Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.

[Test Code] config A bool "a" config B bool "b" imply A depends on A In the code above, Kconfig cannot calculate the symbol values correctly due to the circular dependency. For example, allyesconfig followed by syncconfig results in an odd behavior because CONFIG_B becomes visible in syncconfig. $ make allyesconfig scripts/kconfig/conf --allyesconfig Kconfig # # configuration written to .config # $ cat .config # # Automatically generated file; DO NOT EDIT. # Main menu # CONFIG_A=y $ make syncconfig scripts/kconfig/conf --syncconfig Kconfig * * Restart config... * * * Main menu * a (A) [Y/n/?] y b (B) [N/y/?] (NEW) To detect this correctly, sym_check_expr_deps() should recurse to not only sym->rev_dep.expr but also sym->implied.expr . At this moment, sym_check_print_recursive() cannot distinguish 'select' and 'imply' since it does not know the precise context where the recursive dependency has been hit. This will be solved by the next commit. In fact, even the document and the unit-test are confused. Using 'imply' does not solve recursive dependency since 'imply' addresses the unmet direct dependency, which 'select' could cause.

These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances. However, according to Thierry's view, https://www.spinics.net/lists/linux-ide/msg55357.html some hardware-specific drivers already use their own resets, and the common reset make a path to occur double controls of resets. The ahci_platform_get_resources() can get and control the reset only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

The latter function requires that the "ap->lock" lock is held which needs to be taken with disabled interrupts. There is no need have to have ata_sff_data_xfer_noirq() which invokes ata_sff_data_xfer32() with disabled interrupts because at this point the interrupts are already disabled.

The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.

Summary: - add support for deferred console takeover, when enabled defers fbcon taking over the console from the dummy console until the first text is displayed on the console - together with the "quiet" kernel commandline option this allows fbcon to still be used together with a smooth graphical bootup (Hans de Goede) - improve console locking debugging code (Thomas Zimmermann) - copy the ACPI BGRT boot graphics to the framebuffer when deferred console takeover support is used in efifb driver (Hans de Goede) - update udlfb driver - fix lost console when the user unplugs a USB adapter, fix the screen corruption issue, fix locking and add some performance optimizations (Mikulas Patocka) - update pxafb driver - fix using uninitialized memory, switch to devm_* API, handle initialization errors and add support for lcd-supply regulator (Daniel Mack) - add support for boards booted with a DeviceTree in pxa3xx_gcu driver (Daniel Mack) - rename omap2 module to omap2fb.ko to avoid conflicts with omap1 driver (Arnd Bergmann) - enable ACPI-based enumeration for goldfishfb driver (Yu Ning) - fix goldfishfb driver to make user space Android code use 60 fps (Christoffer Dall) - print big fat warning when nomodeset kernel parameter is used in vgacon driver (Lyude Paul) - remove VLA usage from fsl-diu-fb driver (Kees Cook) - misc fixes (Julia Lawall, Geert Uytterhoeven, Fredrik Noring, Yisheng Xie, Dan Carpenter, Daniel Vetter, Anton Vasilyev, Randy Dunlap, Gustavo A.

In order to balance the bandwidth, mt2712 has two M4Us, two smi-commons, 10 smi-larbs. and mt2712 is also MTK IOMMU gen2 which uses ARM Short-Descriptor translation table format. The mt2712 M4U-SMI HW diagram is as below: EMI | ------------------------------------ | | M4U0 M4U1 | | smi-common0 smi-common1 | | ------------------------- -------------------------------- | | | | | | | | | | | | | | | | | | | | larb0 larb1 larb2 larb3 larb6 larb4 larb5 larb7 larb8 larb9 disp0 vdec cam venc jpg mdp1/disp1 mdp2/disp2 mdp3 vdo/nr tvd All the connections are HW fixed, SW can NOT adjust it.
