gcc 3 is too braindamaged to be able to compile static_cpu_has() -- apparently it can't tell that a constant passed to an inline function is still a constant -- so if we're using gcc 3, just use the dynamic test. This is bad for performance, but if you care about performance, don't use an ancient, known-to-optimize-poorly compiler. Reported-and-tested-by:

Reserve_memtype will allocate memory for new memtype, but in free_memtype, after the memtype erased from rbtree, the memory is not freed. Changes since V1: make rbt_memtype_erase return erased memtype so that it can be freed in free_memtype. [ hpa: not for -stable: 2.6.34 and earlier not affected ] Signed-off-by:

Fix the following warning: "WARNING: arch/x86/kernel/built-in.o(.exit.text+0x72): Section mismatch in reference from the function powernowk8_exit() to the variable .cpuinit.data:cpb_nb The function __exit powernowk8_exit() references a variable __cpuinitdata cpb_nb. This is often seen when error handling in the exit function uses functionality in the init path. The fix is often to remove the __cpuinitdata annotation of cpb_nb so it may be used outside an init section." Cc: <stable@kernel.org> Reported-by:

Bits set in cpu_possible_mask prior to the execution of prefill_possible_map() (i.e. when parsing ACPI or MPS tables) would prevent the SMP alternatives logic from switching to UP mode, plus unnecessary setup of per-CPU data for CPUs that can never come online. Additionally, without CONFIG_HOTPLUG_CPU disabled CPUs can never come online, and hence setting cpu_possible_mask bits for them is again a simple waste of resources. Signed-off-by:

When the SMP kernel decides to crash_kexec() the local APICs may have pending interrupts in their vector tables. The setup routine for the local APIC has a deficient mechanism for clearing these interrupts, it only handles interrupts that has already been dispatched to the local core for servicing (the ISR register) safely, it doesn't consider lower prioritized queued interrupts stored in the IRR register. If you have more than one pending interrupt within the same 32 bit word in the LAPIC vector table registers you may find yourself entering the IO APIC setup with pending interrupts left in the LAPIC. This is a situation for wich the IO APIC setup is not prepared. Depending of what/which interrupt vector/vectors are stuck in the APIC tables your system may show various degrees of malfunctioning. That was the reason why the check_timer() failed in our system, the timer interrupts was blocked by pending interrupts from the old kernel when routed trough the IO APIC. Additional comment from Jiri Bohac: ============== If this should go into stable release, I'd add some kind of limit on the number of iterations, just to be safe from hard to debug lock-ups: +if (loops++ > MAX_LOOPS) { + printk("LAPIC pending clean-up") + break; +} while (queued); with MAX_LOOPS something like 1E9 this would leave plenty of time for the pending IRQs to be cleared and would and still cause at most a second of delay if the loop were to lock-up for whatever reason. [trenn@suse.de: V2: Use tsc if avail to bail out after 1 sec due to possible virtual apic_read calls which may take rather long (suggested by: Avi Kivity <avi@redhat.com>) If no tsc is available bail out quickly after cpu_khz, if we broke out too early and still have irqs pending (which should never happen?) we still get a WARN_ON... V3: - Fixed indentation -> checkpatch clean - max_loops must be signed V4: - Fix typo, mixed up tsc and ntsc in first rdtscll() call V5: Adjust WARN_ON() condition to also catch error in cpu_has_tsc case] Cc: <jbohac@novell.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Kerstin Jonsson <kerstin.jonsson@ericsson.com> Cc: Avi Kivity <avi@redhat.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Tested-by:

This reverts commit 03ceedea, since it breaks resume from suspend-to-ram on Rafael's Acer Ferrari One. NetworkManager thinks everything is ok, but it can't connect to the AP to get an IP address after the resume. In fact, it even breaks resume for non-ath9k chipsets: reverting it also fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes says: "Indeed, this patch needs to be reverted. That mac80211 change is wrong and completely unnecessary." Reported-and-requested-by:

commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone update in a very subtle way. To avoid the direct access to timekeeping internals it adds the timezone delta to the current time with timespec_add_safe(). This works nicely when the timezone delta is > 0. If timezone delta is < 0 then the wrap check in timespec_add_safe() triggers and timespec_add_safe() returns TIME_MAX and screws up timekeeping completely. The comment above timespec_add_safe() says: It's assumed that both values are valid (>= 0) Add the timezone seconds adjustment directly. Reported-by:
