There are no callers for the functions which will pass unaligned physical
addresses. Hence just change these BUG_ON() checks into VM_BUG_ON() which
gets compiled out unless CONFIG_VM_DEBUG is enabled.

The `resource` in do_prlimit() is controlled by userspace via syscall:
setrlimit(defined in kernel/sys.c), hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
The relevant code in do_prlimit() is as below：
if (resource >= RLIM_NLIMITS)
return -EINVAL;

This patch series enables hardware offload for flower filter used in

The patch series is based on:
commit 6ab1f192dcb4 ("net: mscc: ocelot: Implement port policers via tc
command")
CC: Alexandre Belloni
CC: Microchip Linux Driver Support

Add ACL support using the TCAM. Using ACL it is possible to create rules

total_swapcache_pages() may race with swapper_spaces[] allocation and
freeing. Previously, this is protected with a swapper_spaces[]
specific RCU mechanism. To simplify the logic/code complexity, it is
replaced with get/put_swap_device(). The code line number is reduced
too.

Some in-kernel headers use _BITUL() instead of BIT().

I think the reason is because BIT() is currently not available

However, low-level code is often written in assembly, where they are

Add edma2 for i.mx7ulp by version v3, since v2 has already
been used by mcf-edma.
The big changes based on v1 are belows:
1. only one dmamux.
2. another clock dma_clk except dmamux clk.
3. 16 independent interrupts instead of only one interrupt for
all channels.

Quoting Paul [1]:
"Given that a quick (and perhaps error-prone) search of the uses
of rcu_assign_pointer() in v5.1 didn't find a single use of the
return value, let's please instead change the documentation and
implementation to eliminate the return value."

Hi!
So if you compile a kernel, then reboot, boot will hang after "Freeing SMP
alternatives memory" (and then wastes power, making thermal situation even
worse).
Unfortunately, threshold for non-booting system is quite low, fan does _not_
go full speed after reboot. Annoying for kernel developme
