According to ECMA-130 standard maximum valid track number is 99. Since
'session' mount option starts indexing at 0 (and we add 1 to the passed
number), we should refuse value 99. Also the condition in
isofs_get_last_session() unnecessarily repeats the check - remove it.

Currently even with STRICT_KERNEL_RWX we leave the __init text marked
executable after init, which is bad.
Add a hook to mark it NX (no-execute) before we free it, and implement
it for radix and hash.
Note that we use __init_end as the end address, not _einittext,
because overlaps_kernel_text() uses __init_end, because there are
additional executable sections other than .init.text between
__init_begin and __init_end.
Tested on radix and hash with:
0:mon> p $__init_begin

When changing a file's acl mask, reiserfs_set_acl() will first set the
group bits of i_mode to the value of the mask, and only then set the
actual extended attribute representing the new acl.
If the second part fails (due to lack of space, for example) and the
file had no acl attribute to begin with, the system will from now on
assume that the mask permission bits are actual group permission bits,
potentially granting access to the wrong users.
Prevent this by only changing the inode mode after the acl has been set.

Move the core logic into a helper, so we can use it for changing other
permissions.
We also change the logic to align start down, and end up. This means
calling the function with a range will expand that range to be at
least 1 mmu_linear_psize page in size. We need that so we can use it
on __init_begin ... __init_end which is not a full page in size.
This should always work for _stext/__init_begin, because we align
__init_begin to _stext + 16M in the linker script.

Since commit d59f6617ee ("genirq: Allow fwnode to carry name
information only") the irqdomain core sets the names of irq domains.
When the name is allocated the new IRQ_DOMAIN_NAME_ALLOCATED flag is
set. Replacing the allocated name with a constant one is not a good
idea, since calling the new irq_domain_update_bus_token() API, added to
the MIPS GIC driver by commit 96f0d93a48 ("irqchip/MSI: Use
irq_domain_update_bus_token instead of an open coded access") will
attempt to kfree the pointer, and result in a kernel OOPS.
Fix this by removing the names, now that they are set by the irqdomain
core. This effectively reverts commit 21c57fd135 ("irqchip/mips-gic:

This patch makes use of functions added in the previous patch. It
registers ldisc during init of main speakup module and unregisters it
during exit. It also removes the code to register ldisc every time a
synth module is loaded. This way we only register the ldisc once when
main speakup module is loaded. Since main speakup module is required by
all synth modules, it is only unloaded when all synths have been
unloaded. Therefore we unregister the ldisc once, when all speakup
related references to the ldisc have returned. In unlikely scenario of
something outside speakup using the ldisc, the ldisc refcount check in
tty_unregister_ldisc will ensure that it is not unregistered while in
use.
The function to register ldisc doesn't cause speakup init function to
fail. That is different from current behaviour where failure to register
ldisc results in failure to load the specific synth module. This is
because speakup module is also required by those synths which don't use
tty and ldisc. We don't want to prevent those modules from loading when
ldisc fails to register. The synth modules will correctly fail when
trying to set N_SPEAKUP to tty, if ldisc registrationi had failed.

Speakup opens tty using tty_open_by_driver. When closing, it calls
tty_ldisc_release but doesn't close and remove the tty itself. As a
result, that tty cannot be opened from user space. This patch calls
tty_release_struct which ensures that tty is safely removed and freed
up. It also calls tty_ldisc_release, so speakup doesn't need to call it.

The ib_wq isn't an ordered workqueue and thus two work elements can be executed
concurrently which will result in unexpected behavior and inconsistency of the
GIDs cache content.
Example:
ifconfig eth1 11.11.11.11/16 up
This command will invoke the following netdev events in the following order:
1. NETDEV_UP
2. NETDEV_DOWN
3. NETDEV_UP
If (2) and (3) will be executed concurrently or in reverse order, instead of

Commit 21caf2fc19 ("mm: teach mm by current context info to not do I/O

to enable people to modify the MM behavior by disabling I/O during memory
allocation. This was further extended in Fixes: 934f3072c1 ("mm: clear
__GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent
allocation paths recursing back into the filesystem without explicitly
changing the flags for every allocation site.
However the IPoIB hasn't been keeping up with the changes and missed
completely these memalloc_noio_* calls. This led to update of
allocation site with special QP creation flag, see commit 09b93088d7
("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this
flag is supported by small number of drivers in IB stack.
Let's change it by updating to memalloc_noio_* calls and allow

Interrupts with the IRQF_FORCE_RESUME flag set have also the
IRQF_NO_SUSPEND flag set. They are not disabled in the suspend path, but
must be forcefully resumed. That's used by XEN to keep IPIs enabled beyond
the suspension of device irqs. Force resume works by pretending that the
interrupt was disabled and then calling __irq_enable().
Incrementing the disabled depth counter was enough to do that, but with the
recent changes which use state flags to avoid unnecessary hardware access,
this is not longer sufficient. If the state flags are not set, then the
hardware callbacks are not invoked and the interrupt line stays disabled in
"hardware".
Set the disabled and masked state when pretending that an interrupt got
disabled by suspend.

Pull regmap fix from Mark Brown:
"Fix build due to w1 header refactoring
The regmap support for w1 was added shortly before a reorganization of
the w1 headers. While this was noticed before the merge window and
efforts made to get it resolved in what was sent that managed to fall
through the cracks, this cleans up and updates things so we look for
the header in the new location.
It didn't cause build failures as the driver that's going to be the
first user got held up with other review issues"

regmap: regmap-w1: Fix build troubles
This is actually just a small set of mainly bug fixes for the original
merge window code plus a few trivial updates and qedi boot from SAN
support feature patch.
