Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts

2012-09-12T02:37:14Z

commit 67a806d9499353fabd5b5ff07337f3aa88a1c3ba upstream. The following build error occurred during an alpha build: net/core/sock.c:274:36: error: initializer element is not constant Dave Anglin says: > Here is the line in sock.i: > > struct static_key memalloc_socks = ((struct static_key) { .enabled = > ((atomic_t) { (0) }) }); The above line contains two compound literals. It also uses a designated initializer to initialize the field enabled. A compound literal is not a constant expression. The location of the above statement isn't fully clear, but if a compound literal occurs outside the body of a function, the initializer list must consist of constant expressions.

alpha: Don't export SOCK_NONBLOCK to user space.

2012-09-12T02:37:14Z

commit a2fa3ccd7b43665fe14cb562761a6c3d26a1d13f upstream. Currently we export SOCK_NONBLOCK to user space but that conflicts with the definition from glibc leading to compilation errors in user programs (e.g. see Debian bug #658460). The generic socket.h restricts the definition of SOCK_NONBLOCK to the kernel, as does the MIPS specific socket.h, so let's do the same on Alpha.

alpha: fix 32/64-bit bug in futex support

2012-03-12T19:31:25Z

commit 62aca403657fe30e5235c5331e9871e676d9ea0a upstream. Michael Cree said: : : I have noticed some user space problems (pulseaudio crashes in pthread : : code, glibc/nptl test suite failures, java compiler freezes on SMP alpha : : systems) that arise when using a 2.6.39 or later kernel on Alpha. : : Bisecting between 2.6.38 and 2.6.39 (using glibc/nptl test suite as : : criterion for good/bad kernel) eventually leads to: : : : : 8d7718aa082aaf30a0b4989e1f04858952f941bc is the first bad commit : : commit 8d7718aa082aaf30a0b4989e1f04858952f941bc : : Author: Michel Lespinasse : : Date: Thu Mar 10 18:50:58 2011 -0800 : : : : futex: Sanitize futex ops argument types : : : : Change futex_atomic_op_inuser and futex_atomic_cmpxchg_inatomic : : prototypes to use u32 types for the futex as this is the data type the : : futex core code uses all over the place. : : : : Looking at the commit I see there is a change of the uaddr argument in : : the Alpha architecture specific code for futexes from int to u32, but I : : don't see why this should cause a problem. Richard Henderson said: : futex_atomic_cmpxchg_inatomic(u32 *uval, u32 __user *uaddr, : u32 oldval, u32 newval) : ... : : "r"(uaddr), "r"((long)oldval), "r"(newval) : : : There is no 32-bit compare instruction. These are implemented by : consistently extending the values to a 64-bit type. Since the : load instruction sign-extends, we want to sign-extend the other : quantity as well (despite the fact it's logically unsigned). : : So: : : - : "r"(uaddr), "r"((long)oldval), "r"(newval) : + : "r"(uaddr), "r"((long)(int)oldval), "r"(newval) : : should do the trick. Michael said: : This fixes the glibc test suite failures and the pulseaudio related : crashes, but it does not fix the java compiiler lockups that I was (and : are still) observing. That is some other problem.
