* x86, apic: clean up ->init_apic_ldr()Ingo Molnar2009-01-28
| | | | | | | | - separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->vector_allocation_domain()Ingo Molnar2009-01-28
| | | | | | | | | | | | - separate the namespace - remove macros - move the default vector-allocation-domain to mach-generic - fix whitespace damage Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove no_balance_irq and no_ioapic_check flagsIngo Molnar2009-01-28
| | | | | | | These flags are completely unused. (the in-kernel IRQ balancer has been removed from the upstream kernel.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up check_apicid*() callbacksIngo Molnar2009-01-28
| | | | | | | Clean up these methods - to make it clearer which function is used in which case. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: rename genapic::apic_destination_logical to genapic::dest_logicalIngo Molnar2009-01-28
| | | | | | This field name was unreasonably long - shorten it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up the APIC_DEST_LOGICAL logicIngo Molnar2009-01-28
| | | | | | | | | | | | | | | 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>
* x86: rename ->ESR_DISABLE to ->disable_esrIngo Molnar2009-01-28
| | | | | | | | 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>
* x86: clean up esr_disable() methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | 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>
* x86, apic: clean up / remove TARGET_CPUSIngo Molnar2009-01-28
| | | | | | | | Impact: cleanup use apic->target_cpus() directly instead of the TARGET_CPUS wrapper. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up target_cpus methodsIngo Molnar2009-01-28
| | | | | | | | | | 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>

* x86, apic: remove ES7000_IRQ_DELIVERY_MODE and ES7000_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | | 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>

| | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_default template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove IRQ_DEST_MODE / IRQ_DELIVERY_MODEIngo Molnar2009-01-28
| | | | | | | | | | | | | 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>
* x86, genapic: rename int_delivery_mode, et. al.Ingo Molnar2009-01-28
| | | | | | | | | | | | | | | 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>
* x86: clean up apic->apic_id_registered() methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | | 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>
* x86: clean up apic->acpi_madt_oem_check methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | | | | 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>
* x86: remove APIC_INIT / APICFUNC / IPIFUNCIngo Molnar2009-01-28
| | | | | | | | | 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>

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>

The exception is stored thread_info->uaccess_err. The example usage of this framework is below; int func() { int err = 0; get_user_try { get_user_ex(...); get_user_ex(...); : } get_user_catch(err); return err; } Note: get_user_ex() is not clear the value when an exception occurs, it's different from the behavior of __get_user(), but I think it doesn't matter.
