2010-01-11kmemcheck: make bitfield annotations truly no-ops when disabledVegard Nossum
It turns out that even zero-sized struct members (int foo[0];) will affect the struct layout, causing us in particular to lose 4 bytes in struct sock. This patch fixes the regression in CONFIG_KMEMCHECK=n case.

2010-01-08DRM / i915: Fix resume regression on MSI Wind U100 w/o KMSRafael J. Wysocki
Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), among other things, removed the .suspend and .resume pointers from the struct drm_driver object in i915_drv.c, which broke resume without KMS on my MSI Wind U100. Fix this by reverting that part of commit cbda12d77ea59. [ The DRM layer will not use the class-specific suspend/resume functions if the driver is marked MODESET-aware, and conversely it will not register the PCI device if the drievr isn't so marked, so you always end up with _either_ the drm-class suspend/resume _or_ the PCI layer PM functionality, never both. - Linus ] Signed-off-by: Rafael J.

__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).

2010-01-07ARM: S3C64XX: Fix possible clock look in EPLL and MPLL clock chainsBen Dooks
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>

2010-01-06NOMMU: Use copy_*_user_page() in access_process_vm()Jie Zhang
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.

2010-01-06NOMMU: Avoiding duplicate icache flushes of shared mapsMike Frysinger
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.

2010-01-06FDPIC: Respect PT_GNU_STACK exec protection markings when creating NOMMU stackMike Frysinger
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.

2010-01-06nfsd: make sure data is on disk before calling ->fsyncChristoph Hellwig
nfsd is not using vfs_fsync, so I missed it when changing the calling convention during the 2.6.32 window. This patch fixes it to not only start the data writeout, but also wait for it to complete before calling into ->fsync.
