[ Upstream commit b91676fc16 ]
Currently, the memremap() called with MEMREMAP_WB maps memory using
the generic ioremap() function which breaks on system with Svpbmt
because memory mapped using _PAGE_IOREMAP page attributes is treated
as strongly-ordered non-cacheable IO memory.
To address this, we implement RISC-V specific arch_memremap_wb()
which maps memory using _PAGE_KERNEL page attributes resulting in
write-back cacheable mapping on systems with Svpbmt.

[ Upstream commit b0f4c74ead ]
The return to userspace path in entry.S may enable interrupts without the
corresponding lockdep annotation, producing a splat[0] when DEBUG_LOCKDEP
is enabled. Simply calling __trace_hardirqs_on() here gets a bit messy
due to the use of RA to point back to ret_from_exception, so just move
the whole slow-path loop into C. It's more readable and it lets us use
local_irq_{enable,disable}(), avoiding the need for manual annotations
altogether.

[ Upstream commit 487d65090a ]
After the hns roce driver is loaded, if you modify the mac address of the
network port, the following error will appear:
__ib_cache_gid_add: unable to add gid fe80:0000:0000:0000:4600:4dff:fe22:abb5 error=-28
hns3 0000:7d:00.0 hns_0: attr path_mtu(1) invalid while modify qp
The reason for the error is that the gid being occupied will cause the
failure to modify the gid. The gid is occupied by the loopback QP used by
free mr. When the mac address is modified, the gid will change. If there
is a busy QP at this time, the gid will not be released and the
modification will fail. The QP of free mr is created using the ib
interface. The ib interface will add a reference count to the gid,
resulting in this error scenario.
Considering that free mr is solving a bug in HIP08, not an actual
business, it is not necessary to use ib interfaces.

[ Upstream commit 0a584655ef ]
The reset was never applied in the current implementation because Intel
Bridges owned by VMD are parentless. Internally, pci_reset_bus() applies
a reset to the parent of the PCI device supplied as argument, but in this
case it failed because there wasn't a parent.
In more detail, this change allows the VMD driver to enumerate NVMe devices
in pass-through configurations when guest reboots are performed. There was
an attempted to fix this, but later we discovered that the code inside
pci_reset_bus() wasn’t triggering secondary bus resets. Therefore, we
updated the parameters passed to it, and now NVMe SSDs attached to VMD
bridges are properly enumerated in VT-d pass-through scenarios.

Otherwise, the code crashes with a CFI failure.
(Or at least that should be the case. For some reason the CFI checks in
sm4_avx_cbc_decrypt(), sm4_avx_cfb_decrypt(), and sm4_avx_ctr_crypt()
are not always being generated, using current tip-of-tree clang.
Anyway, this patch is a good idea anyway.)

sm3_transform_avx() is called via indirect function calls. Therefore it
needs to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause its
type hash to be emitted when the kernel is built with
CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure (if
the compiler didn't happen to optimize out the indirect call).

list_for_each_entry_reverse() assumes that the iterated list is nonempty
and that every list_head is embedded in the same type, but its use in
padata_do_serial() breaks both rules.
This doesn't cause any issues now because padata_priv and padata_list
happen to have their list fields at the same offset, but we really
shouldn't be relying on that.

[ Upstream commit 34c3a47d20 ]
A deadlock can happen when an overloaded system runs ->parallel() in the
context of the current task:
padata_do_parallel
->parallel()
pcrypt_aead_enc/dec
padata_do_serial
spin_lock(&reorder->lock) // BHs still enabled
<interrupt>
...
__do_softirq
...
padata_do_serial
spin_lock(&reorder->lock)
It's a bug for BHs to be on in _do_serial as Steffen points out, so
ensure they're off in the "current task" case like they are in
padata_parallel_worker to avoid this situation.

In the past, the data for mb-skcipher test has been allocated
twice, that means the first allcated memory area is without
free, which may cause a potential memory leakage. So this
patch is to remove one allocation to fix this error.
