Simplify the makefile slightly by always building acpi-ext.o when
CONFIG_ACPI is turned on.
Yes, this adds a little bloat to the other configs, but not much:
text data bss dec hex filename
839 41 0 880 370 arch/ia64/kernel/acpi-ext.o
Before:
text data bss dec hex filename
10952753 1299212 1334241 13586206 cf4f1e vmlinux
After:
text data bss dec hex filename
10953739 1299084 1334241 13587064 cf5278 vmlinux
(gdb) p 13587064 - 13586206

The following commit broke the ia64 sim_defconfig build:
3b2b84c0b81108a9a869a88bf2beeb5a95d81dd1
ACPI: processor: driver doesn't need to evaluate _PDC
This is because it added:
+#include <acpi/processor.h>
To arch/ia64/kernel/acpi.c. Unfortunately, the ia64_simdefconfig does
not turn on CONFIG_ACPI, and we get build errors.
The fix described in $subject seems to be the most sensible way to
untangle the mess.
The other issue is that acpi_get_sysname() is required for all configs,
most of which define CONFIG_ACPI, but are not CONFIG_IA64_GENERIC. Turn
it into an inline to cover the "non generic" ia64 configs; to prevent
a duplicate definition build error, we need to wrap the definition in
acpi.o inside an #ifdef.
Finally, move the pm_idle and pm_power_off exports into process.c (which
is always built), similar to other architectures, and allow the sim
defconfig to link.

Currently, only those mem resources are validated which are already
registered at the time the first PCMCIA card is inserted. As we can
only validate resources immediately after card insert, store
"registered" mem resources in mem_db, and only upon validation move
them to mem_db_valid. When allocationg mem resources, mem_db_valid is
then preferred to mem_db.

We used to build decompressors with -Dstatic= to avoid any local data
being generated. The problem is that local data generates GOTOFF
relocations, which means we can't relocate the data relative to the
text segment.
Global data, on the other hand, goes through the GOT, and can be
relocated anywhere.
Unfortunately, with the new decompressors, this presents a problem
since they declare static data within functions, and this leads to
stack overflow.
Fix this by separating out the decompressor code into a separate file,
and removing 'static' from BSS data in misc.c.
Also, discard the .data section - this means that should we end up
with read/write initialized data, the decompressor will fail to link
and the problem will be obvious.

radio devices. In fact, this can be configured in the BIOS and so right

Calls to communicate with system firmware via a SMI (using dcdbas)
need to use a buffer that has a physical address of 4GB or less.
Currently the dell-laptop driver does not guarantee this, and when the
buffer address is higher than 4GB, the address is truncated to 32 bits
and the SMI handler writes to the wrong memory address.

commit ff097ddd4 (x86/PCI: MMCONFIG: manage pci_mmcfg_region as a
list, not a table) introduced a nasty memory corruption when
pci_mmcfg_list is empty.
pci_mmcfg_check_end_bus_number() dereferences pci_mmcfg_list.prev even
when the list is empty. The following write hits some variable near to
pci_mmcfg_list.
Further down a similar problem exists, where cfg->list.next is
dereferenced unconditionally and a comparison with some variable near
to pci_mmcfg_list happens.
Add a check for the last element into the for_each_entry() loop and
remove all the other crappy logic which is just a leftover of the old
array based code which was replaced by the list conversion.

Currently the i.MX FIQ handler is reporting periods as elapsed based
purely on a timer running in the CPU. This means that any clock
mismatch between the CPU and the audio subsystem can result in the
status reported to applications drifting away from the actual status
of the hardware. This is particularly likely at present since the
SSI driver is only capable of operating in slave mode so it's very
likely that the interface will be clocked from a different source.
Instead check the offset reported by the FIQ and only notify when we
have transferred at least one period, re-firing the timer if we didn't
do so. Also factor out the calculation of the timer expiry time for
make it a bit easier to experiment with.
Note that this only improves the situation, problems can still be
triggered.

GCC 4.5 introduces behavior that forces the alignment of structures to
use the largest possible value. The default value is 32 bytes, so if
some structures are defined with a 4-byte alignment and others aren't
declared with an alignment constraint at all - it will align at 32-bytes.
For things like the ftrace events, this results in a non-standard array.
When initializing the ftrace subsystem, we traverse the _ftrace_events
section and call the initialization callback for each event. When the
structures are misaligned, we could be treating another part of the
structure (or the zeroed out space between them) as a function pointer.
This patch forces the alignment for all the ftrace_event_call structures
to 4 bytes.
Without this patch, the kernel fails to boot very early when built with
gcc 4.5.
It's trivial to check the alignment of the members of the array, so it
might be worthwhile to add something to the build system to do that
automatically. Unfortunately, that only covers this case. I've asked one
of the gcc developers about adding a warning when this condition is seen.
