Here are three more sparse-triggered fixes which didn't fit anywhere else. The first one gets rid of some quoting in palinfo.c which sparse doesn't like. This used to be necessary because GCC would otherwise warn about an unknown trigraph. That's not a problem anymore since the kernel is now being compiled with -Wno-trigraphs. The efirtc.c patch is mostly sparse-annotations but also cleans up trailing whitespace. Finally, the bitfields in rwlock_t are changed to be explicitly "unsigned" to avoid a warning from sparse (it doesn't like 1-bit signed bitfields in particular).

This patch adds __iomem annotations. The only less-than-trivial part of the patch is the change of ipi_base_addr from "unsigned long" to "void __iomem *" but even that part should be safe. The patch results in additional warnings from certain drivers (e.g., eepro100.c) but the warnings are harmless and just indicate that the offending drivers need to be updated for the more strict __iomem checking. The patch has been boot-tested. Signed-off-by: David Mosberger-Tang <davidm@hpl.hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

This enables sparse for ia64 and adds a basic set of __user annotations. Apart for sys_execve() and the uaccess.h changes, the patch is trivially safe. Also note that in gcc_intrin.h, I changed "asm __volatile" to "asm volatile" since sparse didn't like the old version (and it's a "strane" version anyhow). Patch has been (boot) tested.

Sparse really wants NULL for NULL-pointers. This patch makes it so. The patch should be safe. It compiles fine, creates no additional warnings, and the results has been boot-tested on an rx2600. Signed-off-by: David Mosberger-Tang <davidm@hpl.hp.com> Signed-off-by: Tony Luck <tomy.luck@intel.com>

copy_siginfo_from_user32() directly dereferences a user-pointer, which is a no-no. At that point, to->si_code already has been initialized so I think we can just use to->si_code instead. Compile-tested (only) patch attached. Signed-off-by: davidm@hpl.hp.com Signed-off-by: Tony Luck <tony.luck@intel.com>

Here is another fix for a sparse-detected bug: turns out ptrace_getregs() and ptrace_putregs() did unchecked user-memory accesses! These were tricky to see, so it's not surprising that they went unnoticed so far. Fortunately, sparse can detect these trivially. Patch below should fix the problem, but it's completely untested (I don't have any testcases for getregs/putregs). These were found by sparse.

the pfm_fasync() function must not lock the context and mask interrupts because the fasync_helper() function may allocate memory and this could lead to sleeping, due to SLAB_KERNEL memory type, if no memory is available. Going to sleep with interrupts mask is not allowed otherwise you have a deadlock. The locking of the context is not necessary in this function because it is protected by caller via get_fd()/put_fd(). The async_queue is also protected. Serialization to pfm_fasync() is also ensured by caller. The fix is to drop the PROTECT_CTX() and UNPROTECT_CTX() calls. signed-off-by: stephane eranian <eranian@hpl.hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

We really need to check that we have access to the whole of the signal frame when we allocate it, rather than "most of it" when we have iWMMXt extensions selected.

Ulrich Drepper points out that EPOLL_CTL_DEL doesn't need to copy any of the hash events. Also, we should specify in the man pages that a NULL is allowed in EPOLL_CTL_DEL. Currently it does not say that. Also, starting from when epoll uses rbtrees instead of hashes, the 'size' hint passed to epoll_create(2) is no more used. But since an API change has clearly to be excluded, I guess it'll stay as is. Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
