These flags are completely unused. (the in-kernel IRQ balancer has
been removed from the upstream kernel.)

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.

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>
|
|
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.

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.

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.

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

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.

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.

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.

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

Rename genapic-> to apic-> references because in a future chagne we'll
open-code all the indirect calls (instead of obscuring them via macros),

Commit d7b1956fed33d30c4815e848fd7a143722916868 ("DMI: Introduce
dmi_first_match to make the interface more flexible") introduced compile
errors like the following when !CONFIG_DMI
drivers/ata/sata_sil.c: In function 'sil_broken_system_poweroff':
drivers/ata/sata_sil.c:713: error: implicit declaration of function 'dmi_first_match'
drivers/ata/sata_sil.c:713: warning: initialization makes pointer from integer without a cast
We just need a dummy version of dmi_first_match() to fix this all up.

_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.

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.
