As previously reported, some userspace applications depend on bogomips showed by /proc/cpuinfo. Although there is much less legacy impact on aarch64 than arm, it does break libvirt. This patch reverts commit 326b16db ("arm64: delay: don't bother reporting bogomips in /proc/cpuinfo"), but with some tweak due to context change and without the pr_info(). Fixes: 326b16db ("arm64: delay: don't bother reporting bogomips in /proc/cpuinfo") Signed-off-by:

This was totally lost when I originally created the atomic helpers. We probably should also check possible_clones in the helpers, but since the legacy ones didn't do that this is for a separate patch. Reported-by:

This reverts commit 6764e9f8 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Thu Aug 27 15:44:06 2015 +0200 drm/i915: skip modeset if compatible for everyone. Bring back the i915.fastboot module parameter, disabled by default, due to backlight regression on Chromebook Pixel 2015. Apparently the firmware of the Chromebook in question enables the panel but disables backlight to avoid a brief garbage scanout upon loading the kernel/module. With fastboot, we leave the backlight untouched, in this case disabled. The user would have to do a modeset (i.e. not just crank up the brightness) to enable the backlight. There is no clean fix readily available, so get back to the drawing board by reverting. [N.B. The reference below is for when the thread was included on public lists, and some of the context had already been dropped by then.] Reported-and-tested-by:

A newly introduced function in include/net/sock.h passes a const argument to smp_load_acquire: static inline int sk_state_load(const struct sock *sk) { return smp_load_acquire(&sk->sk_state); } This cause an allmodconfig build failure, since our underlying load-acquire implementation does not handle const types correctly: include/net/sock.h: In function 'sk_state_load': ./arch/arm64/include/asm/barrier.h:71:3: error: read-only variable '___p1' used as 'asm' output asm volatile ("ldarb %w0, %1" \ This patch fixes the problem by reusing the trick in READ_ONCE that loads via a non-const member of an anonymous union. This has the advantage of allowing us to use smp_load_acquire on packed structures (e.g. arch_spinlock_t) as well as primitive types.

When diagnosing a unrelated bug for someone on irc, it would seem the hardware can be brought up by the BIOS with the embedded displayport using the SPLL for spread spectrum. Right now this is not handled well in i915, and it calculates the crtc needs to be reprogrammed on the first modeset without SSC, but the SPLL itself was kept active. Fix this by exposing SPLL as a shared pll that will not be returned by intel_get_shared_dpll; you have to know it exists to use it. Changes since v1: - Create a separate dpll_hw_state.spll for spll, and use separate pll functions for spll. Tested-by:

The permissions in mark_rodata_ro trigger a build error with STRICT_MM_TYPECHECKS. Fix this by introducing PAGE_KERNEL_ROX for the same reasons as PAGE_KERNEL_RO. From Ard: "PAGE_KERNEL_EXEC has PTE_WRITE set as well, making the range writeable under the ARMv8.1 DBM feature, that manages the dirty bit in hardware (writing to a page with the PTE_RDONLY and PTE_WRITE bits both set will clear the PTE_RDONLY bit in that case)" Signed-off-by:

The asynchronous, merged implementations of AES in CBC, CTR and XTS modes are preferred when available (i.e., when instantiating ablkciphers explicitly). However, the synchronous core AES cipher combined with the generic CBC mode implementation will produce a 'cbc(aes)' blkcipher that is callable asynchronously as well. To prevent this implementation from being used when the accelerated asynchronous implemenation is also available, lower its priority to 250 (i.e., below the asynchronous module's priority of 300).

As pointed out by Russell King in response to the proposed ARM version of this code, the sequence to switch between the UEFI runtime mapping and current's actual userland mapping (and vice versa) is potentially unsafe, since it leaves a time window between the switch to the new page tables and the TLB flush where speculative accesses may hit on stale global TLB entries. So instead, use non-global mappings, and perform the switch via the ordinary ASID-aware context switch routines. Signed-off-by:

With gen < 9 we have had always 50Mhz units as our hw ratio. With gen >= 9 the hw ratio changed to 16.667Mhz (50/3). The result was that our gpu frequency tracing started to output values 3 times larger than expected due to hardcoded scaling value. Fix this by using Use intel_gpu_freq() when generating Mhz value from ratio for 'intel_gpu_freq_change' trace event.
