alpha: makefile: don't enforce small data model for kernel builds

2013-08-20T15:26:28Z

commit cd8d2331756751b6aeb855a3c9cb0a92fbd9c725 upstream. Due to all of the goodness being packed into today's kernels, the resulting image isn't as slim as it once was. In light of this, don't pass -msmall-data to gcc, which otherwise results in link failures due to impossible relocations when compiling anything but the most trivial configurations.

alpha: Add missing RCU idle APIs on idle loop

2012-10-12T20:38:54Z

commit 4c94cada48f7c660eca582be6032427a5e367117 upstream. In the old times, the whole idle task was considered as an RCU quiescent state. But as RCU became more and more successful overtime, some RCU read side critical section have been added even in the code of some architectures idle tasks, for tracing for example. So nowadays, rcu_idle_enter() and rcu_idle_exit() must be called by the architecture to tell RCU about the part in the idle loop that doesn't make use of rcu read side critical sections, typically the part that puts the CPU in low power mode. This is necessary for RCU to find the quiescent states in idle in order to complete grace periods. Add this missing pair of calls in the Alpha's idle loop. Reported-by: Paul E.

Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts

2012-10-02T17:29:55Z

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.

2012-09-14T17:00:06Z

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 fpu.h usage in userspace

2012-09-14T17:00:06Z

commit 0be421862b857e61964435ffcaa7499cf77a5e5a upstream. After commit ec2212088c42 ("Disintegrate asm/system.h for Alpha"), the fpu.h header which we install for userland started depending on special_insns.h which is not installed. However, fpu.h only uses that for __KERNEL__ code, so protect the inclusion the same way to avoid build breakage in glibc: /usr/include/asm/fpu.h:4:31: fatal error: asm/special_insns.h: No such file or directory Reported-by: Matt Turner Signed-off-by: Mike Frysinger Signed-off-by: Michael Cree Acked-by: Matt Turner Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

arch/alpha/kernel/console.c:locate_and_init_vga uses vga_con, causing build failures if VGA_CONSOLE was not set and MARVEL, TITAN, DP264, or GENERIC alpha system types were set. Reported-by: Raúl Porcel Signed-off-by: Matt Turner
