2010-09-13kprobes: Fix Kconfig dependencyMasami Hiramatsu1-2/+2
Fix Kconfig dependency among Kprobes, optprobe and kallsyms. Kprobes uses kallsyms_lookup for finding target function and checking instruction boundary, thus CONFIG_KPROBES should select CONFIG_KALLSYMS. Optprobe is an optional feature which is supported on x86 arch, and it also uses kallsyms_lookup for checking instructions in the target function. Since KALLSYMS_ALL just adds symbols of kernel variables, it doesn't need to select KALLSYMS_ALL.

2010-09-13drm/radeon/kms: fix the colorbuffer CS checker for r300-r500Marek Olšák1-5/+6
This commit fixes bogus CS rejection if it contains a sequence of the following operations: - Set the color buffer 0. track->cb[i].robj becomes non-NULL. - Render. - Set a larger zbuffer than the previously-set color buffer. - Set a larger scissor area as well. - Set the color channel mask to 0 to do depth-only rendering. - Render. --> rejected, because track->cb[i].robj remained non-NULL, therefore the conditional checking for the color channel mask and friends is not performed, and the larger scissor area causes the rejection. This fixes bugs: - https://bugs.freedesktop.org/show_bug.cgi?id=29762 - https://bugs.freedesktop.org/show_bug.cgi?id=28869 And maybe some others which seem to look the same.

2010-09-13drm/radeon/kms: increase lockup detection interval to 10 sec for r100-r500Marek Olšák1-12/+1
One subtest of mesa/demos/gltestperf takes 9 seconds to complete, so to prevent an unnecessary gpu reset followed by a hardlock, I am increasing the interval to 10 seconds after which a GPU is considered in a locked-up state. This is on RV530. However, with a little slower GPU, we would surpass the interval easily, so this is not a good fix for gltestperf. Nevertheless, this commit also fixes hardlocks in the applications which render at speed of less than 1 frame per second, where the whole frame consists of only one command stream. The game Tiny & Big is an example. This bar is now lowered to 0.1 fps. Now the question comes down to whether we should (often unsuccessfully) reset the GPU at all? Once we have stable enough drivers, we won't have to. Has the time come already? If possible, this commit should go to stable as well.

Fix a bug introduced with commit de725de and the change in the meaning of the return value of intel_pmu_handle_irq(). With the current code, when you are using the BTS, you get 'dazed by NMI' each time the BTS buffer fills up. BTS does interrupt on the PMU vector, thus NMI.

The NFSv4 client's callback server calls svc_gss_principal(), which is defined in the auth_rpcgss.ko The NFSv4 server has the same dependency, and in addition calls svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(), gss_pseudoflavor_to_service() and gss_mech_put() from the same module.

2010-09-12statfs() gives ESTALE errorMenyhart Zoltan1-0/+8
Hi, An NFS client executes a statfs("file", &buff) call. "file" exists / existed, the client has read / written it, but it has already closed it. user_path(pathname, &path) looks up "file" successfully in the directory-cache and restarts the aging timer of the directory-entry. Even if "file" has already been removed from the server, because the lookupcache=positive option I use, keeps the entries valid for a while. nfs_statfs() returns ESTALE if "file" has already been removed from the server. If the user application repeats the statfs("file", &buff) call, we are stuck: "file" remains young forever in the directory-cache.
