| Message-ID | <se62f-6Q9-73@gated-at.bofh.it> |
| In reply to | #1476852 |
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: James Hogan <james.hogan@imgtec.com>
commit 3146bc64d12377a74dbda12b96ea32da3774ae07 upstream.
AT_VECTOR_SIZE_ARCH should be defined with the maximum number of
NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined
for arm64 at all even though ARCH_DLINFO will contain one NEW_AUX_ENT
for the VDSO address.
This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for
AT_BASE_PLATFORM which arm64 doesn't use, but lets define it now and add
the comment above ARCH_DLINFO as found in several other architectures to
remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to
date.

commit 68187872c76a96ed4db7bfb064272591f02e208b upstream.
Since instruction decoder now supports EVEX-encoded instructions, two fixes
are needed to correctly handle them in uprobes.
Extended bits for MODRM.rm field need to be sanitized just like we do it
for VEX3, to avoid encoding wrong register for register-relative access.
EVEX has _two_ extended bits: b and x. Theoretically, EVEX.x should be
ignored by the CPU (since GPRs go only up to 15, not 31), but let's be
paranoid here: proper encoding for register-relative access
should have EVEX.x = 1.
Secondly, we should fetch vex.vvvv for EVEX too.
This is now super easy because instruction decoder populates
vex_prefix.bytes[2] for all flavors of (e)vex encodings, even for VEX2.

| Message-ID | <se6bU-6U4-27@gated-at.bofh.it> |
| In reply to | #1476852 |
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
commit c17b1f42594eb71b8d3eb5a6dfc907a7eb88a51d upstream.
We account HugeTLB's shared page table to all processes who share it.
The accounting happens during huge_pmd_share().
If somebody populates pud entry under us, we should decrease pagetable's
refcount and decrease nr_pmds of the process.
By mistake, I increase nr_pmds again in this case. :-/ It will lead to
"BUG: non-zero nr_pmds on freeing mm: 2" on process' exit.
Let's fix this by increasing nr_pmds only when we're sure that the page
table will be used.

| Message-ID | <se6bV-6U4-51@gated-at.bofh.it> |
| In reply to | #1476852 |
4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Williams <dan.j.williams@intel.com> commit d8d378fa1a0c98ecb50ca52c9bf3bc14e25aa2d2 upstream. The unit tests crash when hotplug races the previous probe. This race requires that the loading of the nfit_test module be terminated with SIGTERM, and the module to be unloaded while the ars scan is still running. In contrast to the normal nfit driver, the unit test calls acpi_nfit_init() twice to simulate hotplug, whereas the nominal case goes through the acpi_nfit_notify() event handler. The acpi_nfit_notify() path is careful to flush the previous region registration before servicing the hotplug event. The unit test was missing this guarantee.
