Nice debugging work. I'd suggest something like the attached (boot tested) patch as the simple fix for now. I expect the benefits from the less synchronized, multiple-in-flight-data global queue will still outweigh the costs of dynamic allocations. But if worst comes to worst then we just go back to a globally synchronous one-at-a-time implementation, but that would be pretty sad! Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides support for the _PSD ACPI object in the Powernow-k8 driver. Although it looks like an invasive patch, most of it is simply the consequence of turning the static acpi_performance_data structure into a pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Break up cifs_setattr further by moving the logic that sets file times and dos attributes into a separate function. This patch also refactors the logic a bit so that when the file is already open then we go ahead and do a SetFileInfo call. SetPathInfo seems to be unreliable when setting times on open files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a server supports unix extensions but does not support POSIX create routines, then the client will create a new inode with a standard SMB mkdir or create/open call and then will set the mode. When it does this, it does not take the setgid bit on the parent directory into account. This patch has CIFS flip on the setgid bit when the parent directory has it. If the share is mounted with "setuids" then also change the group owner to the gid of the parent. This patch should apply cleanly on top of the setattr cleanup patches that I sent a few weeks ago.

So this can't work. Normally, we'd do: pgd = pgd_offset(&init_mm, PHYS_OFFSET); ... pmd = pmd_offset(pgd, PHYS_OFFSET); to get the pmd you want. However, pgd_offset() takes the mm_struct, not the (unattached) pgd we just allocated.
