For the kernel, some good effects are to eliminate the hacky "VirtualAddress" typedef in favor of "unsigned long", to eliminate a bunch of spurious kernel doc comments, to remove the dead "bt_read_memory" function, and to use "__tilegx__" in #ifdefs instead of "TILE_CHIP".

} -- cgit v1.2.3 From df29ccb6c06dcb65867d4fd3c2fa473017f60ecc Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 2 May 2011 15:13:13 -0400 Subject: arch/tile: allow nonatomic stores to interoperate with fast atomic syscalls This semantic was already true for atomic operations within the kernel, and this change makes it true for the fast atomic syscalls (__NR_cmpxchg and __NR_atomic_update) as well. Previously, user-space had to use the fast atomic syscalls exclusively to update memory, since raw stores could lose a race with the atomic update code even when the atomic update hadn't actually modified the value. With this change, we no longer write back the value to memory if it hasn't changed. This allows certain types of idioms in user space to work as expected, e.g. "atomic exchange" to acquire a spinlock, followed by a raw store of zero to release the lock.

It also adds a number of missing interfaces that showed up as build failures when trying to build various drivers not normally included in the "tile" distribution: ioremap_wc(), memset_io(), io{read,write}{16,32}be(), virt_to_bus(), bus_to_virt(), irq_canonicalize(), __pte(), __pgd(), and __pmd(). I also added a cast in virt_to_page() since not all callers pass a pointer. I fixed to properly include a __KERNEL__ guard for the __ARCH_WANT_STAT64 symbol, and to use __builtin_bswap32() even for our 64-bit architecture, since the same code is produced. I added an export for get_cycles(), since it's used in some modules. And I made properly include the __KERNEL__ guard, even though it's not yet exported, since it likely will be soon.

Change inv_buffer() to just do an mf instead of any kind of fancier barrier, since you're obviously not going to be waiting for anything once the local homecache is invalidated. Fix tilepro.c network driver not to bother calling finv_buffer when stopping the EPP, but just mf after memset to ensure that it will not see any packet data after we finish stopping; use finv_buffer_remote() when doing exit-time cleanup. This also fixes a (not very interesting) generic Linux build failure where drivers/scsi/st.c declares its own flush_buffer().

This is unsafe even if the task can't run (I assume it is pinned to the same CPU), its parent can reap the task and set ->sighand = NULL right after this check. Even if the compiler dosn't read ->sighand twice and this memory can't to away __group_send_sig_info() is wrong after that. Use do_send_sig_info(). 2. Send SIGILL to the thread, not to the whole process. Unless it has the handler or blocked this kills the whole thread-group as before. IIUC, different threads can be bound to different rect's. 3. Check PF_EXITING instead of ->sighand. A zombie thread can go away but its ->sighand can be !NULL.
