The attached change defers the initialization of the variables tsk, mm and flags until they are needed. As a result, the code won't crash if a kernel probe is done with a corrupt context and the code will be better optimized.

Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel. The problem is, that in print_worker_info() we try to read the workqueue info via the probe_kernel_read() functions which use pagefault_disable() to avoid crashes like this: probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq)); probe_kernel_read(&wq, &pwq->wq, sizeof(wq)); probe_kernel_read(name, wq->name, sizeof(name) - 1); The problem here is, that the first probe_kernel_read(&pwq) might return zero in pwq and as such the following probe_kernel_reads() try to access contents of the page zero which is read protected and generate a kernel segfault. With this patch we fix the interruption handler to call parisc_terminate() directly only if pagefault_disable() was not called (in which case preempt_count()==0). Otherwise we hand over to the pagefault handler which will try to look up the faulting address in the fixup tables.

Commit 9a46ad6d "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.

Olga reported that file descriptors opened with O_PATH do not work with fstatfs(), found during further development of ksh93's thread support. There is no reason to not allow O_PATH file descriptors here (fstatfs is very much a path operation), so use "fdget_raw()". See commit 55815f70 ("vfs: make O_PATH file descriptors usable for 'fstat()'") for a very similar issue reported for fstat() by the same team.

ARCompact TRAP_S insn used for breakpoints, commits before exception is taken (updating architectural PC). So ptregs->ret contains next-PC and not the breakpoint PC itself. This is different from other restartable exceptions such as TLB Miss where ptregs->ret has exact faulting PC. gdb needs to know exact-PC hence ARC ptrace GETREGSET provides for @stop_pc which returns ptregs->ret vs. EFA depending on the situation. However, writing stop_pc (SETREGSET request), which updates ptregs->ret doesn't makes sense stop_pc doesn't always correspond to that reg as described above. This was not an issue so far since user_regs->ret / user_regs->stop_pc had same value and both writing to ptregs->ret was OK, needless, but NOT broken, hence not observed. With gdb "jump", they diverge, and user_regs->ret updating ptregs is overwritten immediately with stop_pc, which this patch fixes.

This reverts commit 81b5c7bc. Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.

Liu fixed part of this problem and unfortunately I steered him in slightly the wrong direction and so didn't completely fix the problem. The problem is we limit the size of the delalloc range we are looking for to max bytes and then we try to lock that range. If we fail to lock the pages in that range we will shrink the max bytes to a single page and re loop. However if our first page is inside of the delalloc range then we will end up limiting the end of the range to a period before our first page. This is illustrated below [0 -------- delalloc range --------- 256mb] [page] So find_delalloc_range will return with delalloc_start as 0 and end as 128mb, and then we will notice that delalloc_start < *start and adjust it up, but not adjust delalloc_end up, so things go sideways. To fix this we need to not limit the max bytes in find_delalloc_range, but in find_lock_delalloc_range and that way we don't end up with this confusion.
