__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096 systems it hogs 16MB of memory. This is way too much for a quite probably unused facility (only KVM uses dynamic TR registers). Change to an array of pointers, and allocate entries as needed on a per cpu basis. Change the name too as the __per_cpu_ prefix is confusing (this isn't a classic <linux/percpu.h> type object).

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>

There is a possibility of a loop happening in the PLL output clock chain on the S3C64XX series. clk_mpll's parent was set to be clk_mout_mpll, but this is fed from clk_fout_epll (which is also clk_mpll). clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll and thus should be considered a seperate clock. Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

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.

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().

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.

With the recent irq migration fixes (post 2.6.32), Gary Hade has noticed "No IRQ handler for vector" messages during the 2.6.33-rc1 kernel boot on IBM AMD platforms and root caused the issue to this commit: > commit 23359a88 > Author: Suresh Siddha <suresh.b.siddha@intel.com> > Date: Mon Oct 26 14:24:33 2009 -0800 > > x86: Remove move_cleanup_count from irq_cfg As part of this patch, we have removed the move_cleanup_count check in smp_irq_move_cleanup_interrupt(). With this change, we can run into a situation where an irq cleanup interrupt on a cpu can cleanup the vector mappings associated with multiple irqs, of which one of the irq's migration might be still in progress. As such when that irq hits the old cpu, we get the "No IRQ handler" messages. Fix this by checking for the irq_cfg's move_in_progress and if the move is still in progress delay the vector cleanup to another irq cleanup interrupt request (which will happen when the irq starts arriving at the new cpu destination).

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.
