use of explicit labels in inline asm is a Bad Idea(tm), since gcc can decide to inline the function in several places. Fixed by use of 1f/f: instead of .Lfitsin/.Lfitsin: Signed-off-by:

extern declaration followed by static in drivers/serial/m32r_sio.c Signed-off-by:

either icu_data declaration for SMP case should be taken out of m32102.h, or its declarations for m32700ut and opsput should not be static for SMP. Patch does the latter - judging by comments in m32102.h it is intended to be non-static. Signed-off-by:

extern on physid_2_cpu[] does not belong in smp.h - the thing is static. Signed-off-by:

"=m" (lock->lock) / "1" (lock->lock) makes gcc4 unhappy; fixed by s/1/m/, same as in case of i386 rwsem.h where such variant had been accepted by both Linus and rth. Signed-off-by:

alpha xchg has to be a macro - alpha disables always_inline and if that puppy does not get inlined, we immediately blow up on undefined reference. Happens even on gcc3; with gcc4 that happens a _lot_. Signed-off-by:

on UP smp_call_function() is expanded to expression. Alpha oprofile calls that puppy and ignores the return value. And has -Werror for arch/*... Signed-off-by:

since sparc32 Kconfig includes drivers/char/Kconfig (instead of duplicating its parts) we need several new dependencies there to exclude the stuff broken on sparc32 and not excluded by existing dependencies. Signed-off-by:

CONFIG_PM is broken on 44x; removed duplicate entry for CONFIG_PM, made the inclusion of generic one conditional on BROKEN || !44x. Signed-off-by:

a bunch of ppc 4xx variants unconditionally calls early_serial_setup() and therefore needs SERIAL_8250 Signed-off-by:

ppc SMP is supported only for 6xx/POWER3/POWER4 - i.e. ones that have PPC_STD_MMU. Dependency fixed. Signed-off-by:

parport_pc shouldn't be picked on m32r (no asm/parport.h, for starters) Signed-off-by:

airo_cs is broken on m32r; marked as such. [Proper fix would involve separating PCI-dependent parts and making sure they don't get in the way _and_ arranging for asm/scatterlist.h getting picked on m32r] Signed-off-by:

ISA parts of tms380tr are using ISA DMA helpers and should depend on ISA_DMA_API. Signed-off-by:

arv uses constants provided only by include/asm-m32r/m32700ut/m32700ut_lan.h It won't build for any subarchitecture other than M32700UT; marked as such. Signed-off-by:

infiniband uses PCI helpers all over the place (including the core parts) and won't build without PCI. Signed-off-by:

DEBUG_PAGEALLOC is broken on m32r - the option had been blindly copied from i386; kernel_map_pages() had not and that's what is needed for DEBUG_PAGEALLOC to work (or link, while we are at it). Signed-off-by:

genrtc is not for m32r; marked as such. Probably ought to put that into arch/* - list of "don't build it on <platform>" is getting too long. Signed-off-by:

We weren't actually waking up the md thread after setting MD_RECOVERY_NEEDED when assembling an array, so it is possible to lose a race and not actually start resync. So add a call to md_wakeup_thread, and while we are at it, remove all the "if (mddev->thread)" guards as md_wake_thread does its own checking. Signed-off-by:

With CONFIG_PREEMPT && !CONFIG_SMP, it's possible for sys_getppid to return a bogus value if the parent's task_struct gets reallocated after current->group_leader->real_parent is read: asmlinkage long sys_getppid(void) { int pid; struct task_struct *me = current; struct task_struct *parent; parent = me->group_leader->real_parent; RACE HERE => for (;;) { pid = parent->tgid; #ifdef CONFIG_SMP { struct task_struct *old = parent; /* * Make sure we read the pid before re-reading the * parent pointer: */ smp_rmb(); parent = me->group_leader->real_parent; if (old != parent) continue; } #endif break; } return pid; } If the process gets preempted at the indicated point, the parent process can go ahead and call exit() and then get wait()'d on to reap its task_struct. When the preempted process gets resumed, it will not do any further checks of the parent pointer on !CONFIG_SMP: it will read the bad pid and return. So, the same algorithm used when SMP is enabled should be used when preempt is enabled, which will recheck ->real_parent in this case.

Intention of this bit is to force pushing of the existing send queue when TCP_CORK or TCP_NODELAY state changes via setsockopt(). But it's easy to create a situation where the bit never clears. For example, if the send queue starts empty: 1) set TCP_NODELAY 2) clear TCP_NODELAY 3) set TCP_CORK 4) do small write() The current code will leave TCP_NAGLE_PUSH set after that sequence. Unconditionally clearing the bit when new data is added via skb_entail() solves the problem. Signed-off-by:
