* [PATCH] JBD: 16T fixesEric Sandeen2006-09-27
| | | | | | | | | | | | | | | | | | | These are a few places I've found in jbd that look like they may not be 16T-safe, or consistent with the use of unsigned longs for block containers. Problems here would be somewhat hard to hit, would require journal blocks past the 8T boundary, which would not be terribly common. Still, should fix. (some of these have come from the ext4 work on jbd as well). I think there's one more possibility that the wrap() function may not be safe IF your last block in the journal butts right up against the 232 block boundary, but that seems like a VERY remote possibility, and I'm not worrying about it at this point.

If we have a pci_driver multithread_probe flag to inherit you can turn it on for one driver at a time. From playing so far however I think we need a different model at the device layer which serializes until the called probe function says "ok you can start another one now". That would need some kind of flag and semaphore plus a helper function. Anyway in the absence of that this is a starting point to usefully play with this stuff Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

When a root port service device is probed, the aerdrv will call request_irq to register irq handler for AER error interrupt. When a device sends an PCI-Express error message to the root port, the root port will trigger an interrupt, by either MSI or IO-APIC, then kernel would run the irq handler. The handler collects root error status register and schedules a work. The work will call the core part to process the error based on its type (Correctable/non-fatal/fatal). As for Correctable errors, the patch chooses to just clear the correctable error status register of the device. As for the non-fatal error, the patch follows generic PCI error handler rules to call the error callback functions of the endpoint's driver. If the device is a bridge, the patch chooses to broadcast the error to downstream devices. As for the fatal error, the patch resets the pci-express link and follows generic PCI error handler rules to call the error callback functions of the endpoint's driver. If the device is a bridge, the patch chooses to broadcast the error to downstream devices. Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

It is used in a generic quirk quirk_msi_ht_cap() to check whether MSI is enabled on hypertransport chipset, and a nVidia specific quirk quirk_nvidia_ck804_msi_ht_cap() where two 2 HT MSI mappings have to be checked.

* | | [MIPS] fstatat syscall namesRichard Sandiford2006-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS is the only port to call its fstatat()-related syscalls "__NR_fstatat". Now I can see why that might be seen as every other port being wrong, but I think for o32, it is at best confusing. __NR_fstat provides a plain (32-bit) stat while __NR_fstatat provides a 64-bit stat. Changing the name to __NR_fstatat64 would make things more explicit, match x86, and make the glibc port slightly easier. The current name is more appropriate for n32 and n64, but it would be appropriate for other 64-bit targets too, and those targets have chosen to call it __NR_newfstatat instead. Using the same name for MIPS would again be more consistent and make the glibc port slightly easier. I'm not wedded to this idea if the current names are preferred, but FWIW...

This allows consistent reporting of CPU thermal throttle events. After ACK'ing the interrupt, if the event is current, the user (p4.c/mce_intel.c) calls therm_throt_process to log (and rate limit) the event.

| * [PATCH] Add 64bit jiffies compares (for use with get_jiffies_64)Dmitriy Zavin2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current time_before/time_after macros will fail typechecks when passed u64 values (as returned by get_jiffies_64()). On 64bit systems, this will just result in a warning about mismatching types without explicit casts, but since unsigned long and u64 (unsigned long long) are of same size, it will still work. On 32bit systems, a long is 32bits, so the value from get_jiffies_64() will be truncated by the cast and thus lose all the precision gained by 64bit jiffies.

| * [PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing ↵Andi Kleen2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conf1 Some buggy systems can machine check when config space accesses happen for some non existent devices. i386/x86-64 do some early device scans that might trigger this. Allow pci=noearly to disable this. Also when type 1 is disabling also don't do any early accesses which are always type1. This moves the pci= configuration parsing to be a early parameter. I don't think this can break anything because it only changes a single global that is only used by PCI.

| * [PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinderJan Beulich2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current gcc generates calls not jumps to noreturn functions. When that happens the return address can point to the next function, which confuses the unwinder. This patch works around it by marking asynchronous exception frames in contrast normal call frames in the unwind information. Then teach the unwinder to decode this. For normal call frames the unwinder now subtracts one from the address which avoids this problem. The standard libgcc unwinder uses the same trick. It doesn't include adjustment of the printed address (i.e. for the original example, it'd still be kernel_math_error+0 that gets displayed, but the unwinder wouldn't get confused anymore. This only works with binutils 2.6.17+ and some versions of H.J.Lu's 2.6.16 unfortunately because earlier binutils don't support .cfi_signal_frame [AK: added automatic detection of the new binutils and wrote description] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de>

| * [PATCH] Fix idle notifiersAndi Kleen2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously exit_idle would be called more often than enter_idle Now instead of using complicated tests just keep track of it using the per CPU variable as a flip flop. I moved the idle state into the PDA to make the access more efficient. Original bug report and an initial patch from Stephane Eranian, but redone by AK.
