Some archs such as blackfin, would like to have an arch specific probe_kernel_read() and probe_kernel_write() implementation which can fall back to the generic implementation if no special operations are needed.

drm_pci_alloc() has input of address mask for setting pci dma mask on the device, which should be properly setup by drm driver. And leave it as a param for drm_pci_alloc() would cause confusion or mistake would corrupt the correct dma mask setting, as seen on intel hw which set wrong dma mask for hw status page. So remove it from drm_pci_alloc() function. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

The MMU code uses the copy_*_user_page() variants in access_process_vm() rather than copy_*_user() as the former includes an icache flush. This is important when doing things like setting software breakpoints with gdb. So switch the NOMMU code over to do the same. This patch makes the reasonable assumption that copy_from_user_page() won't fail - which is probably fine, as we've checked the VMA from which we're copying is usable, and the copy is not allowed to cross VMAs. The one case where it might go wrong is if the VMA is a device rather than RAM, and that device returns an error which - in which case rubbish will be returned rather than EIO.

Mike Frysinger authored
When working with FDPIC, there are many shared mappings of read-only code regions between applications (the C library, applet packages like busybox, etc.), but the current do_mmap_pgoff() function will issue an icache flush whenever a VMA is added to an MM instead of only doing it when the map is initially created. The flush can instead be done when a region is first mmapped PROT_EXEC. Note that we may not rely on the first mapping of a region being executable - it's possible for it to be PROT_READ only, so we have to remember whether we've flushed the region or not, and then flush the entire region when a bit of it is made executable. However, this also affects the brk area. That will no longer be executable. We can mprotect() it to PROT_EXEC on MPU-mode kernels, but for NOMMU mode kernels, when it increases the brk allocation, making sys_brk() flush the extra from the icache should suffice. The brk area probably isn't used by NOMMU programs since the brk area can only use up the leavings from the stack allocation, where the stack allocation is larger than requested.

The current code will load the stack size and protection markings, but then only use the markings in the MMU code path. The NOMMU code path always passes PROT_EXEC to the mmap() call. While this doesn't matter to most people whilst the code is running, it will cause a pointless icache flush when starting every FDPIC application. Typically this icache flush will be of a region on the order of 128KB in size, or may be the entire icache, depending on the facilities available on the CPU. In the case where the arch default behaviour seems to be desired (EXSTACK_DEFAULT), we probe VM_STACK_FLAGS for VM_EXEC to determine whether we should be setting PROT_EXEC or not. For arches that support an MPU (Memory Protection Unit - an MMU without the virtual mapping capability), setting PROT_EXEC or not will make an important difference. It should be noted that this change also affects the executability of the brk region, since ELF-FDPIC has that share with the stack. However, this is probably irrelevant as NOMMU programs aren't likely to use the brk region, preferring instead allocation via mmap().

Xiaotian Feng authored
There're some warnings of "nfsd: peername failed (err 107)!" socket error -107 means Transport endpoint is not connected. This warning message was outputed by svc_tcp_accept() [net/sunrpc/svcsock.c], when kernel_getpeername returns -107. This means socket might be CLOSED. And svc_tcp_accept was called by svc_recv() [net/sunrpc/svc_xprt.c] if (test_bit(XPT_LISTENER, &xprt->xpt_flags)) { <snip> newxpt = xprt->xpt_ops->xpo_accept(xprt); <snip> So this might happen when xprt->xpt_flags has both XPT_LISTENER and XPT_CLOSE. Let's take a look at commit b0401d72, this commit has moved the close processing after do recvfrom method, but this commit also introduces this warnings, if the xpt_flags has both XPT_LISTENER and XPT_CLOSED, we should close it, not accpet then close.

For some clocks, the old Ironlake DPLL calculator wold give m/n/p combinations that didn't match the spreadsheet of what HW validation tests. Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

This code generally fails to adjust the render clock, and when it does, it conflicts with some other register settings and can cause problems. So remove this code altogether. I'm reworking it now to do the right thing, but the only bit it will share is the VBT check for whether reclocking is supported, so I'm leaving that bit. Reverts most of 652c393a ("add dynamic clock frequency control"), though for many the regressions showed up in the later 181a5336 ("Fix render reclock availability detection").

This patch adds a new execbuf ioctl, execbuf2, for use by clients that want to control fence register allocation more finely. The buffer passed in to the new ioctl includes a new relocation type to indicate whether a given object needs a fence register assigned for the command buffer in question. Compatibility with the existing execbuf ioctl is implemented in terms of the new code, preserving the assumption that fence registers are required for pre-965 rendering commands.

There is nothing special to be done for interrupts which can wakeup the device from sleep on CP-INTC, but not having a set_wake implemented prevents use of common drivers which expect this function to be implemented for all wakeup interrupt sources. This patch fixes the issue encountered when using the omap-rtc driver on DA850. On DA850 the RTC alarm interrupt is used to wake up the SoC from deep sleep mode. Without this patch, the disable_irq_wake throws an unbalanced wake disable warning while resuming because the previous enable call fails for lack of set_wake implementation.
