| * [IA64] Fix kernel hangup in kdump on INITKenji Kaneshige2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the problem that kdump on INIT hung up if kdump kernel image is not configured. The kdump_init_notifier() on monarch CPU stops its operation at DIE_INIT_MONARCH_LEAVE time if the kdump kernel image is not configured. On the other hand, kdump_init_notifier() on non-monarch CPUs get into spin because they don't know the fact the monarch stops its operation. This is the cause of this problem. To fix this problem, we need to check the kdump kernel image at the top of the kdump_init_notifier() function.

| | | | | | | | | | | | | | | | | | | | Fix the problem that kdump on INIT causes a kernel panic if kdump kernel image is not configured. The cause of this problem is machine_kexec_on_init() is using printk in INIT context. It should use ia64_mca_printk() instead.

| * [IA64] Fix race when multiple cpus go through MCARuss Anderson2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Additional testing uncovered a situation where the MCA recovery code could hang due to a race condition. According to the SAL spec, SAL sends a rendezvous interrupt to all but the first CPU that goes into MCA. This includes other CPUs that go into MCA at the same time. Those other CPUs will go into the linux MCA handler (rather than the slave loop) with the rendezvous interrupt pending. When all the CPUs have completed MCA processing and the last monarch completes, freeing all the CPUs, the CPUs with the pended rendezvous interrupt then go into the ia64_mca_rendez_int_handler(). In ia64_mca_rendez_int_handler() the CPUs get marked as rendezvoused, but then leave the handler (due to no MCA). That leaves the CPUs marked as rendezvoused _before_ the next MCA event. When the next MCA hits, the monarch will mistakenly believe that all the CPUs are rendezvoused when they are not, opening up a window where a CPU can get stuck in the slave loop. This patch avoids leaving CPUs marked as rendezvoused when they are not. Signed-off-by: Russ Anderson <rja@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * [IA64] Remove needless delay in MCA rendezvousRuss Anderson2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing the MCA recovery code, noticed that some machines would have a five second delay rendezvousing cpus. What was happening is that ia64_wait_for_slaves() would check to see if all the slave CPUs had rendezvoused. If any had not, it would wait 1 millisecond then check again. If any CPUs had still not rendezvoused, it would wait 5 seconds before checking again. On some configs the rendezvous takes more than 1 millisecond, causing the code to wait the full 5 seconds, even though the last CPU rendezvoused after only a few milliseconds. The fix is to check every 1 millisecond to see if all the cpus have rendezvoused. After 5 seconds the code concludes the CPUs will never rendezvous (same as before). The MCA code is, by definition, not performance critical, but a needless delay of 5 seconds is senseless. The 5 seconds also adds up quickly when running the error injection code in a loop. This patch both simplifies the code and removes the needless delay. Signed-off-by: Russ Anderson <rja@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * [IA64] add driver for ACPI methods to call native firmwareBjorn Helgaas2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver for HPQ5001 devices installs a global ACPI OpRegion handler. AML methods can use this OpRegion to call native firmware entry points. ACPI does not define a mechanism for AML methods to call native firmware interfaces such as PAL or SAL. This OpRegion handler adds such a mechanism. After the handler is installed, an AML method can call native firmware by storing the arguments and firmware entry point to specific offsets in the OpRegion. When AML reads the "return value" offset from the OpRegion, this handler loads up the arguments, makes the firmware call, and returns the result.

The callback salinfo_cpu_callback() is incorrectly marked __devinit -- it must be __cpuinit instead. * topology.c: cache_sysfs_init() is only called at device_initcall() time so marking it as __cpuinit is wrong and wasteful. It should be unconditionally __init. Also cleanup reference to hotplug notifier callback function from this function and replace with cache_add_dev(), which could also enable us to use other tricks to replace __cpuinit{data} annotations, as recently discussed on this list. cache_shared_cpu_map_setup() is only ever called from __cpuinit-marked functions hence both its definitions (SMP or !SMP) are candidates for __cpuinit itself. Also all_cpu_cache_info can be __cpuinitdata because only referenced from __cpuinit code.

* | | x86: force timer broadcast on late AMD C1E detectionThomas Gleixner2007-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Check the C1E caused APIC timer disable, when the secondary APIC timer is initialized. If the boot CPU APIC timer was registered as a functional clock event device, then fix this up and utilize the CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already registered boot CPU APIC timer into broadcast mode. Tested by force injecting the failure mode. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Now that we use physical addresses for the INO buckets, we can allocate them dynamically for VIRQs and encode the cookies as ~__pa(bucket). This allows us to test for and decode the cookie with a simple: brlz $reg1, 1f xnor $reg1, %g0, $reg2 sequence. This works because bit 64 is never set in traditional INO vectors, and it is also never set in a physical address. So xnor'ing the physical address of the bucket always gives us a negative number, and thus a unique condition we can test cheaply. Inspired by ideas from Greg Onufer. Signed-off-by: David S.

This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply a consistent format to vmlinux.lds. The file is now to some degree readable. In addition move several labels inside the braces such that they reflect the actual start address of a section. Without this the label would not reflect if ld added alignment.

When going through the file fixed the following: - Use PAGE_SIZE as replacement for hardcoded 4096 - Moves label definitions inside {} to avoid ld alignment that may be added between label and section Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no good reason for board platform code to mess with the ROOT_DEV. Remove it from all in-tree platforms except powermac This is a follow on to commit 745e1027751acbc1f14f8bbef378b491242b9c83. The original patch had this change to lite5200.c, but it got dropped in the psycho madness that is the 2.6.24 merge window.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch the tps65010 driver into a "new-style" I2C driver, and convert all of its in-tree users (board support for OSK, H2, H3) accordingly. That accounts for most of the board-specific code in this driver; the rest of that code is now moved into board-specific initcalls. Also remove some of the many now-superfluous #includes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.

With that and with Stephen's patch ("[PATCH net-2.6] uml: hard_header fix") we have uml allmodconfig building both on i386 and amd64.
