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.

The NUMAQ initialization sets x86_init.pci.init to pci_numaq_init,
which obviously isn't defined if CONFIG_PCI isn't defined. This
dependency was implicit in the past, because pci_numaq_init was
invoked from arch/x86/pci/legacy.c, which itself was conditioned on
CONFIG_PCI.
I suspect that no NUMA-Q machines without PCI were ever built, so
instead of complicating the code by adding #ifdefs or stub functions,
just disable this bit of the configuration space.

Right now, we assume that the hardware rfkill switch on Dells toggles all
radio devices. In fact, this can be configured in the BIOS and so right
now we may mark a device as hardware killed even when it isn't. Add code
to query the devices controlled by the switch, and use this when
determining the hardware kill state of a radio.

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.

The "hardware" switch is tied directly to a BIOS interface that will
connect and disconnect the hardware from the bus.
If you use the software interface to request the BIOS to make these
changes, the HW switch will be in an inconsistent state and LEDs may not
reflect the state of the HW.

Add lazy line matching support for specifying new probes.
This also changes the syntax of perf probe a bit. Now
perf probe accepts one of below probe event definitions.
1) Define event based on function name
[EVENT=]FUNC[@SRC][:RLN|+OFF|%return|;PTN] [ARG ...]
2) Define event based on source file with line number
[EVENT=]SRC:ALN [ARG ...]
3) Define event based on source file with lazy pattern
[EVENT=]SRC;PTN [ARG ...]
- New lazy matching pattern(PTN) follows ';' (semicolon). And it
must be put the end of the definition.
- So, @SRC is no longer the part which must be put at the end
of the definition.
Note that ';' (semicolon) can be interpreted as the end of
a command by the shell. This means that you need to quote it.
(anyway you will need to quote the lazy pattern itself too,
because it may contains other sensitive characters, like
'[',']' etc.).
Lazy matching
-------------
The lazy line matching is similar to glob matching except
ignoring spaces in both of pattern and target.
e.g.
'a=*' can matches 'a=b', 'a = b', 'a == b' and so on.
This provides some sort of flexibility and robustness to
probe point definitions against minor code changes.
(for example, actual 10th line of schedule() can be changed
easily by modifying schedule(), but the same line matching
'rq=cpu_rq*' may still exist.)
Changes in v3:
- Cast Dwarf_Addr to uintmax_t for printf-formats.
Changes in v2:
- Cast Dwarf_Addr to unsigned long long for printf-formats.

Introduce x86 arch-specific optimization code, which supports
both of x86-32 and x86-64.
This code also supports safety checking, which decodes whole of
a function in which probe is inserted, and checks following
conditions before optimization:
- The optimized instructions which will be replaced by a jump instruction
don't straddle the function boundary.
- There is no indirect jump instruction, because it will jumps into
the address range which is replaced by jump operand.
- There is no jump/loop instruction which jumps into the address range
which is replaced by jump operand.
- Don't optimize kprobes if it is in functions into which fixup code will
jumps.
This uses text_poke_multibyte() which doesn't support modifying
code on NMI/MCE handler. However, since kprobes itself doesn't
support NMI/MCE code probing, it's not a problem.
Changes in v9:
- Use *_text_reserved() for checking the probe can be optimized.
- Verify jump address range is in 2G range when preparing slot.
- Backup original code when switching optimized buffer, instead of
preparing buffer, because there can be int3 of other probes in
preparing phase.
- Check kprobe is disabled in arch_check_optimized_kprobe().
- Strictly check indirect jump opcodes (ff /4, ff /5).
Changes in v6:
- Split stop_machine-based jump patching code.
- Update comments and coding style.
Changes in v5:
- Introduce stop_machine-based jump replacing.

Introduce kprobes jump optimization arch-independent parts.
Kprobes uses breakpoint instruction for interrupting execution
flow, on some architectures, it can be replaced by a jump
instruction and interruption emulation code. This gains kprobs'
performance drastically.
To enable this feature, set CONFIG_OPTPROBES=y (default y if the
arch supports OPTPROBE).
Changes in v9:
- Fix a bug to optimize probe when enabling.
- Check nearby probes can be optimize/unoptimize when disarming/arming
kprobes, instead of registering/unregistering. This will help
kprobe-tracer because most of probes on it are usually disabled.
Changes in v6:
- Cleanup coding style for readability.
- Add comments around get/put_online_cpus().
Changes in v5:
- Use get_online_cpus()/put_online_cpus() for avoiding text_mutex
deadlock.
