2009-02-17x86, apic: clean up the cpu_2_logical_apiciddeclarationIngo Molnar
extern declarations were scattered in 4 files - consolidate them into apic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: clean up arch/x86/kernel/bigsmp_32.cIngo Molnar
Impact: cleanup - remove unnecessary indirections that were artifacts of the subarch code - clean up include file section - clean up various small details Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: remove stale references to APIC_DEFINITIONIngo Molnar
Impact: cleanup APIC_DEFINITION was a hack from the x86 subarch times, it has no meaning anymore - remove it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: remove duplicate asm/apic.h inclusionsIngo Molnar
Impact: cleanup Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: remove genapic.hIngo Molnar
Impact: cleanup Remove genapic.h and remove all references to it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: merge genapic.h into apic.hIngo Molnar
Impact: cleanup Reduce the number of include files to worry about. Also, most of the users of APIC facilities had to include genapic.h already, which embedded apic.h, so the distinction was meaningless. [ include apic.h from genapic.h for compatibility. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17remove: genapic prepareIngo Molnar
Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: fix build fallout of genapic changesIngo Molnar
- make oprofile build - select X86_X2APIC from X86_UV - it relies on it - export genapic for oprofile modular build Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86: fold apic_ops into genapicYinghai Lu
Impact: cleanup make it simpler, don't need have one extra struct. v2: fix the sgi_uv build Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86: add x2apic configYinghai Lu
Impact: cleanup so could deselect x2apic and INTR_REMAP will select x2apic Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-16x86: make APIC_init_uniprocessor() more like smp_prepare_cpus()Yinghai Lu
Impact: cleanup 1. move localise_nmi_watchdog() later 2. change setup_boot_APIC_clock() to setup_boot_clock() for 64-bit Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-16x86: pre init pirq_entries[]Yinghai Lu
Impact: cleanup set default value early - this allows the removal of a number of dynamic initialization codepaths, and an #ifdef. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-16x86, xen: do multicall callbacks with interrupts disabledJeremy Fitzhardinge
We can't call the callbacks after enabling interrupts, as we may get a nested multicall call, which would cause a great deal of havok. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-16x86, xen: degrade BUG to WARN when multicall failsJeremy Fitzhardinge

2009-02-16x86, xen: short-circuit tests for dom0Jeremy Fitzhardinge
When testing for a dom0/initial/privileged domain, make sure the predicate evaluates to a compile-time 0 if CONFIG_XEN_DOM0 isn't enabled. This will make most of the dom0 code evaporate without much more effort. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-15x86: fix typo in filter_cpuid_features()Yinghai Lu
Impact: fix wrong disabling of cpu features an amd system got this strange output: CPU: CPU feature monitor disabled due to lack of CPUID level 0x5 but in /proc/cpuinfo I have: cpuid level : 5 on intel system: CPU: CPU feature monitor disabled due to lack of CPUID level 0x5 CPU: CPU feature dca disabled due to lack of CPUID level 0x9 but in /proc/cpuinfo i have: cpuid level : 11 Tt turns out there is a typo, and we should use level member in df.

2009-02-14x86, olpc: fix model detection without OFWChris Ball
Impact: fix "garbled display, laptop is unusable" bug Commit e51a1ac2dfca9ad869471e88f828281db7e810c0 ("x86, olpc: fix endian bug in openfirmware workaround") breaks model comparison on OLPC; the value 0xc2 needs to be scaled up by olpc_board(). The pre-patch version was wrong, but accidentally worked anyway (big-endian 0xc2 is big enough to satisfy all other board revisions, but little endian 0xc2 is not).

Commit 976e8f677e42757e5586ea04a9ac8bb8ddaa037e ("x86: asm/io.h: unify virt_to_phys/phys_to_virt") changed the return of virt_to_phys from long to phys_addr_t which is unsigned long long on a PAE platform. So, I could suggest a fix below since isa addresses may never be above 32 bits. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-13User namespaces: Only put the userns when we unhash the uidSerge E. Hallyn
uids in namespaces other than init don't get a sysfs entry. For those in the init namespace, while we're waiting to remove the sysfs entry for the uid the uid is still hashed, and alloc_uid() may re-grab that uid without getting a new reference to the user_ns, which we've already put in free_user before scheduling remove_user_sysfs_dir().

2009-02-13ASoC: Only register AC97 bus if it's not done alreadyMark Brown
ASoC supports both explicit codec drivers for AC97 devices and a simple driver which uses the standard ALSA AC97 framework for codec support. When used with the generic AC97 codec support that will provide the ad hoc AC97 device for drivers like touchscreens to attach to so the core shouldn't do so.

Added the helper function snd_hda_multi_out_dig_cleanup() to clean up the digital outputs with multi setup. This call is needed in cases the codec supports multiple digital outputs as slaves. Otherwise the slave widgets aren't properly cleaned up. For a single digital output (e.g. in patch_conexant.c), this call isn't needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
