| x86/pci: update pirq_enable_irq() to setup io apic routing
|
| So we can set io apic routing only when enabling the device irq.
wrecked his opteron box, ata1 interrupts fail to get through.
ata1 is using irq 11:
[ 1.451839] sata_svw 0000:01:0e.0: version 2.3
[ 1.456333] sata_svw 0000:01:0e.0: PCI INT A -> GSI 11 (level, low) -> IRQ 11
[ 1.463639] scsi0 : sata_svw
[ 1.466949] scsi1 : sata_svw
[ 1.470022] scsi2 : sata_svw
[ 1.473090] scsi3 : sata_svw
[ 1.476112] ata1: SATA max UDMA/133 mmio m8192@0xff3fe000 port 0xff3fe000 irq 11
[ 1.483490] ata2: SATA max UDMA/133 mmio m8192@0xff3fe000 port 0xff3fe100 irq 11
[ 1.490870] ata3: SATA max UDMA/133 mmio m8192@0xff3fe000 port 0xff3fe200 irq 11
[ 1.498247] ata4: SATA max UDMA/133 mmio m8192@0xff3fe000 port 0xff3fe300 irq 11
that pin is overlapped with pin with legacy ones.
We should not set bits in pin_programmed here, so that those bit could
be set later via io_apic_set_pci_routing().

Len expressed concern that the update_mptable feature has
side-effects on the ACPI code.
Make it sure explicitly that the code only ever gets called if
the (default disabled) update_mptable boot quirk option is
disabled.

To get all device irq routing and to save them.
This is basically an implicit pci=routeirq enablement if (and on if)

according to Ingo, io_apic irq-setup related functions have too many
parameters with a repetitive signature.
So reduce related funcs to get less params by passing a pointer
to a newly defined io_apic_irq_attr structure.
v2: io_apic_irq ==> irq_attr
triggering ==> trigger
v3: add set_io_apic_irq_attr

Ed found that on 32-bit, boot_cpu_physical_apicid is not read right,
when the mptable is broken.
Interestingly, actually three paths use/set it:
1. acpi: at that time that is already read from reg
2. mptable: only read from mptable
3. no madt, and no mptable, that use default apic id 0 for 64-bit, -1 for 32-bit
so we could read the apic id for the 2/3 path. We trust the hardware
register more than we trust a BIOS data structure (the mptable).
We can also avoid the double set_fixmap() when acpi_lapic
is used, and also need to move cpu_has_apic earlier and
call apic_disable().
Also when need to update the apic id, we'd better read and
set the apic version as well - so that quirks are applied precisely.
v2: make path 3 with 64bit, use -1 as apic id, so could read it later.
v3: fix whitespace problem pointed out by Ed Swierk
v5: fix boot crash

So we can set io apic routing only when enabling the device irq.
This is advantageous for IRQ descriptor allocation affinity: if we set up
the IO-APIC entry later, we have a chance to allocate the IRQ descriptor
later and know which device it is on and can set affinity accordingly.

The patch to call mp_config_acpi_gsi() from the ACPI IRQ registration
code never got mainline because there were open discussions about it.
This call is needed to properly update the kernel's copy of the mptable,
when the update_mptable boot parameter is needed.
Now that the dust has settled with the APIC unification, and since there
were no objections when the patch was re-submitted, try this again.

We already have a per cpu vector on 32-bit via recent changes, and
don't need this trick any more (which trick obfuscates the real GSI

Tim Starling reported that crashdump will panic with kernel compiled
with CONFIG_KEXEC_JUMP due to null pointer deference in
machine_kexec_32.c: machine_kexec(), when deferencing
kexec_image. Refering to:
http://bugzilla.kernel.org/show_bug.cgi?id=13265
This patch fixes the BUG via replacing global variable reference:
kexec_image in machine_kexec() with local variable reference: image,
which is more appropriate, and will not be null.
Same BUG is in machine_kexec_64.c too, so fixed too in the same way.

With the introduction of the .brk section, special care must be taken
that no unused page table entries remain if _brk_end and _end are
separated by a 2M page boundary. cleanup_highmap() runs very early and
hence cannot take care of that, hence potential entries needing to be
removed past _brk_end must be cleared once the brk allocator has done
its job.

From: Bruce Ashfield <bruce.ashfield@windriver.com>
To fully support the armv7-a instruction set/optimizations, support
for the R_ARM_MOVW_ABS_NC and R_ARM_MOVT_ABS relocation types is
required.
The MOVW and MOVT are both load-immediate instructions, MOVW loads 16
bits into the bottom half of a register, and MOVT loads 16 bits into the
top half of a register.
The relocation information for these instructions has a full 32 bit
value, plus an addend which is stored in the 16 immediate bits in the
instruction itself. The immediate bits in the instruction are not
contiguous (the register # splits it into a 4 bit and 12 bit value),
so the addend has to be extracted accordingly and added to the value.
The value is then split and put into the instruction; a MOVW uses the
bottom 16 bits of the value, and a MOVT uses the top 16 bits.

The mem= option will truncate the memory map at a specified address so
it's not possible to register nodes with memory beyond the e820 upper
bound.
unparse_node() is only called when then node had memory associated with
it, although with the mem= option it is no longer addressable.

This build failure:
arch/powerpc/sysdev/mpic.c:810: error: conflicting types for 'mpic_set_affinity'
arch/powerpc/sysdev/mpic.h:39: error: previous declaration of 'mpic_set_affinity' was here
make[2]: *** [arch/powerpc/sysdev/mpic.o] Error 1
make[2]: *** Waiting for unfinished jobs....
Triggers because the function prototype was not updated when the
function call signature got changed by:
d5dedd4: irq: change ->set_affinity() to return status

The i.MX31 ARM11 core is not a v6K core. Disable this option as it
is incompatible with non v6K cores.

Before this patch I got the following line in my dmesg:
[ 0.000000] BUG: mapping for 0xd4000000 at 0xeb000000 overlaps vmalloc space
VMALLOC_END is 0xf4000000 and there are the following other mappings
defined for mx27ads:
(0xa0500000,+0x00001000) maps to 0xffff0000
(0x10000000,+0x00100000) maps to 0xf4000000
(0x80000000,+0x00100000) maps to 0xf4100000
(0xd8000000,+0x00100000) maps to 0xf4200000
So map PBC to 0xf4300000.

On i.MX31 I sometimes get spurious interrupts. There is no need
to crash the whole system when this happens. Instead, silently
ignore it.

We want to have a mx31_defconfig file that builds a kernel that is able
to boot on all support mx31 systems and thus also can be better tested
by automatic build scripts. For these reasons, this config file is not
needed anymore.

The sequence
imx_dma_request()
imx_dma_enable()
imx_dma_free()
left the dma channel in_use mode and did not release the timer.
