| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add CONFIG_OPTIMIZE_INLINING=y. allow gcc to optimize the kernel image's size by uninlining functions that have been marked 'inline'. Previously gcc was forced by Linux to always-inline these functions via a gcc attribute: #define inline inline __attribute__((always_inline)) Especially when the user has already selected CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in kernel image size (using a standard Fedora .config): text data bss dec hex filename 5613924 562708 3854336 10030968 990f78 vmlinux.before 5486689 562708 3854336 9903733 971e75 vmlinux.after that's a 2.3% text size reduction (!).

There is no change in what it does. I also separated the recently-added DF bit clearing from the TF diddling. The compiler turns them back into one instruction anyway.

| * | x86: remove NexGen supportDmitri Vorobiev2008-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is claimed that NexGen CPUs were never shipped: http://lkml.org/lkml/2008/4/20/179 Also, the kernel support for these chips has been broken for a long time, the code intended to support NexGen thereby being essentially dead. As an outcome of the discussion that can be found using the URL above, this patch removes the NexGen support altogether. The changes in this patch survived a defconfig build for i386, a couple of successful randconfig builds, as well as a runtime test, which consisted in booting a 32-bit x86 box up to the shell prompt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In arch/x86/kernel/setup_64.c, the standard_io_resources array is needlessly defined as global. This patch makes this variable static. This patch was successfully build-tested using the defconfig for x86_64. Runtime test was performed by booting a 64-bit x86 box up to the shell prompt.

This patch was build-tested using defconfigs for i386 and x86_64, and a few randconfig instances. Runtime tests were performed by booting 32- and 64-bit x86 boxen up to the shell prompt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least on my Barcelona, I see MCE log entries after cold boot caused by BIOS not properly clearing the respective registers. Therefore, this patch extends the workaround to families 0x10 and 0x11 (the latter just for completeness, I have nothing to verify this against). At the same time, provide a way to make these entries visible via the 'mce=bootlog' command line option even on these machines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There apparently was an unnoticed conflict between an earlier patch to this file and mine (d1e084746b0e5806e6345ab31c5b370f8dee2b23), which I noticed only now. I suppose a change like the one below (untested) is needed; I didn't get any response on a confirmation request for this from the submitter of the first patch. The issue is the writing of the 'checkbit' member at the end of setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops rather than wd_ops.

| * [POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseriesMichael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [POWERPC] Convert from DBG() to pr_debug() in platforms/pseries/Michael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In pseries/lpar.c, fix some printf specifier mismatches, and add a newline to one printk. In pseries/rtasd.c add "rtasd" to some messages to make it clear where they're coming from. In pseries/scanlog.c remove the hand-rolled runtime debugging support in there. This file has been largely unchanged for eons, if we need to debug it in future we can recompile.

| * [POWERPC] Register udbg console early on pseries LPARMichael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps.
