* x86: reduce CONFIG_X86_PPRO_FENCE bloatNick Piggin2008-01-301-1/+10
| | | | | | | | | | | | | | | | | | | | | CONFIG_X86_PPRO_FENCE bloats text: i386 allmodconf: size mm/built-in.o text data bss dec hex text ratio vanilla: 163082 20372 40120 223574 36956 100.00% bugfix : 163509 20372 40120 224001 36b01 0.26% noppro : 162191 20372 40120 222683 365db - 0.55% both : 162267 20372 40120 222759 36627 - 0.50% (+0.05% vs noppro) So with the ppro memory ordering bug out of the way, the PG_uptodate fix only adds 76 bytes of text. allow this config to be specified by distros.

* x86: debugctlmsr kconfigRoland McGrath2008-01-301-0/+4
| | | | | | | | | | | | | | This adds the (internal) Kconfig macro CONFIG_X86_DEBUGCTLMSR, to be defined when configuring to support only hardware that definitely supports MSR_IA32_DEBUGCTLMSR with the BTF flag. The Intel documentation says "P6 family" and later processors all have it. I think the Kconfig dependencies are right to have it set for those and unset for others (i.e., when 586 and earlier are supported).

* x86: move i386 and x86_64 Kconfig files to x86 directorySam Ravnborg2007-10-251-0/+372
After a small change in kconfig Makefile we could move all x86 Kconfig files to x86 directory. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
