2006-12-08[PATCH] UML: add generic BUG supportJeff Dike
The BUG changes in -mm3 need some arch support. This patch adds the UML support needed. For the most part, it was stolen from the underlying architecture.

2006-12-08[PATCH] Generic BUG for x86-64Jeremy Fitzhardinge
This makes x86-64 use the generic BUG machinery. The main advantage in using the generic BUG machinery for x86-64 is that the inlined overhead of BUG is just the ud2a instruction; the file+line information are no longer inlined into the instruction stream. This reduces cache pollution.

2006-12-08[PATCH] Generic BUG for i386Jeremy Fitzhardinge
This makes i386 use the generic BUG machinery. There are no functional changes from the old i386 implementation. The main advantage in using the generic BUG machinery for i386 is that the inlined overhead of BUG is just the ud2a instruction; the file+line(+function) information are no longer inlined into the instruction stream. This reduces cache pollution, and makes disassembly work properly.

2006-12-08[PATCH] tty: ->signal->tty lockingPeter Zijlstra
Fix the locking of signal->tty. Use ->sighand->siglock to protect ->signal->tty; this lock is already used by most other members of ->signal/->sighand. And unless we are 'current' or the tasklist_lock is held we need ->siglock to access ->signal anyway. (NOTE: sys_unshare() is broken wrt ->sighand locking rules) Note that tty_mutex is held over tty destruction, so while holding tty_mutex any tty pointer remains valid. Otherwise the lifetime of ttys are governed by their open file handles. This leaves some holes for tty access from signal->tty (or any other non file related tty access). It solves the tty SLAB scribbles we were seeing. (NOTE: the change from group_send_sig_info to __group_send_sig_info needs to be examined by someone familiar with the security framework, I think it is safe given the SEND_SIG_PRIV from other __group_send_sig_info invocations) [schwidefsky@de.ibm.com: 3270 fix] [akpm@osdl.org: various post-viro fixes] Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Alan Cox <alan@redhat.com> Cc: Oleg Nesterov <oleg@tv-sign.ru> Cc: Prarit Bhargava <prarit@redhat.com> Cc: Chris Wright <chrisw@sous-sol.org> Cc: Roland McGrath <roland@redhat.com> Cc: Stephen Smalley <sds@tycho.nsa.gov> Cc: James Morris <jmorris@namei.org> Cc: "David S.

Don't mask the lower 12-bit of the page fault address. In the current m32r kernel implementation, we use an access exception to detect page faults. This patch fixes ace_handler (access exception handler) for m32r. In order to check userspace address in do_page_fault, we have to pass full 32-bit address to do_page_fault.

2006-12-08[PATCH] m32r: make userspace headers platform-independentHirokazu Takata
The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa configuration" for userspace application programs, such as glibc, gdb, etc. This is because the recent kernel do not include linux/config.h not to expose kernel headers for userspace. To fix the above compile errors, this patch fixes two headers ptrace.h and sigcontext.h for m32r and makes them platform-independent.

2006-12-07[ARM] 3983/2: remove unused argument to __bug()Nicolas Pitre
It appears that include/asm-arm/bug.h requires include/linux/stddef.h for the definition of NULL. It seems that stddef.h was always included indirectly in most cases, and that issue was properly fixed a while ago. Then commit 5047f09b56d0bc3c21aec9cb16de60283da645c6 incorrectly reverted change from commit ff10952a547dad934d9ed9afc5cf579ed1ccb53a (bad dwmw2) and the problem recently resurfaced. Because the third argument to __bug() is never used anyway, RMK suggested getting rid of it entirely instead of readding #include <linux/stddef.h> which this patch does.

2006-12-07[IA64] tidy up return value of ip_fast_csumChen, Kenneth W
While working on implementing csum_ipv6_magic, I noticed that current version of ip_fast_csum will potentially return bits above "unsigned short" as 1. While no harm is done right now because all call sites will chop off the upper bits when it uses the return value. However, this is still dangerous and buggy. Here is a patch to enforce that the function really returns unsigned short in the native register format. The fix is free as there are plenty open slot to add one more asm instruction.

2006-12-07[PATCH] add rtc-omap driverDavid Brownell
This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

2006-12-07[PATCH] hotplug CPU: clean up hotcpu_notifier() useIngo Molnar
There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn, prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus generating compiler warnings of unused symbols, hence forcing people to add #ifdefs. the compiler can skip truly unused functions just fine: text data bss dec hex filename 1624412 728710 3674856 6027978 5bfaca vmlinux.before 1624412 728710 3674856 6027978 5bfaca vmlinux.after [akpm@osdl.org: topology.c fix] Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-12-07[PATCH] smp_call_function_single() check that local interrupts are enabledAndrew Morton
smp_call_function_single() can deadlock if the caller disabled local interrupts (the target CPU could be spinning on call_lock). Check for that. Why on earth do these functions use spin_lock_bh()??

2006-12-07[PATCH] kprobes: enable booster on the preemptible kernelMasami Hiramatsu
When we are unregistering a kprobe-booster, we can't release its instruction buffer immediately on the preemptive kernel, because some processes might be preempted on the buffer. The freeze_processes() and thaw_processes() functions can clean most of processes up from the buffer. There are still some non-frozen threads who have the PF_NOFREEZE flag. If those threads are sleeping (not preempted) at the known place outside the buffer, we can ensure safety of freeing. However, the processing of this check routine takes a long time. So, this patch introduces the garbage collection mechanism of insn_slot. It also introduces the "dirty" flag to free_insn_slot because of efficiency. The "clean" instruction slots (dirty flag is cleared) are released immediately. But the "dirty" slots which are used by boosted kprobes, are marked as garbages. collect_garbage_slots() will be invoked to release "dirty" slots if there are more than INSNS_PER_PAGE garbage slots or if there are no unused slots.
