Looking into the active_asids array is not enough, as we also need to look into the reserved_asids array (they both represent processes that are currently running). Also, not holding the ASID allocator lock is racy, as another CPU could schedule that process and trigger a rollover, making the erratum workaround miss an IPI. Exposing this outside of context.c is a little ugly on the side, so let's define a new entry point that the erratum workaround can call to obtain the cpumask.

On a CPU that never ran anything, both the active and reserved ASID fields are set to zero. In this case the ASID_TO_IDX() macro will return -1, which is not a very useful value to index a bitmap. Instead of trying to offset the ASID so that ASID #1 is actually bit 0 in the asid_map bitmap, just always ignore bit 0 and start the search from bit 1. This makes the code a bit more readable, and without risk of OoB access. Cc: <stable@vger.kernel.org> # 3.9 Acked-by:

When a CPU is running a process, the ASID for that process is held in a per-CPU variable (the "active ASIDs" array). When the ASID allocator handles a rollover, it copies the active ASIDs into a "reserved ASIDs" array to ensure that a process currently running on another CPU will continue to run unaffected. The active array is zero-ed to indicate that a rollover occurred. Because of this mechanism, a reserved ASID is only remembered for a single rollover. A subsequent rollover will completely refill the reserved ASIDs array. In a severely oversubscribed environment where a CPU can be prevented from running for extended periods of time (think virtual machines), the above has a horrible side effect: [P{a} denotes process P running with ASID a] CPU-0 CPU-1 A{x} [active = <x 0>] [suspended] runs B{y} [active = <x y>] [rollover: active = <0 0> reserved = <x y>] runs B{y} [active = <0 y> reserved = <x y>] [rollover: active = <0 0> reserved = <0 y>] runs C{x} [active = <0 x>] [resumes] runs A{x} At that stage, both A and C have the same ASID, with deadly consequences. The fix is to preserve reserved ASIDs across rollovers if the CPU doesn't have an active ASID when the rollover occurs. Cc: <stable@vger.kernel.org> # 3.9 Acked-by:

When booting fewer cores than are physically present on a versatile platform (e.g. when passing maxcpus=N on the command line), some secondary cores may remain in the holding pen, which is marked __INIT, as each CPU's gic cpumask is initialised to 0xff, and thus an IPI to any CPU will wake up *all* secondaries. This behaviour is crucial to the GIC cpumask self-discovery. Late in the boot process, the memory comprising the holding pen will be released to the kernel for more general use, and may be overwritten with arbitrary data, which can cause the held secondaries to start behaving unpredictably. This can lead to all manner of odd behaviour from the kernel. As preventing cpus from entering the pen would require invasive changes to the GIC driver and to existing dts used in the wild, we instead remove the __INIT marker from the pen, keeping it around and leaving the unused secondary CPUs dormant.

With this change, we no longer lose the innermost entry in the user-mode part of the call chain. See also the x86 port, which includes the ip. It's possible to partially work around this problem by post-processing the data to use the PERF_SAMPLE_IP value, but this works only if the CPU wasn't in the kernel when the sample was taken.

Since commit 6a1c5312 the user writeable TLS register was zeroed to prevent it from being used as a covert channel between two tasks. There are more and more applications coming to Windows RT, Wine could support them, but mostly they expect to have the thread environment block (TEB) in TPIDRURW. This patch preserves that register per thread instead of clearing it. Unlike the TPIDRURO, which is already switched, the TPIDRURW can be updated from userspace so needs careful treatment in the case that we modify TPIDRURW and call fork(). To avoid this we must always read TPIDRURW in copy_thread. Signed-off-by:

When scheduling an mm on a CPU where it hasn't previously been used, we flush the icache on that CPU so that any code loaded previously on a different core can be safely executed. For cores with hardware broadcasting of cache maintenance operations, this is clearly unnecessary, since the inner-shareable invalidation in __sync_icache_dcache will affect all CPUs. This patch conditionalises the icache flush in switch_mm based on cache_ops_need_broadcast(). Acked-by:

Running an OABI_COMPAT kernel on an SMP platform can lead to fun and games with page aging. If one CPU issues a swi instruction immediately before another CPU decides to mkold the page containing the swi instruction, then we will fault attempting to load the instruction during the vector_swi handler in order to retrieve its immediate field. Since this fault is not currently dealt with by our exception tables, this results in a panic: Unable to handle kernel paging request at virtual address 4020841c pgd = c490c000 [4020841c] *pgd=84451831, *pte=bf05859d, *ppte=00000000 Internal error: Oops: 17 [#1] PREEMPT SMP ARM Modules linked in: hid_sony(O) CPU: 1 Tainted: G W O (3.4.0-perf-gf496dca-01162-gcbcc62b #1) PC is at vector_swi+0x28/0x88 LR is at 0x40208420 This patch wraps all of the swi instruction loads with the USER macro and provides a shared exception table entry which simply rewinds the saved user PC and returns from the system call (without setting tbl, so there's no worries with tracing or syscall restarting). Returning to userspace will re-enter the page fault handler, from where we will probably send SIGSEGV to the current task. Reported-by:

Currently flush_dcache_page() thinks pages as non-mapped if mapping_mapped(mapping) return false. This approach is very coase: - mmap on part of file may cause all pages backed on the file being thought as mmaped - file-backed pages aren't mapped into user space actually if the memory mmaped on the file isn't accessed This patch uses page_mapped() to decide if the page has been mapped. From the attached test code, I find there is much performance improvement(>25%) when accessing page caches via read under this situations, so memcpy benefits a lot from not flushing cache under this situation.

It is common for one sg to include many pages, so mark all these pages as clean to avoid unnecessary flushing on them in set_pte_at() or update_mmu_cache(). The patch might improve loading performance of applciation code a bit.

When CONFIG_ARM_APPENDED_DTB is selected, if the bootloader provides an ATAG_MEM it replaces the memory size and the memory address in the memory node of the device tree. In the case of a system which can handle more than 4GB, the memory node cell size is 4: each data (memory size and memory address) are 64 bits and then use 2 cells. The current code in atags_to_fdt.c made the assumption of a cell size of 2 (one cell for the memory size and one cell for the memory address), this leads to an improper write of the data and ends with a boot hang. This patch writes the memory size and the memory address on the memory node in the device tree depending of the size of the memory node (32 bits or 64 bits). It has been tested in the 2 cases: - with a dtb using skeleton.dtsi - and with a dtb using skeleton64.dtsi Signed-off-by:

Commit 14318efb (ARM: 7587/1: implement optimized percpu variable access) introduces arm's __my_cpu_offset to optimize percpu vaiable access, which really works well on hackbench, but will cause __my_cpu_offset to return garbage value before it is initialized in cpu_init() called by setup_arch, so accessing percpu variable before setup_arch may cause kernel hang. But generic __my_cpu_offset always returns zero before percpu area is brought up, and won't hang kernel. So the patch tries to clear __my_cpu_offset on boot CPU early to avoid boot hang. At least now percpu variable is accessed by lockdep before setup_arch(), and enabling CONFIG_LOCK_STAT or CONFIG_DEBUG_LOCKDEP can trigger kernel hang. Signed-off-by:

Pull MIPS updates from Ralf Baechle: - More work on DT support for various platforms - Various fixes that were to late to make it straight into 3.9 - Improved platform support, in particular the Netlogic XLR and BCM63xx, and the SEAD3 and Malta eval boards. - Support for several Ralink SOC families. - Complete support for the microMIPS ASE which basically reencodes the existing MIPS32/MIPS64 ISA to use non-constant size instructions. - Some fallout from LTO work which remove old cruft and will generally make the MIPS kernel easier to maintain and resistant to compiler optimization, even in absence of LTO. - KVM support. While MIPS has announced hardware virtualization extensions this KVM extension uses trap and emulate mode for virtualization of MIPS32. More KVM work to add support for VZ hardware virtualizaiton extensions and MIPS64 will probably already be merged for 3.11. Most of this has been sitting in -next for a long time. All defconfigs have been build or run time tested except three for which fixes are being sent by other maintainers. Semantic conflict with kvm updates done as per Ralf * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (118 commits) MIPS: Add new GIC clockevent driver.

This fixes a bug where the iscsi class/driver did not do a put_device when a sess/conn device was found. This also simplifies the interface by not having to pass in some arguments that were duplicated and did not need to be exported. Reported-by:

These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them. The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix. Signed-off-by:
