2009-01-28x86, apic: clean up check_apicid*() callbacksIngo Molnar
Clean up these methods - to make it clearer which function is used in which case. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: rename genapic::apic_destination_logical to genapic::dest_logicalIngo Molnar
This field name was unreasonably long - shorten it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up the APIC_DEST_LOGICAL logicIngo Molnar
Impact: cleanup The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in a rather nasty way by re-defining it to zero. That is infinitely fragile and makes it very hard to see what to code really does in a given context. The very same constant has different meanings and values - depending on which subarch is enabled. Untangle this mess by never undefining the constant, but instead propagating the right values into the genapic driver templates. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: rename ->ESR_DISABLE to ->disable_esrIngo Molnar
the ->ESR_DISABLE shouting variant was used to enable the esr_disable macro wrappers. Those ugly macros are removed now so we can rename ->ESR_DISABLE to ->disable_esr Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: clean up esr_disable() methodsIngo Molnar
Impact: cleanup Most subarchitectures want to disable the APIC ESR (Error Status Register), because they generally have hardware hacks that wrap standard CPUs into a bigger system and hence the APIC bus is quite non-standard and weirdnesses (lockups) have been seen with ESR reporting. Remove the esr_disable macros and put the desired flag into each subarchitecture's genapic template directly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up / remove TARGET_CPUSIngo Molnar
Impact: cleanup use apic->target_cpus() directly instead of the TARGET_CPUS wrapper. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up target_cpus methodsIngo Molnar
Impact: cleanup Clean up all the target_cpus() namespace overlap that exists between bigsmp, es7000, mach-default, numaq and summit - by separating the different functions into different names. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove IRQ_DEST_MODEIngo Molnar
Remove leftover definition. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove ES7000_IRQ_DELIVERY_MODE and ES7000_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_es7000 driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove BIGSMP_IRQ_DELIVERY_MODE and BIGSMP_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_bigsmp driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove NUMAQ_IRQ_DELIVERY_MODE and NUMAQ_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_numaq template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove SUMMIT_IRQ_DELIVERY_MODE and SUMMIT_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_summit template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: remove DEFAULT_IRQ_DELIVERY_MODE and DEFAULT_IRQ_DEST_MODEIngo Molnar
Impact: cleanup They were only used in a single place and obscured the apic_default template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
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: clean up apic_x2apic_clusterIngo Molnar

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>

2009-01-28x86, genapic: refactor genapic_32.hIngo Molnar
Impact: pre unification cleanup Make genapic_32.h similar to genapic_64.h: reorder fields, unify types and bring in new entries. No existing functionality is affected. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-28powerpc/mm: Fix handling of _PAGE_COHERENT in BAT setup codeGerhard Pircher
_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set. This will work on normal SMP setups because we force-set CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

2009-01-28powerpc/pseries: Correct VIO bus accounting problem in CMO env.Robert Jennings
In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path.
