Commit ce48b210 "powerpc: Add VSX context save/restore, ptrace and signal support" expanded the 'vmx_reserve' array element to contain 101 double words, but the comment block above was not updated. Also reorder the constants in the array size declaration to reflect the logic mentioned in the comment block above. This change helps in explaining how the HW registers are represented in the array. But no functional change. Signed-off-by:

Currently tm_orig_msr is getting used during process context switch only. Then there is ckpt_regs which saves the checkpointed userspace context The MSR slot contained in ckpt_regs structure can be used during process context switch instead of tm_orig_msr, thus allowing us to drop it from thread_struct structure. This patch does that change. Acked-by:

This patch adds support for OPAL EPOW (Environmental and Power Warnings) and DPO (Delayed Power Off) events for the PowerNV platform. These events are generated on FSP (Flexible Service Processor) based systems. EPOW events are generated due to various critical system conditions that require system shutdown. A few examples of these conditions are high ambient temperature or system running on UPS power with low UPS battery. DPO event is generated in response to admin initiated system shutdown request. Upon receipt of EPOW and DPO events the host kernel invokes orderly_poweroff() for performing graceful system shutdown. Signed-off-by:

When releasing PE for SRIOV VF, the PE is forced to be frozen wrongly. When the same PE is picked for another VF, it won't work anyhow. The patch fixes the issue by unfreezing, not freezing the VF PE when releasing it. Signed-off-by:

The PELTV of PF PE should include VF PE, which is missed by current code, so that the VF PE is frozen automatically when freezing PF PE. The patch fixes the PELTV of PF PE to include VF PE. Signed-off-by:

On PHB3, PE might be reserved in advance to reflect the M64 segments consumed by the PE according to M64 BARs (exclude VF BARs) of the PCI devices included in the PE. The PE is picked based on M64 BARs instead of the bridge's M64 windows, which might include VF BARs. Otherwise, wrong PE could be picked. The patch calculates the used M64 segments and PE numbers according to the M64 BARs, excluding VF BARs, of PCI devices in one particular PE, instead of the bridge's M64 windows. Then the right PE number is picked. Signed-off-by:

Gavin Shan authored
On PHB3, some PEs might be reserved in advance to reflect the M64 segments consumed by those PEs. We're reserving PEs based on the M64 window of root port, which might contain VF BAR. The PEs for VFs are allocated dynamically, not reserved based on the consumed M64 segments. So the M64 window of root port isn't reliable for the task. Instead, we go through M64 BARs (VF BARs excluded) of PCI devices under the specified root bus and reserve PEs accordingly, as the patch does. Signed-off-by:

Gavin Shan authored
The PE numbers are reserved according to root port's M64 window, which is aligned to M64 segment finely. So one PE shouldn't be reserved for multiple times. We will reserve PE numbers according to the M64 BARs of PCI device in subsequent patches, which aren't aligned to M64 segment size finely. It means one particular PE could be reserved for multiple times. The patch allows one PE to be reserved for multiple times and we print the warning message at debugging level. Signed-off-by:

The encoding of the lengths in the ibm_architecture_vec array is "interesting" to say the least. It's non-obvious how the number of bytes we provide relates to the length value. In fact we already got it wrong once, see 11e9ed43 "Fix up ibm_architecture_vec definition". So add some macros to make it (hopefully) clearer. These at least have the property that the integer present in the code is equal to the number of bytes that follows it. Signed-off-by:

To support "hybrid" DMA ops in a subsequent patch, we will need both a direct DMA offset and an iommu pointer. Those are currently exclusive (a union), so change them to be separate fields. While there, also type iommu_table_base properly and make exist only on CONFIG_PPC64 since it's not referenced on 32-bit at all. Signed-off-by:

A precision of 16 (%.16llx) has the same effect as a field width of 16 along with passing the 0 flag (%016llx), but the latter is much more common in the kernel tree. Update cxl to use that. Signed-off-by:

C99 says that a precision given as simply '.' with no following digits or * should be interpreted as 0. The kernel's printf implementation, however, treats this case as if the precision was omitted. C99 also says that if both the precision and value are 0, no digits should be printed. Even if the kernel followed C99 to the letter, I don't think that would be particularly useful in these cases. For consistency with most other format strings in the file, use an explicit precision of 16 and add a 0x prefix. Signed-off-by:

This reverts commit dec4f799. Jörg Otte reports a NULL pointder dereference due to this commit, as 'crtc_state' very much can be NULL: crtc_state = state->base.state ? intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL; So the change to test 'crtc_state->base.active' cannot possibly be correct as-is. There may be some other minimal fix (like just checking crtc_state for NULL), but I'm just reverting it now for the rc2 release, and people like Daniel Vetter who actually know this code will figure out what the right solution is in the longer term.

Normally opening a file, unlinking it and then closing will have the inode freed upon close() (provided that it's not otherwise busy and has no remaining links, of course). However, there's one case where that does *not* happen. Namely, if you open it by fhandle with cold dcache, then unlink() and close(). In normal case you get d_delete() in unlink(2) notice that dentry is busy and unhash it; on the final dput() it will be forcibly evicted from dcache, triggering iput() and inode removal. In this case, though, we end up with *two* dentries - disconnected (created by open-by-fhandle) and regular one (used by unlink()). The latter will have its reference to inode dropped just fine, but the former will not - it's considered hashed (it is on the ->s_anon list), so it will stay around until the memory pressure will finally do it in. As the result, we have the final iput() delayed indefinitely. It's trivial to reproduce - void flush_dcache(void) { system("mount -o remount,rw /"); } static char buf[20 * 1024 * 1024]; main() { int fd; union { struct file_handle f; char buf[MAX_HANDLE_SZ]; } x; int m; x.f.handle_bytes = sizeof(x); chdir("/root"); mkdir("foo", 0700); fd = open("foo/bar", O_CREAT | O_RDWR, 0600); close(fd); name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0); flush_dcache(); fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR); unlink("foo/bar"); write(fd, buf, sizeof(buf)); system("df ."); /* 20Mb eaten */ close(fd); system("df ."); /* should've freed those 20Mb */ flush_dcache(); system("df ."); /* should be the same as #2 */ } will spit out something like Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 283282 21692 93% / - inode gets freed only when dentry is finally evicted (here we trigger than by remount; normally it would've happened in response to memory pressure hell knows when).

Granted these are slightly large for a -rc update. They have been out for review in one form or another since the end of May and were deferred from the merge window while we settled on the "PMEM API" for the PMEM-mode nvdimm driver (ie memremap_pmem, memcpy_to_pmem, and wmb_pmem). Now that those apis are merged we implement them in the BLK driver to guarantee that mmio aperture moves stay ordered with respect to incoming read/write requests, and that writes are flushed through those mmio-windows and platform-buffers to be persistent on media. These pass the sub-system unit tests with the updates to tools/testing/nvdimm, and have received a successful build-report from the kbuild robot (468 configs).

commit 66fc1303 ("mm: shmem_zero_setup skip security check and lockdep conflict with XFS") caused a regression for SELinux by disabling any SELinux checking of mprotect PROT_EXEC on shared anonymous mappings. However, even before that regression, the checking on such mprotect PROT_EXEC calls was inconsistent with the checking on a mmap PROT_EXEC call for a shared anonymous mapping. On a mmap, the security hook is passed a NULL file and knows it is dealing with an anonymous mapping and therefore applies an execmem check and no file checks. On a mprotect, the security hook is passed a vma with a non-NULL vm_file (as this was set from the internally-created shmem file during mmap) and therefore applies the file-based execute check and no execmem check. Since the aforementioned commit now marks the shmem zero inode with the S_PRIVATE flag, the file checks are disabled and we have no checking at all on mprotect PROT_EXEC. Add a test to the mprotect hook logic for such private inodes, and apply an execmem check in that case. This makes the mmap and mprotect checking consistent for shared anonymous mappings, as well as for /dev/zero and ashmem. Cc: <stable@vger.kernel.org> # 4.1.x Signed-off-by:
