2010-02-25thinkpad-acpi: R52 brightness_mode has been confirmedHenrique de Moraes Holschuh
We can stop pestering users for confirmation of the brightness_mode default for firmware TP-76. While at it, add a few missing comments in that quirk table. Reported-by: Whoopie <whoopie79@gmx.net> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Cc: stable@kernel.org
2010-02-25thinkpad-acpi: document HKEY event 3006Henrique de Moraes Holschuh
Event 0x3006 is used to help power management of the ODD in the UltraBay. The EC generates this event when the ODD eject button is pressed (even if the bay is powered down). Normally, Linux doesn't need this as we keep the SATA link powered up (which wastes power). The EC powers up the bay by itself when the ODD eject button is pressed, and the SATA PHY reports the hotplug. However, we could also power that SATA link down (and for that matter, also power down the Ultrabay) if the ODD is left idle for a while with no disk inside, and use event 0x3006 to know when we need that SATA link powered back up. For now, just stop asking for more information when event 0x3006 is seen, there is no point in pestering users about it anymore.

2010-02-25x86, mrst: Add Kconfig dependencies for MoorestownJacob Pan
The Moorestown platform requires IOAPIC for all interrupts from the south complex, since there is no legacy PIC. Furthermore, Moorestown I/O requires PCI. Moorestown PCI depends on PCI MMCONFIG and DIRECT method to perform device enumeration, as there is no PCI BIOS.

2010-02-25[IA64] build arch/ia64/kernel/acpi-ext.o when CONFIG_ACPIAlex Chiang
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 $2 = 858 Seems like a small price to pay for the benefit of not having to think so hard about the multitude of ia64 configs when reading code/Makefiles.

2010-02-25[IA64] Only build arch/ia64/kernel/acpi.o when CONFIG_ACPIAlex Chiang
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.

2010-02-25ARM: Eliminate decompressor -Dstatic= PIC hackRussell King
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.

2010-02-25x86, numaq: Make CONFIG_X86_NUMAQ depend on CONFIG_PCIPan, Jacob jun
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.

2010-02-25perf probe: Add lazy line matching supportMasami Hiramatsu
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.)

2010-02-25perf probe: Use elfutils-libdw for analyzing debuginfoMasami Hiramatsu
Newer gcc introduces newer & richer debuginfo, and only libdw in elfutils project can support it. So perf probe moves onto elfutils-libdw from libdwarf. Changes in v3: - Cast Dwarf_Addr/Dwarf_Word to uintmax_t for printf-formats. - Recover a sign-prefix which was removed in v2 by mistake. Changes in v2: - Fix a type-casting bug in Makefile. - Cast Dwarf_Addr/Dwarf_Word to unsigned long long for printf-formats.

2010-02-25perf probe: Fix bugs in line range finderMasami Hiramatsu
Fix find_line_range_by_line() to init line_list and remove misconseptional found marking which should be done when real lines are found (if there is no lines probe-able, find_line_range() should return 0).
