2021-05-31clk: tegra: Don't deassert reset on enabling clocksDmitry Osipenko3-13/+1
The Tegra clock driver contains legacy code which deasserts hardware reset when peripheral clocks are enabled. This behaviour comes from a pre-CCF era of the Tegra drivers. This is unacceptable for modern kernel drivers which use generic CCF and reset-control APIs because it breaks assumptions of the drivers about clk/reset sequences and about reset-propagation delays. Hence remove the awkward legacy behaviour from the clk driver. In particular PMC driver assumes that hardware blocks remains in reset while power domain is turning on, but the clk driver deasserts the reset before power clamp is removed, hence breaking the driver's assumption.

2021-05-31clk: tegra: Don't allow zero clock rate for PLLsDmitry Osipenko1-0/+3
Zero clock rate doesn't make sense for PLLs and tegra-clk driver enters into infinite loop on trying to calculate PLL parameters for zero rate. Make code to error out if requested rate is zero. Originally this trouble was found by Robert Yang while he was trying to bring up upstream kernel on Samsung Galaxy Tab, which happened due to a bug in Tegra DRM driver that erroneously sets PLL rate to zero. This issues came over again recently during of kernel bring up on ASUS TF700T. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-05-31clk: tegra: Halve SCLK rate on Tegra20Dmitry Osipenko1-3/+3
Higher SCLK rates on Tegra20 require high core voltage. The higher clock rate may have a positive performance effect only for AHB DMA transfers and AVP CPU, but both aren't used by upstream kernel at all. Halve SCLK rate on Tegra20 in order to remove the high core voltage requirement.

2021-05-31clk: tegra: Ensure that PLLU configuration is applied properlyDmitry Osipenko1-5/+4
The PLLU (USB) consists of the PLL configuration itself and configuration of the PLLU outputs. The PLLU programming is inconsistent on T30 vs T114, where T114 immediately bails out if PLLU is enabled and T30 re-enables a potentially already enabled PLL (left after bootloader) and then fully reprograms it, which could be unsafe to do. The correct way should be to skip enabling of the PLL if it's already enabled and then apply configuration to the outputs. This patch doesn't fix any known problems, it's a minor improvement.

2021-05-31clk: tegra: Fix refcounting of gate clocksDmitry Osipenko2-25/+58
The refcounting of the gate clocks has a bug causing the enable_refcnt to underflow when unused clocks are disabled. This happens because clk provider erroneously bumps the refcount if clock is enabled at a boot time, which it shouldn't be doing, and it does this only for the gate clocks, while peripheral clocks are using the same gate ops and the peripheral clocks are missing the initial bump. Hence the refcount of the peripheral clocks is 0 when unused clocks are disabled and then the counter is decremented further by the gate ops, causing the integer underflow. Fix this problem by removing the erroneous bump and by implementing the disable_unused() callback, which disables the unused gates properly. The visible effect of the bug is such that the unused clocks are never gated if a loaded kernel module grabs the unused clocks and starts to use them. In practice this shouldn't cause any real problems for the drivers and boards supported by the kernel today.

Commit b9d79e4ca4ff ("fbmem: Mark proc_fb_seq_ops as __maybe_unused") places the '__maybe_unused' in an entirely incorrect location between the "struct" keyword and the structure name.

There's the removal of the nvlink code, which dependend on a commit in the vfio tree. Then the enablement of huge vmalloc which was in next for a few weeks but got dropped due to conflicts. And there's also a few fixes. Summary: - Remove the nvlink support now that it's only user has been removed. - Enable huge vmalloc mappings for Radix MMU (P9). - Fix KVM conversion to gfn-based MMU notifier callbacks. - Fix a kexec/kdump crash with hot plugged CPUs. - Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR. - Restore alphabetic order of the selects under CONFIG_PPC.

2021-05-08smb3: when mounting with multichannel include it in requested capabilitiesSteve French1-0/+5
In the SMB3/SMB3.1.1 negotiate protocol request, we are supposed to advertise CAP_MULTICHANNEL capability when establishing multiple channels has been requested by the user doing the mount. See MS-SMB2 sections 2.2.3 and 3.2.5.2 Without setting it there is some risk that multichannel could fail if the server interpreted the field strictly.

2021-05-09linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>Masahiro Yamada3-6/+5
<linux/kconfig.h> is included from all the kernel-space source files, including C, assembly, linker scripts. It is intended to contain a minimal set of macros to evaluate CONFIG options. IF_ENABLED() is an intruder here because (x ? y : z) is C code, which should not be included from assembly files or linker scripts. Also, <linux/kconfig.h> is no longer self-contained because NULL is defined in <linux/stddef.h>. Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF() takes the general boolean expression instead of a CONFIG option so that it fits better in <linux/kernel.h>.

Merge master back into next, this allows us to resolve some conflicts in arch/powerpc/Kconfig, and also re-sort the symbols under config PPC so that they are in alphabetical order again.

2021-05-07net: stmmac: Do not enable RX FIFO overflow interruptsYannick Vignon2-18/+3
The RX FIFO overflows when the system is not able to process all received packets and they start accumulating (first in the DMA queue in memory, then in the FIFO). An interrupt is then raised for each overflowing packet and handled in stmmac_interrupt(). This is counter-productive, since it brings the system (or more likely, one CPU core) to its knees to process the FIFO overflow interrupts. stmmac_interrupt() handles overflow interrupts by writing the rx tail ptr into the corresponding hardware register (according to the MAC spec, this has the effect of restarting the MAC DMA). However, without freeing any rx descriptors, the DMA stops right away, and another overflow interrupt is raised as the FIFO overflows again. Since the DMA is already restarted at the end of stmmac_rx_refill() after freeing descriptors, disabling FIFO overflow interrupts and the corresponding handling code has no side effect, and eliminates the interrupt storm when the RX FIFO overflows.

2021-05-07mptcp: fix splat when closing unaccepted socketPaolo Abeni1-2/+1
If userspace exits before calling accept() on a listener that had at least one new connection ready, we get: Attempt to release TCP socket in state 8 This happens because the mptcp socket gets cloned when the TCP connection is ready, but the socket is never exposed to userspace. The client additionally sends a DATA_FIN, which brings connection into CLOSE_WAIT state. This in turn prevents the orphan+state reset fixup in mptcp_sock_destruct() from doing its job.
