Revert the dynarray changes. They need more thought and polishing. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-10-16genirq: remove sparse irq codeThomas Gleixner
This code is not ready, but we need to rip it out instead of rebasing as we would lose the APIC/IO_APIC unification otherwise. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-10-16dmar: fix dmar_parse_dev() devices_cnt error condition checkSuresh Siddha
It is possible that, instead of PCI endpoint/sub-hierarchy structures, only IO-APIC/HPET devices may be reported under device scope structures. Fix the devices_cnt error check, which cares about only PCI structures and removes the dma-remapping unit structure (dmaru) when the devices_cnt is zero and include_all flag is not set.

In dmar_dev_scope_init(), functions called under for_each_drhd_unit()/ for_each_rmrr_units() can delete the list entry under some error conditions. So we should use list_for_each_entry_safe() for safe traversal.

2008-10-16dmar: fix using early fixmap mapping for DMAR table parsingYinghai Lu
Very early detection of the DMAR tables will setup fixmap mapping. For parsing these tables later (while enabling dma and/or interrupt remapping), early fixmap mapping shouldn't be used. Fix it by calling table detection routines again, which will call generic apci_get_table() for setting up the correct mapping.

irq_desc[] add CONFIG_HAVE_SPARSE_IRQ to for use condensed array. Get rid of irq_desc[] array assumptions. Preallocate 32 irq_desc, and irq_desc() will try to get more.

2008-10-14rtc-cmos: look for PNP RTC first, then for platform RTCBjorn Helgaas
We shouldn't rely on "pnp_platform_devices" to tell us whether there is a PNP RTC device. I introduced "pnp_platform_devices", but I think it was a mistake. All it tells us is whether we found any PNPBIOS or PNPACPI devices. Many machines have some PNP devices, but do not describe the RTC via PNP. On those machines, we need to do the platform driver probe to find the RTC. We should just register the PNP driver and see whether it claims anything. If we don't find a PNP RTC, fall back to the platform driver probe. This (in conjunction with the arch/x86/kernel/rtc.c patch to add a platform RTC device when PNP doesn't have one) should resolve these issues: http://bugzilla.kernel.org/show_bug.cgi?id=11580 https://bugzilla.redhat.com/show_bug.cgi?id=451188 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: Rafael J.

Once kernel configuration has CONFIG_HID turned on, let also all the specialized drivers for quirky devices to be built (unless CONFIG_EMBEDDED is specified), as usually users don't care that much which driver gives them the functionality, but when they want generic support, they probably want to have support for all the quirky devices as well.

2008-10-14HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula
Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in input_dev->event_lock, which is locked when handling input events. However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.
