The Armada 3700 SPI controller has 2 ranges of prescaler coefficients. One ranging from 0 to 15 by steps of 1, and one ranging from 0 to 30 by steps of 2. This commit fixes the prescaler coefficients that are over 15 so that it uses the correct range of values. The prescaling coefficient is rounded to the upper value if it is odd. This was tested on Espressobin with spidev and a locigal analyser.

This reverts commit 5c38602d83e584047906b41b162ababd4db4106d. Interrupts can't be enabled early because the register saves are done on the thread stack prior to switching to the IRQ stack. This caused stack overflows and the thread stack needed increasing to 32k. Even then, stack overflows still occasionally occurred. Background: Even with a 32 kB thread stack, I have seen instances where the thread stack overflowed on the mx3210 buildd. Detection of stack overflow only occurs when we have an external interrupt. When an external interrupt occurs, we switch to the thread stack if we are not already on a kernel stack. Then, registers and specials are saved to the kernel stack. The bug occurs in intr_return where interrupts are reenabled prior to returning from the interrupt. This was done incase we need to schedule or deliver signals. However, it introduces the possibility that multiple external interrupts may occur on the thread stack and cause a stack overflow. These might not be detected and cause the kernel to misbehave in random ways. This patch changes the code back to only reenable interrupts when we are going to schedule or deliver signals. As a result, we generally return from an interrupt before reenabling interrupts. This minimizes the growth of the thread stack.

[Linux-stable-mirror] [PATCH] Revert "ipmi_si: fix memory leak on new_smi"

by John Einar Reitan

This reverts commit c97e41076a298dbc4e910c33048e553658388eed, which incorrectly was taken from upstream c0a32fe13cd323ca9420500b16fd69589c9ba91e. The referenced memory leak doesn't exist on the 4.14 stable branch as the new logic of doing the kzalloc hasn't moved to this function. By adding this kfree we actually end up doing double kfree as all callers of smi_add does a kfree on error.

It is incorrect to call pci_restore_state() for devices in low-power states (D1-D3), as that involves the restoration of MSI setup which requires MMIO to be operational and that is only the case in D0. However, pci_pm_thaw_noirq() may do that if the driver's "freeze" callbacks put the device into a low-power state, so fix it by making it force devices into D0 via pci_set_power_state() instead of trying to "update" their power state which is pointless.
