but kernel modules are broken. - new option '-w' is added to modpost: if option is specified, modpost only warns about unresolved symbols - modpost is called with '-w' for external modules in Makefile.modpost Signed-off-by: Andrey Mirkin <amirkin@sw.ru> Signed-off-by: Kirill Korotaev <dev@openvz.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-09-25kbuild: create output directory for hostprogs with O=.. buildSam Ravnborg1-5/+16
hostprogs-y only supported creating output directory for the final program. Extend this to also cover the situation where a .o file (used when host program is made from compositie objects) is locate in another directory. First user of this is the built-in lxdialog that.

2006-09-25kbuild: make V=2 tell why a target is rebuildSam Ravnborg1-1/+40
tell why a a target got build enabled by make V=2 Output (listed in the order they are checked): (1) - due to target is PHONY (2) - due to target missing (3) - due to: file1.h file2.h (4) - due to command line change (5) - due to missing .cmd file (6) - due to target not in $(targets) (1) We always build PHONY targets (2) No target, so we better build it (3) Prerequisite is newer than target (4) The command line stored in the file named dir/.target.cmd differed from actual command line. This happens when compiler options changes (5) No dir/.target.cmd file (used to store command line) (6) No dir/.target.cmd file and target not listed in $(targets) This is a good hint that there is a bug in the kbuild file This patch is inspired by a patch from: Milton Miller <miltonm@bga.com> Cc: Milton Miller <miltonm@bga.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-25kbuild: modpost on vmlinux regardless of CONFIG_MODULESSam Ravnborg2-4/+10
Based on patch from: Magnus Damm <magnus@valinux.co.jp> This has the advantage that all section mismatch checks are run regardless of modules being enabled or not. When running modpost on vmlinux output: MODPOST vmlinux When running modpost on modules output count of modules like this: MODPOST 5 modules Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
