2009-01-28x86, apic: remove IRQ_DEST_MODE / IRQ_DELIVERY_MODEIngo Molnar
Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE. The typical 32-bit and the 64-bit build all dereference via the genapic, so it's pointless to hide that indirection via these ugly macros. Furthermore, it also obscures subarchitecture details. So replace it with apic->irq_dest_mode / etc. accesses. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, genapic: rename int_delivery_mode, et. al.Ingo Molnar
int_delivery_mode is supposed to mean 'interrupt delivery mode', but it's quite a misnomer as 'int' we usually think of as an integer type ... The standard naming for such attributes is 'irq' - so rename the following fields and macros: int_delivery_mode => irq_delivery_mode INT_DELIVERY_MODE => IRQ_DELIVERY_MODE int_dest_mode => irq_dest_mode INT_DEST_MODE => IRQ_DEST_MODE Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up apic->apic_id_registered() methodsIngo Molnar
Impact: cleanup x86 subarchitectures each defined a "apic_id_registered()" method, which could be an inline function depending on which subarch we build for, and which was also the name of a genapic field. Untangle this namespace spaghetti by giving each of the instances a separate name. Also remove wrapper macro obfuscation. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up apic->acpi_madt_oem_check methodsIngo Molnar
Impact: refactor code x86 subarchitectures each defined a "acpi_madt_oem_check()" method, which could be an inline function, or an extern, or a static function, and which was also the name of a genapic field. Untangle this namespace spaghetti by setting ->acpi_madt_oem_check() to NULL on those subarchitectures that have no detection quirks, and rename the other ones (summit, es7000) that do. Also change default_acpi_madt_oem_check() to handle NULL entries, and clean its control flow up as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: remove APIC_INIT / APICFUNC / IPIFUNCIngo Molnar
The APIC_INIT() / APICFUNC / IPIFUNC macros were ugly and obfuscated the true identity of various APIC driver methods. Now that they are not used anymore, remove them. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, genapic: cleanup 32-bit apic_summit templateIngo Molnar
Clean up the APIC driver template: - order fields properly - use the macro names explicitly (so that they can be renamed later) - fill in NULL entries as well Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-28x86: rename 'genapic' to 'apic'Ingo Molnar
Rename genapic-> to apic-> references because in a future chagne we'll open-code all the indirect calls (instead of obscuring them via macros), so we want this reference to be as short as possible. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, genapic: provide IPI callbacks unconditionallyIngo Molnar
64-bit x86 uses the IPI callbacks even on UP - so provide them generally. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-26x86: correct the CPUID pattern for MSR_IA32_MISC_ENABLE availabilityH. Peter Anvin
Impact: re-enable CPUID unmasking on affected processors As far as I am capable of discerning from the documentation, MSR_IA32_MISC_ENABLE should be available for all family 0xf CPUs, as well as family 6 for model >= 0xd (newer Pentium M). The documentation on this isn't ideal, so we need to be on the lookout for errors, still. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
