Minor cleanup to lend better for physical CPU hotplug. Earlier way of using num_processors as index doesnt fit if CPUs come and go. This makes the code little bit better to read, and helps physical hotplug use the same functions as boot. Reserving CPU0 for BSP is too late to be done in smp_prepare_boot_cpu(). Since logical assignments from MADT is already done via setup_arch()->acpi_boot_init()->parse lapic Signed-off-by:

Touching of the floating point state in a kernel debugger must be NMI-safe, specifically math_state_restore() must be able to deal with being called out of an NMI context. In order to do that reliably, the context switch code must take care to not leave a window open where the current task's TS_USEDFPU flag and CR0.TS could get out of sync. Signed-off-by:

8MB is not really very random, use 1GB (or more with larger page sizes) instead. Also use the low bits of the random generator output now instead of throwing them away. Only enabled on x86-64 right now. Other architectures need to add a suitable STACK_RND_MASK Cc: mingo@elte.hu Signed-off-by:

The upcomming gcc 4.2 got a new option -mtune=generic to tune code for both common AMD and Intel CPUs. Use this option when available for generic kernels. On x86-64 it is used with CONFIG_GENERIC_CPU. On i386 it is enabled with CONFIG_X86_GENERIC. It won't affect the base line CPU support in any ways and also not the minimum supported CPU.

This removes the support for pps. It's completely unused within the kernel and is basically in the way for further cleanups. It should be easier to readd proper support for it after the rest has been converted to NTP4 (where the pps mechanisms are quite different from NTP3 anyway). Signed-off-by:

Chen, Kenneth W authored
There is a bug in direct-io on propagating write error up to the higher I/O layer. When performing an async ODIRECT write to a block device, if a device error occurred (like media error or disk is pulled), the error code is only propagated from device driver to the DIO layer. The error code stops at finished_one_bio(). The aysnc write, however, is supposedly have a corresponding AIO event with appropriate return code (in this case -EIO). Application which waits on the async write event, will hang forever since such AIO event is lost forever (if such app did not use the timeout option in io_getevents call. Regardless, an AIO event is lost). The discovery of above bug leads to another discovery of potential race window with dio->result. The fundamental problem is that dio->result is overloaded with dual use: an indicator of fall back path for partial dio write, and an error indicator used in the I/O completion path. In the event of device error, the setting of -EIO to dio->result clashes with value used to track partial write that activates the fall back path. It was also pointed out that it is impossible to use dio->result to track partial write and at the same time to track error returned from device driver. Because direct_io_work can only determines whether it is a partial write at the end of io submission and in mid stream of those io submission, a return code could be coming back from the driver. Thus messing up all the subsequent logic. Proposed fix is to separating out error code returned by the IO completion path from partial IO submit tracking. A new variable is added to dio structure specifically to track io error returned in the completion path. Signed-off-by:

As Pekka Enberg pointed out, with the if still following the else, you can still get a null uid written to the disk if you specify a default uid= without uid=forget. In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.
