2010-08-03kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command lineSam Ravnborg1-2/+2
It is now possible to assign options to AS and CC on the command line - which is only used for built-in code. {A,C}FLAGS_KERNEL was used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC without overriding the original value. Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL that is used by arch specific files and free up {A,C}FLAGS_KERNEL so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated.

It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

2010-08-01KVM: ia64: cleanup kvm_ia64_sync_dirty_log()Takuya Yoshikawa1-19/+11
kvm_ia64_sync_dirty_log() is a helper function for kvm_vm_ioctl_get_dirty_log() which copies ia64's arch specific dirty bitmap to general one in memslot. So doing sanity checks in this function is unnatural. We move these checks outside of this and change the prototype appropriately.

2010-07-30PCI: MSI: Restore read_msi_msg_desc(); add get_cached_msi_msg_desc()Ben Hutchings2-2/+2
commit 2ca1af9aa3285c6a5f103ed31ad09f7399fc65d7 "PCI: MSI: Remove unsafe and unnecessary hardware access" changed read_msi_msg_desc() to return the last MSI message written instead of reading it from the device, since it may be called while the device is in a reduced power state. However, the pSeries platform code really does need to read messages from the device, since they are initially written by firmware. Therefore: - Restore the previous behaviour of read_msi_msg_desc() - Add new functions get_cached_msi_msg{,_desc}() which return the last MSI message written - Use the new functions where appropriate Acked-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-07-27[IA64] increase ia64 static per cpu areaTony Luck1-1/+1
I've been trying to avoid this for a long time ... but per-cpu space has slowly been growing. Tejun has some patches in linux-next that pre-reserve some space (PERCPU_DYNAMIC_EARLY_SIZE) for use before slab comes online ... and this pushes ia64 above the 64K current limit on static percpu space. I could probably squeeze it back under (we are only over by 512 bytes). But I don't think that I'll be able to squeeze it down enough to build a comfortable breathing space - and I don't want to keep nibbling off a dozen bytes here and there every time some generic code bumps us back over the limit. Next available supported page size is 256K ... so we have to quadruple the available space - a bigger jump than I'd like. But perhaps it will be enough to last a few more years before it needs to be increased again. Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
2010-07-27timkeeping: Fix update_vsyscall to provide wall_to_monotonic offsetJohn Stultz1-3/+4
update_vsyscall() did not provide the wall_to_monotoinc offset, so arch specific implementations tend to reference wall_to_monotonic directly. This limits future cleanups in the timekeeping core, so this patch fixes the update_vsyscall interface to provide wall_to_monotonic, allowing wall_to_monotonic to be made static as planned in Documentation/feature-removal-schedule.txt Signed-off-by: John Stultz <johnstul@us.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Anton Blanchard <anton@samba.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Tony Luck <tony.luck@intel.com> LKML-Reference: <1279068988-21864-7-git-send-email-johnstul@us.ibm.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Typo in down_spin() meant it only read the low 32 bits of the "serve" value, instead of the full 64 bits. This results in the system hanging when the values in ticket/serve get larger than 32-bits. A big enough system running the right test can hit this in a just a few hours.

Define WQ_MAX_ACTIVE and create keventd with max_active set to half of it which means that keventd now can process upto WQ_MAX_ACTIVE / 2 - 1 works concurrently. Unless some combination can result in dependency loop longer than max_active, deadlock won't happen and thus it's unnecessary to check whether current_is_keventd() before trying to schedule a work.

2010-05-27asm-generic: remove ARCH_HAS_SG_CHAIN in scatterlist.hFUJITA Tomonori1-2/+2
There are more architectures that don't support ARCH_HAS_SG_CHAIN than those that support it. This removes removes ARCH_HAS_SG_CHAIN in asm-generic/scatterlist.h and lets arhictectures to define it. It's clearer than defining ARCH_HAS_SG_CHAIN asm-generic/scatterlist.h and undefing it in arhictectures that don't support it.

2010-05-27asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()FUJITA Tomonori1-0/+3
There are only two ways to define sg_dma_len(); use sg->dma_length or sg->length. This patch introduces NEED_SG_DMA_LENGTH that enables architectures to choose sg->dma_length or sg->length.

2010-05-27ia64: remove unnecessary sync_single_range_* in swiotlb_dma_opsFUJITA Tomonori1-2/+0
sync_single_range_for_cpu and sync_single_range_for_device hooks in swiotlb_dma_ops are unnecessary because sync_single_for_cpu and sync_single_for_device are used there.

2010-05-27ia64: ptrace_attach_sync_user_rbs: avoid "task->signal != NULL" checksOleg Nesterov1-2/+2
Preparation to make task->signal immutable, no functional changes. It doesn't matter which pointer we check under tasklist to ensure the task was not released, ->signal or ->sighand. But we are going to make ->signal refcountable, change the code to use ->sighand. Note: this code doesn't need this check and tasklist_lock at all, it should be converted to use lock_task_sighand(). And, the code under SIGNAL_STOP_STOPPED check looks wrong.
