On x86, we *do* still use the non-NOP rmb()/wmb() for IO barriers, but even that is generally questionable. Leave them around as historial unless somebody can point to a case where they care about the performance, but tweak the comment so people don't think they are strictly required in all cases.

ADDL clobbers flags (such as CF) but barrier.h didn't tell this to GCC. Historically, GCC doesn't need one on x86, and always considers flags clobbered. We are probably missing the cc clobber in a *lot* of places for this reason. But even if not necessary, it's probably a good thing to add for documentation, and in case GCC semantcs ever change.

The first is a cut and paste issue that changed the amount of stack to skip when tracing a stack dump from 0 to 6, which basically made the stack disappear for small stack traces. The second fix is just removing an unused field in a struct that is no longer used, and currently just wastes space. The third is another cut-and-paste fix that had a tracepoint recording the wrong field (it was recording the previous field a second time). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJWqibPAAoJEKKk/i67LK/8/NkH/3M6WB7RIiMMd4O403imbKcs yIH0j9vH6Z5hwoAUUr0bEw+gHVgzsiRky5z+fP0f1J3QdVAdgEig6RgQtIbWRynu i7fohNAiSMBob0wOIHTohQDKkQjvgoO9gO5S8nY6Axgpf4iqOTy3RF2a/gcltULY qdgy9A0vLk6yMbP6c0P+kEzg4y+Q90DsUh8YzQKW7F1EJPneDmNdug3VM16gefTR 4yrodSBHxr8NV3kAhN8G7FjWmK5cBDFwD66vsti64mKVCW00hjYRCQ+5BrgQ7h0V EDC7kHisckLb415SQxe8XdF4fKbfE1PuQYZhjTo02hx9XCMeyxDWbjTF2PrZCHw= =gab6 -----END PGP SIGNATURE----- Merge tag 'trace-v4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull minor tracing fixes from Steven Rostedt: "This includes three minor fixes, mostly due to cut-and-paste issues.

Calling apply_to_page_range with an empty range results in a BUG_ON from the core code.

The kernel now always uses vector registers when available, however KVM has special logic if support is really enabled for a guest. If support is disabled, guest_fpregs.fregs will only contain memory for the fpu. The kernel, however, will store vector registers into that area, resulting in crazy memory overwrites. Simply extending that area is not enough, because the format of the registers also changes. We would have to do additional conversions, making the code even more complex. Therefore let's directly use one place for the vector/fpu registers + fpc (in kvm_run). We just have to convert the data properly when accessing it. This makes current code much easier. Please note that vector/fpu registers are now always stored to vcpu->run->s.regs.vrs. Although this data is visible to QEMU and used for migration, we only guarantee valid values to user space when KVM_SYNC_VRS is set. As that is only the case when we have vector register support, we are on the safe side. Fixes:

adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419

module libahci: unsupported RELA relocation: 275

By default the aarch64 gcc generates .eh_frame sections. Unlike .debug_frame sections, the .eh_frame sections are loaded into memory when the associated code is loaded. On an example kernel being built with this default the .eh_frame section in vmlinux used an extra 1.7MB of memory. The x86 disables the creation of the .eh_frame section. The aarch64 should probably do the same to save some memory. Signed-off-by: William Cohen <wcohen@redhat.com> Signed-off-by: Will Deacon <will.deacon@arm.com>

This adds micro-benchmarks useful for tuning virtio ring layouts.

Currently, set_pte_at() only checks the software PTE_WRITE bit for user mappings when it sets or clears the hardware PTE_RDONLY accordingly. The kernel ptes are written directly without any modification, relying solely on the protection bits in macros like PAGE_KERNEL. However, modifying kernel pte attributes via pte_wrprotect() would be ignored by set_pte_at(). Since pte_wrprotect() does not set PTE_RDONLY (it only clears PTE_WRITE), the new permission is not taken into account. This patch changes set_pte_at() to adjust the read-only permission for kernel ptes as well. As a side effect, existing PROT_* definitions used for kernel ioremap*() need to include PTE_DIRTY | PTE_WRITE.

The Performance Monitors extension is an optional feature of the
AArch64 architecture, therefore, in order to access Performance
Monitors registers safely, the kernel should detect the architected
PMU unit presence through the ID_AA64DFR0_EL1 register PMUVer field
before accessing them.
This patch implements a guard by reading the ID_AA64DFR0_EL1 register
PMUVer field to detect the architected PMU presence and prevent accessing
PMU system registers if the Performance Monitors extension is not
implemented in the core.

When switching from the early KASAN shadow region, which maps the entire shadow space read-write, to the permanent KASAN shadow region, which uses a zero page to shadow regions that are not subject to instrumentation, the lowest level table kasan_zero_pte[] may be reused unmodified, which means that the mappings of the zero page that it contains will still be read-write. So update it explicitly to map the zero page read only when we activate the permanent mapping.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.
The executive summary:
- ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
- Avoid useless rebuilds for zboot.
- jz4780: Add NEMC, BCH and NAND device tree nodes
- Initial support for the MicroChip's DT platform. As all the device
drivers are missing this is still of limited use.
- Some Loongson3 cleanups.
- The unavoidable whitespace polishing.
- Reduce clock skew when synchronizing the CPU cycle counters on CPU
startup.
- Add MIPS R6 fixes.
- Lots of cleanups across arch/mips as fallout from KVM.
- Lots of minor fixes and changes for IEEE 754-2008 support to the
FPU emulator / fp-assist software.
- Minor Ralink, BCM47xx and bcm963xx platform support improvments.
- Support SMP on BCM63168"

If we detect that there is nothing to do just set the flag and do not
check if it was already set before. Races really do not matter. If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.
