UML: Fix ELF_CORE_COPY_REGS build botch

2007-09-11T01:58:05+00:00

The earlier crash dump fix on x86_64 depended on patches in -mm which are intended for post-2.6.23. Without those, it broke the build when it went into 2.6.23-rc5. This changes the field references in ELF_CORE_COPY_REGS back to those still used in mainline. Signed-off-by: Jeff Dike Signed-off-by: Linus Torvalds

i386: fix a hang on stuck nmi watchdog

2007-09-11T01:57:47+00:00

In the case when an nmi gets stucks the endflag stays equal to zero. This causes the busy looping on other cpus to continue, even though the nmi test is done. On my machine with out the change below the system would hang right after check_nmi_watchdog(). The change below just sets endflag prior to checking if the test was successful or not.

x86_64: Remove CLFLUSH in text_poke()

2007-09-11T01:57:47+00:00

The CLFLUSH for the modified code line in text_poke was supposed to speed up CPU recovery. Unfortunately it seems to cause hangs on some VIA C3s (at least on VIA Esther Model 10 Stepping 9) Remove it. Thanks to Stefan Becker for reporting/testing.

i386: Fix perfctr watchdog on core duo

2007-09-11T01:57:47+00:00

Fix the NMI watchdog on Intel CoreDuo processor where the kernel would get stuck during boot. The issue is related to errata AE49, where the PERFEVTSEL1 counter does not have a working enable bit. Thus it is not possible to use it for NMI. The patch creates a dedicated wd_ops for CoreDuo which falls back to using PERFEVTSEL0. The other Intel processors supporting the architectural PMU will keep on using PERFEVTSEL1 as this allows other subsystems, such as perfmon, to use PERFEVTSEL0 for PEBS monitoring in particular. Bug initially reported by Daniel Walker. AK: Added comments Signed-off-by: Stephane Eranian Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

knfsd: Validate filehandle type in fsid_source

2007-09-11T01:57:47+00:00

fsid_source decided where to get the 'fsid' number to return for a GETATTR based on the type of filehandle. It can be from the device, from the fsid, or from the UUID. It is possible for the filehandle to be inconsistent with the export information, so make sure the export information actually has the info implied by the value returned by fsid_source.

knfsd: Fixed problem with NFS exporting directories which are mounted on.

2007-09-11T01:57:47+00:00

Recent changes in NFSd cause a directory which is mounted-on to not appear properly when the filesystem containing it is exported. *exp_get* now returns -ENOENT rather than NULL and when commit 5d3dbbeaf56d0365ac6b5c0a0da0bd31cc4781e1 removed the NULL checks, it didn't add a check for -ENOENT.
