2021-02-10x86/fault/32: Move is_f00f_bug() to do_kern_addr_fault()Andy Lutomirski
bad_area() and its relatives are called from many places in fault.c, and exactly one of them wants the F00F workaround. __bad_area_nosemaphore() no longer contains any kernel fault code, which prepares for further cleanups.

2021-02-10x86/fault: Fold mm_fault_error() into do_user_addr_fault()Andy Lutomirski
mm_fault_error() is logically just the end of do_user_addr_fault(). Combine the functions. This makes the code easier to read. Most of the churn here is from renaming hw_error_code to error_code in do_user_addr_fault(). This makes no difference at all to the generated code (objdump -dr) as compared to changing noinline to __always_inline in the definition of mm_fault_error().

iwl_acpi_get_wifi_pkg() may return a valid pointer (meaning success), while `tbl_rev` is invalid (equel to 1). In this case, we will treat that as an error. Subsequent "users" of this "error code" may either check for nonzero (good; pointers are never zero) or negative (bad; pointers may be "positive") fix that by splitting the if statement.

Some change conflicts apparently cause a confusion between a local variable being used to send the PPAG command and the introduction of a union for this command.

2021-02-10iwlwifi: mvm: fix the type we use in the PPAG table validity checksLuca Coelho
The value we receive from ACPI is a long long unsigned integer but the values should be treated as signed char. When comparing the received value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison, so the negative value would actually be treated as a very high number.

2021-02-10x86/fault: Fix AMD erratum #91 errata fixup for user codeAndy Lutomirski
The recent rework of probe_kernel_address() and its conversion to get_kernel_nofault() inadvertently broke is_prefetch(). Before this change, probe_kernel_address() was used as a sloppy "read user or kernel memory" helper, but it doesn't do that any more. The new get_kernel_nofault() reads *kernel* memory only, which completely broke is_prefetch() for user access. Adjust the code to the correct accessor based on access mode. The manual address bounds check is no longer necessary, since the accessor helpers (get_user() / get_kernel_nofault()) do the right thing all by themselves. As a bonus, by using the correct accessor, the open-coded address bounds check is not needed anymore.

2021-02-10x86/xen: Drop USERGS_SYSRET64 paravirt callJuergen Gross
USERGS_SYSRET64 is used to return from a syscall via SYSRET, but a Xen PV guest will nevertheless use the IRET hypercall, as there is no sysret PV hypercall defined. So instead of testing all the prerequisites for doing a sysret and then mangling the stack for Xen PV again for doing an iret just use the iret exit from the beginning. This can easily be done via an ALTERNATIVE like it is done for the sysenter compat case already. It should be noted that this drops the optimization in Xen for not restoring a few registers when returning to user mode, but it seems as if the saved instructions in the kernel more than compensate for this drop (a kernel build in a Xen PV guest was slightly faster with this patch applied). While at it remove the stale sysret32 remnants.

2021-02-10drm/sun4i: dw-hdmi: Fix max. frequency for H6Jernej Skrabec
It turns out that reasoning for lowering max. supported frequency is wrong. Scrambling works just fine. Several now fixed bugs prevented proper functioning, even with rates lower than 340 MHz. Issues were just more pronounced with higher frequencies. Fix that by allowing max. supported frequency in HW and fix the comment.

2021-02-10drm/sun4i: Fix H6 HDMI PHY configurationJernej Skrabec
As it turns out, vendor HDMI PHY driver for H6 has a pretty big table of predefined values for various pixel clocks. However, most of them are not useful/tested because they come from reference driver code. Vendor PHY driver is concerned with only few of those, namely 27 MHz, 74.25 MHz, 148.5 MHz, 297 MHz and 594 MHz. These are all frequencies for standard CEA modes. Fix sun50i_h6_cur_ctr and sun50i_h6_phy_config with the values only for aforementioned frequencies. Table sun50i_h6_mpll_cfg doesn't need to be changed because values are actually frequency dependent and not so much SoC dependent. See i.MX6 documentation for explanation of those values for similar PHY.

2021-02-10drm/sun4i: dw-hdmi: always set clock rateJernej Skrabec
As expected, HDMI controller clock should always match pixel clock. In the past, changing HDMI controller rate would seemingly worsen situation. However, that was the result of other bugs which are now fixed. Fix that by removing set_rate quirk and always set clock rate.

2021-02-10drm/sun4i: tcon: set sync polarity for tcon1 channelJernej Skrabec
Channel 1 has polarity bits for vsync and hsync signals but driver never sets them. It turns out that with pre-HDMI2 controllers seemingly there is no issue if polarity is not set. However, with HDMI2 controllers (H6) there often comes to de-synchronization due to phase shift. This causes flickering screen. It's safe to assume that similar issues might happen also with pre-HDMI2 controllers. Solve issue with setting vsync and hsync polarity. Note that display stacks with tcon top have polarity bits actually in tcon0 polarity register.

2021-02-10ARM: dts: add Ebang EBAZ4205 device treeMichael Walle
The Ebang EBAZ4205 is a simple board based on the Xilinx Zynq-7000 SoC. Its features are: - one serial port - 256 MB RAM - 128 MB NAND flash - SDcard slot - IP101GA 10/100 Mbit Ethernet PHY (connected to PL IOs) - two LEDs (connected to PL IOs) - one Push Button (connect to PL IOs) - (optional) RTC - (optional) Input voltage supervisor The NAND flash is not supported in mainline linux yet. Unfortunately, the PHY is connected via the PL, thus for working ethernet the FPGA has to be configured. Also, depending on the board variant, the PHY has no external crystal and its clock needs to be driven by the PL. FCLK3 is used for this and is kept enabled.
