2011-11-17KVM: s390: Fix tprot lockingChristian Borntraeger
There is a potential host deadlock in the tprot intercept handling. We must not hold the mmap semaphore while resolving the guest address. If userspace is remapping, then the memory detection in the guest is broken anyway so we can safely separate the address translation from walking the vmas.

2011-11-17KVM: s390: Fix RUNNING flag misinterpretationCornelia Huck
CPUSTAT_RUNNING was implemented signifying that a vcpu is not stopped. This is not, however, what the architecture says: RUNNING should be set when the host is acting on the behalf of the guest operating system. CPUSTAT_RUNNING has been changed to be set in kvm_arch_vcpu_load() and to be unset in kvm_arch_vcpu_put(). For signifying stopped state of a vcpu, a host-controlled bit has been used and is set/unset basically on the reverse as the old CPUSTAT_RUNNING bit (including pushing it down into stop handling proper in handle_stop()).

2011-11-17writeback: hard throttle 1000+ dd on a slow USB stickWu Fengguang
The sleep based balance_dirty_pages() can pause at most MAX_PAUSE=200ms on every 1 4KB-page, which means it cannot throttle a task under 4KB/200ms=20KB/s. So when there are more than 512 dd writing to a 10MB/s USB stick, its bdi dirty pages could grow out of control. Even if we can increase MAX_PAUSE, the minimal (task_ratelimit = 1) means a limit of 4KB/s. They can eventually be safeguarded by the global limit check (nr_dirty < dirty_thresh). However if someone is also writing to an HDD at the same time, it'll get poor HDD write performance. We at least want to maintain good write performance for other devices when one device is attacked by some "massive parallel" workload, or suffers from slow write bandwidth, or somehow get stalled due to some error condition (eg. NFS server not responding). For a stalled device, we need to completely block its dirtiers, too, before its bdi dirty pages grow all the way up to the global limit and leave no space for the other functional devices. So change the loop exit condition to /* * Always enforce global dirty limit; also enforce bdi dirty limit * if the normal max_pause sleeps cannot keep things under control. */ if (nr_dirty < dirty_thresh && (bdi_dirty < bdi_thresh || bdi->dirty_ratelimit > 1)) break; which can be further simplified to if (task_ratelimit) break; Signed-off-by: Wu Fengguang <fengguang.wu@intel.com>

2011-11-17stmmac: parameters auto-tuning through HW cap regGiuseppe CAVALLARO
New GMAC devices (newer than the databook 3.50a) have the HW capability register that provides which features are actually supported by the hardware. On old devices many information have to be passed through the platform, for example: enhanced descriptor structure, TX COE etc. These are mandatory to properly configure the driver. This remains still valid because the driver has to support old Synopsys devices but now it's also able to override them using the values from the HW capability register if supported.

2011-11-17powerpc/signal32: Fix sigset_t conversion when copying to userWill Deacon
On PPC64, put_sigset_t converts a sigset_t to a compat_sigset_t before copying it to userspace. There is a typo in the case that we have 4 words to copy, meaning that we corrupt the compat_sigset_t. It appears that _NSIG_WORDS can't be greater than 2 at the moment so this code is probably always optimised away anyway.

2011-11-17powerpc: Fix atomic_xxx_return barrier semanticsBenjamin Herrenschmidt
The Documentation/memory-barriers.txt document requires that atomic operations that return a value act as a memory barrier both before and after the actual atomic operation. Our current implementation doesn't guarantee this. More specifically, while a load following the isync can not be issued before stwcx. has completed, that completion doesn't architecturally means that the result of stwcx. is visible to other processors (or any previous stores for that matter) (typically, the other processors L1 caches can still hold the old value). This has caused an actual crash in RCU torture testing on Power 7 This fixes it by changing those atomic ops to use new macros instead of RELEASE/ACQUIRE barriers, called ATOMIC_ENTRY and ATMOIC_EXIT barriers, which are then defined respectively to lwsync and sync. I haven't had a chance to measure the performance impact (or rather what I measured with kernel compiles is in the noise, I yet have to find a more precise benchmark) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Paul E.

2011-11-17powerpc: Remove buggy 9-year-old test for binutils < 2.12.1Kyle Moffett
Recent binutils refuses to assemble AltiVec opcodes when in e500/SPE mode, as some of those opcodes alias the "SPE" instructions. This triggers an ancient binutils version check even when building a kernel with CONFIG_ALTIVEC disabled. In theory, the check could be conditionalized on CONFIG_ALTIVEC, but in practice it has long outlived its utility. It is virtually impossible to find binutils older than 2.12.1 (released 2002) in the wild anymore. Even ancient RedHat Enterprise Linux 4 has binutils-2.14. To fix the kernel build when done natively on e500 systems with this new binutils, the test is simply removed.

2011-11-17powerpc/book3e-64: Fix debug support for userspaceKumar Gala
With the introduction of CONFIG_PPC_ADV_DEBUG_REGS user space debug is broken on Book-E 64-bit parts that support delayed debug events. When switch_booke_debug_regs() sets DBCR0 we'll start getting debug events as MSR_DE is also set and we aren't able to handle debug events from kernel space. We can remove the hack that always enables MSR_DE and loads up DBCR0 and just utilize switch_booke_debug_regs() to get user space debug working again. We still need to handle critical/debug exception stacks & proper save/restore of state for those exception levles to support debug events from kernel space like we have on 32-bit.
