Who: Johannes Berg + +---------------------------- + - What: CONFIG_X86_OLD_MCE - When: 2.6.32 - Why: Remove the old legacy 32bit machine check code. This has been - superseded by the newer machine check code from the 64bit port, - but the old version has been kept around for easier testing. Note this - doesn't impact the old P5 and WinChip machine check handlers. - Who: Andi Kleen - - ---------------------------- - +What: lock_policy_rwsem_* and unlock_policy_rwsem_* will not be + exported interface anymore. +When: 2.6.33 +Why: cpu_policy_rwsem has a new cleaner definition making it local to + cpufreq core and contained inside cpufreq.c. Other dependent + drivers should not use it in order to safely avoid lockdep issues. +Who: Venkatesh Pallipadi + +---------------------------- + +What: sound-slot/service-* module aliases and related clutters in + sound/sound_core.c +When: August 2010 +Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR + (14) and requests modules using custom sound-slot/service-* + module aliases. The only benefit of doing this is allowing + use of custom module aliases which might as well be considered + a bug at this point. This preemptive claiming prevents + alternative OSS implementations. + + Till the feature is removed, the kernel will be requesting + both sound-slot/service-* and the standard char-major-* module + aliases and allow turning off the pre-claiming selectively via + CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss + kernel parameter. + + After the transition phase is complete, both the custom module + aliases and switches to disable it will go away. This removal + will also allow making ALSA OSS emulation independent of + sound_core. The dependency will be broken then too. +Who: Tejun Heo diff --cc arch/x86/kernel/cpu/mcheck/mce.c index fdd51b5,325559d..2f5aab2 --- a/arch/x86/kernel/cpu/mcheck/mce.c +++ b/arch/x86/kernel/cpu/mcheck/mce.c @@@ -1236,13 -1235,8 +1245,13 @@@ static void mce_init(void } /* Add per CPU specific workarounds here */ - static int mce_cpu_quirks(struct cpuinfo_x86 *c) -static void __cpuinit mce_cpu_quirks(struct cpuinfo_x86 *c) ++static int __cpuinit mce_cpu_quirks(struct cpuinfo_x86 *c) { + if (c->x86_vendor == X86_VENDOR_UNKNOWN) { + pr_info("MCE: unknown CPU type - not enabling MCE support.\n"); + return -EOPNOTSUPP; + } + /* This should be disabled by the BIOS, but isn't always */ if (c->x86_vendor == X86_VENDOR_AMD) { if (c->x86 == 15 && banks > 4) { @@@ -1345,9 -1334,20 +1354,20 @@@ static void mce_init_timer(void return; setup_timer(t, mcheck_timer, smp_processor_id()); t->expires = round_jiffies(jiffies + *n); - add_timer(t); + add_timer_on(t, smp_processor_id()); } + /* Handle unconfigured int18 (should never happen) */ + static void unexpected_machine_check(struct pt_regs *regs, long error_code) + { + printk(KERN_ERR "CPU#%d: Unexpected int18 (Machine Check).\n", + smp_processor_id()); + } + + /* Call the installed machine check handler for this CPU setup. */ + void (*machine_check_vector)(struct pt_regs *, long error_code) = + unexpected_machine_check; + /* * Called for each booted CPU to set up machine checks. * Must be called with preempt off: diff --cc arch/x86/kernel/irqinit.c index 92b7703,8a194ad..ccf8ab5 --- a/arch/x86/kernel/irqinit.c +++ b/arch/x86/kernel/irqinit.c @@@ -187,10 -187,10 +187,10 @@@ static void __init apic_intr_init(void #ifdef CONFIG_X86_THERMAL_VECTOR alloc_intr_gate(THERMAL_APIC_VECTOR, thermal_interrupt); #endif -#ifdef CONFIG_X86_THRESHOLD +#ifdef CONFIG_X86_MCE_THRESHOLD alloc_intr_gate(THRESHOLD_APIC_VECTOR, threshold_interrupt); #endif - #if defined(CONFIG_X86_NEW_MCE) && defined(CONFIG_X86_LOCAL_APIC) + #if defined(CONFIG_X86_MCE) && defined(CONFIG_X86_LOCAL_APIC) alloc_intr_gate(MCE_SELF_VECTOR, mce_self_interrupt); #endif
