It really is needed for UP builds and there doesn't seem to be an easy way to avoid include-hell otherwise. Signed-off-by: davidm@hpl.hp.com Signed-off-by: Tony Luck (04/10/06 1.2060) [IA64] Don't hardcode offsets in thread_info We had hardcoded defines for TI_TASK TI_EXEC_DOMAIN, TI_FLAGS, TI_CPU, TI_ADDR_LIMIT, TI_PRE_COUNT, TI_RESTART_BLOCK; but only two of these were ever used. Remove all from thread_info.h, and generate the two that we do use (TI_FLAGS and TI_PRE_COUNT) in asm_offsets.c Patch supplied by Zou Nan hai Signed-off-by: Tony Luck (04/10/05 1.2059) [IA64] minor sparse cleanups 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). Signed-off-by: David Mosberger-Tang Signed-off-by: Tony Luck (04/10/05 1.2058) [IA64] sparse __iomem annotations 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 Signed-off-by: Tony Luck (04/10/05 1.2057) [IA64] minimal sparse-enablement; add __user annotations 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. Signed-off-by: David Mosberger-Tang Signed-off-by: Tony Luck (04/10/05 1.2056) [IA64] sparse "long" constant cleanup patch Sparse wants us to be clear about (unsigned) long constants. Make it so. Signed-off-by: David Mosberger-Tang Signed-off-by: Tony Luck (04/10/05 1.2055) [IA64] sparse 0 vs. NULL cleanup patch 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 Signed-off-by: Tony Luck (04/10/05 1.2054) [IA64] Don't directly deref user pointers. 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 (04/10/05 1.2052) [IA64] ptrace.c: Fix unchecked user-memory accesses due to ptrace_{get,set}regs() 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.

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 Signed-off-by: Tony Luck (04/10/01 1.2009.3.4) [IA64] Makefile: Fix to make ccache/distcc happy. the (tested) patch below fixes ccache/distcc-assisted building of the ia64 tree. (CC is "ccache distcc gcc" in that case, not a simple one-word "gcc" - this confused the check-gas and toolchain-flags scripts.) Signed-off-by: Ingo Molnar Signed-off-by: Tony Luck
