Hardware issue: - Reading register RCPM_IPPDEXPCR1 always return zero, this causes system firmware could not get correct information and wrongly do clock gating for all wakeup source IP during system suspend. Then those IPs will never get chance to wake system. Workaround: - Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8 to allow system firmware's psci method read it and do things accordingly.

This was addressed before through drivers setting the DMA offsets directly, and subsequently changed to calls to dma_direct_set_offset. However that wasn't really meant to be exported to modules (and thus drivers). The duplicated code also led to small inconsistencies across drivers in how we dealt with DT backward compatibility. Move all that DMA setup code into a platform bus notifier to share that code and remove the export on dma_direct_set_offset. * tag 'sunxi-rework-mbus' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mripard/linux: dma-mapping: remove the dma_direct_set_offset export media: sun8i-di: Remove the call to of_dma_configure media: cedrus: Remove the MBUS quirks media: sun6i: Remove the MBUS quirks media: sun4i: Remove the MBUS quirks drm/sun4i: backend: Remove the MBUS quirks soc: sunxi: Deal with the MBUS DMA offsets in a central place drm/sun4i: backend: Fix probe failure with multiple backends Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-10-28clk: samsung: exynos-clkout: convert to module driverKrzysztof Kozlowski1-57/+141
The Exynos clkout driver depends on board input clock (typically XXTI or XUSBXTI), however on Exynos4 boards these clocks were modeled as part of SoC clocks (Exynos4 clocks driver). Obviously this is not proper, but correcting it would break DT backward compatibility. Both drivers - clkout and Exynos4 clocks - register the clock providers with CLK_OF_DECLARE/OF_DECLARE_1 so their order is fragile (in the Makefile clkout is behind Exynos4 clock). It will work only if the Exynos4 clock driver comes up before clkout. A change in DTS adding input clock reference to Exynos4 clocks input PLL, see reverted commit eaf2d2f6895d ("ARM: dts: exynos: add input clock to CMU in Exynos4412 Odroid"), caused probe reorder: the clkout appeared before Exynos4 clock provider. Since clkout depends on Exynos4 clocks and does not support deferred probe, this did not work and caused later failure of usb3503 USB hub probe which needs clkout: [ 5.007442] usb3503 0-0008: unable to request refclk (-517) The Exynos clkout driver is not a critical/core clock so there is actually no problem in instantiating it later, as a regular module. This removes specific probe ordering and adds support for probe deferral.

It was modeled as clock provider instantiated with CLK_OF_DECLARE_DRIVER(). This however brings ordering problems and lack of probe deferral, therefore clkout driver should be converted to a regular module and instantiated as a child of PMU driver to be able to use existing compatibles and address space.

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

2020-10-25kernel/sys.c: fix prototype of prctl_get_tid_address()Rasmus Villemoes1-3/+3
tid_addr is not a "pointer to (pointer to int in userspace)"; it is in fact a "pointer to (pointer to int in userspace) in userspace". So sparse rightfully complains about passing a kernel pointer to put_user().

2020-10-25mm: remove kzfree() compatibility definitionEric Biggers6-8/+6
Commit 453431a54934 ("mm, treewide: rename kzfree() to kfree_sensitive()") renamed kzfree() to kfree_sensitive(), but it left a compatibility definition of kzfree() to avoid being too disruptive. Since then a few more instances of kzfree() have slipped in. Just get rid of them and remove the compatibility definition once and for all.

This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
