2005-09-07[ARM] 2889/1: S3C2410 - Add machine AnubisBen Dooks5-2/+280
Patch from Ben Dooks Add the Simtec Anubis to the list of supported machines in the arch/arm/mach-s3c2410 directory. This ensures the core peripherals are registered, the timer source is configured and the correct power-management is enabled.

2005-09-06[PATCH] Invert sense of SLB class bitDavid Gibson3-10/+11
Currently, we set the class bit in kernel SLB entries, and clear it on user SLB entries. On POWER5, ERAT entries created in real mode have the class bit clear. So to avoid flushing kernel ERAT entries on each context switch, this patch inverts our usage of the class bit, setting it on user SLB entries and clearing it on kernel SLB entries. Booted on POWER5 and G5. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Yes there's software that likes to do this :) and runs as non-root. It's very similar to say VM where you can get CP to provide feedback of the real hardware inside a VM guest.

2005-09-05[PATCH] s390: pfault interrupt raceMartin Schwidefsky1-1/+4
There is a race in pfault_interrupt. That function gets called two times for each pfault notification. Once with a subcode of 0 to indicate that a real page is not available and once with a subcode of 0x80 to indicate that the page is present again. Since the two external interrupts can be delivered on two different cpus the order in which the two calls are made is unpredictable. It is possible that the subcode 0x80 interrupt is completed before the subcode 0x00 interrupt has done the wake_up() call. To avoid calling wake_up() on an already removed task structure proper task structure reference counting is needed. Increase the reference counter in the subcode 0x00 interrupt before setting pfault_wait to zero and return the reference after the wake_up call.

2005-09-05[PATCH] s390: machine check handler bugsMartin Schwidefsky2-55/+174
The new machine check handler still has a few bugs. 1) The system entry time has to be stored in the machine check handler, 2) the machine check return psw may not be stored at the usual place because it might overwrite the return psw of the interrupted context, 3) the return address for the call to s390_handle_mcck in the i/o interrupt handler is not correct, 4) the system call cleanup has to take the different save area of the machine check handler into account, 5) the machine check handler may not call UPDATE_VTIME before CREATE_STACK_FRAME, and 6) the io leave path needs a critical section cleanup to make sure that the TIF_MCCK_PENDING bit is really checked before switching back to user space.

2005-09-05[PATCH] uml: skas0 stubs now check system call return valuesBodo Stroesser8-238/+348
Change syscall-stub's data to include a "expected retval". Stub now checks syscalls retval and aborts execution of syscall list, if retval != expected retval. run_syscall_stub prints the data of the failed syscall, using the data pointer and retval written by the stub to the beginning of the stack. one_syscall_stub is removed, to simplify code, because only some instructions are saved by one_syscall_stub, no host-syscall. Using the stub with additional data (modify_ldt via stub) is prepared also.

2005-09-05[PATCH] uml: increase granularity of host capability checkingBodo Stroesser4-34/+96
This change enables SKAS0/SKAS3 to work with all combinations of /proc/mm and PTRACE_FAULTINFO being available or not. Also it changes the initialization of proc_mm and ptrace_faultinfo slightly, to ease forcing SKAS0 on a patched host. Forcing UML to run without /proc/mm or PTRACE_FAULTINFO by cmdline parameter can be implemented with a setup resetting the related variable.

2005-09-05[PATCH] uml: add host AIO support to block driverJeff Dike4-409/+373
This adds AIO support to the ubd driver. The driver breaks a struct request into IO requests to the host, based on the hardware segments in the request and on any COW blocks covered by the request. The ubd IO thread is gone, since there is now an equivalent thread in the AIO module. There is provision for multiple outstanding requests now. Requests aren't retired until all pieces of it have been completed. The AIO requests have a shared count, which is decremented as IO operations come in until it reaches 0. This can be possibly moved to the request struct - haven't looked at this yet.

2005-09-05[PATCH] uml: TLB operation batchingJeff Dike8-166/+273
This adds VM op batching to skas0. Rather than having a context switch to and from the userspace stub for each address space change, we write a number of operations to the stub data page and invoke a different stub which loops over them and executes them all in one go. The operations are stored as [ system call number, arg1, arg2, ... ] tuples. The set is terminated by a system call number of 0. Single operations, i.e. page faults, are handled in the old way, since that is slightly more efficient. For a kernel build, a minority (~1/4) of the operations are part of a set. These sets averaged ~100 in length, so for this quarter, the context switching overhead is greatly reduced.
