2019-01-04arm64: compat: Hook up io_pgetevents() for 32-bit tasksWill Deacon
Commit 73aeb2cbcdc9 ("ARM: 8787/1: wire up io_pgetevents syscall") hooked up the io_pgetevents() system call for 32-bit ARM, so we can do the same for the compat wrapper on arm64. Signed-off-by: Will Deacon <will.deacon@arm.com>
2019-01-04arm64: compat: Don't pull syscall number from regs in arm_compat_syscallWill Deacon
The syscall number may have been changed by a tracer, so we should pass the actual number in from the caller instead of pulling it from the saved r7 value directly.

2019-01-04arm64: compat: Avoid sending SIGILL for unallocated syscall numbersWill Deacon
The ARM Linux kernel handles the EABI syscall numbers as follows: 0 - NR_SYSCALLS-1 : Invoke syscall via syscall table NR_SYSCALLS - 0xeffff : -ENOSYS (to be allocated in future) 0xf0000 - 0xf07ff : Private syscall or -ENOSYS if not allocated > 0xf07ff : SIGILL Our compat code gets this wrong and ends up sending SIGILL in response to all syscalls greater than NR_SYSCALLS which have a value greater than 0x7ff in the bottom 16 bits. Fix this by defining the end of the ARM private syscall region and checking the syscall number against that directly. Update the comment while we're at it.

2019-01-04arm64/sve: Disentangle <uapi/asm/ptrace.h> from <uapi/asm/sigcontext.h>Dave Martin
Currently, <uapi/asm/sigcontext.h> provides common definitions for describing SVE context structures that are also used by the ptrace definitions in <uapi/asm/ptrace.h>. For this reason, a #include of <asm/sigcontext.h> was added in ptrace.h, but it this turns out that this can interact badly with userspace code that tries to include ptrace.h on top of the libc headers (which may provide their own shadow definitions for sigcontext.h). To make the headers easier for userspace to consume, this patch bounces the common definitions into an __SVE_* namespace and moves them to a backend header <uapi/asm/sve_context.h> that can be included by the other headers as appropriate. This should allow ptrace.h to be used alongside libc's sigcontext.h (if any) without ill effects. This should make the situation unambiguous: <asm/sigcontext.h> is the header to include for the sigframe-specific definitions, while <asm/ptrace.h> is the header to include for ptrace-specific definitions. To avoid conflicting with existing usage, <asm/sigcontext.h> remains the canonical way to get the common definitions for SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the kernel: relying on these being defined as a side effect of including just <asm/ptrace.h> was never intended to be safe.

2019-01-04arm64/sve: ptrace: Fix SVE_PT_REGS_OFFSET definitionDave Martin
SVE_PT_REGS_OFFSET is supposed to indicate the offset for skipping over the ptrace NT_ARM_SVE header (struct user_sve_header) to the start of the SVE register data proper. However, currently SVE_PT_REGS_OFFSET is defined in terms of struct sve_context, which is wrong: that structure describes the SVE header in the signal frame, not in the ptrace regset. This patch fixes the definition to use the ptrace header structure struct user_sve_header instead. By good fortune, the two structures are the same size anyway, so there is no functional or ABI change.

2019-01-04powerpc: Drop use of 'type' from access_ok()Mathieu Malaterre
In commit 05a4ab823983 ("powerpc/uaccess: fix warning/error with access_ok()") an attempt was made to remove a warning by referencing the variable `type`. However in commit 96d4f267e40f ("Remove 'type' argument from access_ok() function") the variable `type` has been removed, breaking the build: arch/powerpc/include/asm/uaccess.h:66:32: error: ‘type’ undeclared (first use in this function) This essentially reverts commit 05a4ab823983 ("powerpc/uaccess: fix warning/error with access_ok()") to fix the error.

2019-01-04cpufreq: scpi/scmi: Fix freeing of dynamic OPPsViresh Kumar
Since the commit 2a4eb7358aba "OPP: Don't remove dynamic OPPs from _dev_pm_opp_remove_table()", dynamically created OPP aren't automatically removed anymore by dev_pm_opp_cpumask_remove_table(). This affects the scpi and scmi cpufreq drivers which no longer free OPPs on failures or on invocations of the policy->exit() callback. Create a generic OPP helper dev_pm_opp_remove_all_dynamic() which can be called from these drivers instead of dev_pm_opp_cpumask_remove_table(). In dev_pm_opp_remove_all_dynamic(), we need to make sure that the opp_list isn't getting accessed simultaneously from other parts of the OPP core while the helper is freeing dynamic OPPs, i.e. we can't drop the opp_table->lock while traversing through the OPP list. And to accomplish that, this patch also creates _opp_kref_release_unlocked() which can be called from this new helper with the opp_table lock already held.

Last but not least this also officially allows calling dma_sync_single_* for mappings created using dma_map_page, which is perfectly fine given that the sync calls only take a dma_addr_t, but not a virtual address or struct page.

2019-01-03Remove 'type' argument from access_ok() functionLinus Torvalds
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This code relies on IOSF_MBI and IOSF_MBI depends on PCI. For this reason, add a direct dependency on CONFIG_PCI to the IOSF_MBI driver.

2019-01-03ALSA: compress: prevent potential divide by zero bugsDan Carpenter
The problem is seen in the q6asm_dai_compr_set_params() function: ret = q6asm_map_memory_regions(dir, prtd->audio_client, prtd->phys, (prtd->pcm_size / prtd->periods), ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ prtd->periods); In this code prtd->pcm_size is the buffer_size and prtd->periods comes from params->buffer.fragments. If we allow the number of fragments to be zero then it results in a divide by zero bug. One possible fix would be to use prtd->pcm_count directly instead of using the division to re-calculate it. But I decided that it doesn't really make sense to allow zero fragments. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-01-03ASoC: qdsp6: q6asm-dai: Fix a small memory leakDan Carpenter
We can't return directly if snd_dma_alloc_pages() fails; we first need to free prtd->audio_client and prtd. Fixes: 22930c79ac5c ("ASoC: qdsp6: q6asm-dai: Add support to compress offload") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@kernel.org>

The q6asm_fe_dais[] array has MAX_SESSIONS (8) elements so the > comparison should be >= or we access one element beyond the end of the array.

2019-01-03ASoC: pcm512x: Fix a double unlock in pcm512x_digital_mute()Dan Carpenter
We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row. I re-wrote the error handling to use "goto unlock;" instead of returning directly. Hopefully, it makes the code a little simpler.

2019-01-03ASoC: Intel: Haswell/Broadwell: fix setting for .dynamic fieldRander Wang
For some reason this field was set to zero when all other drivers use .dynamic = 1 for front-ends. This change was tested on Dell XPS13 and has no impact with the existing legacy driver. The SOF driver also works with this change which enables it to override the fixed topology.
