This patch restructures the existing adxl372 driver by adding a module for

Add support for processing switch jump tables in objects with multiple
.rodata sections, such as those created by '-ffunction-sections' and
'-fdata-sections'. Currently, objtool always looks in .rodata for jump
table information, which results in many "sibling call from callable
instruction with modified stack frame" warnings with objects compiled
using those flags.
The fix is comprised of three parts:
1. Flagging all .rodata sections when importing ELF information for
easier checking later.
2. Keeping a reference to the section each relocation is from in order
to get the list_head for the other relocations in that section.
3. Finding jump tables by following relocations to .rodata sections,
rather than always referencing a single global .rodata section.
The patch has been tested without data sections enabled and no
differences in the resulting orc unwind information were seen.
Note that as objtool adds terminators to end of each .text section the
unwind information generated between a function+data sections build and
a normal build aren't directly comparable. Manual inspection suggests
that objtool is now generating the correct information, or at least
making more of an effort to do so than it did previously.

When page-table entries are set, the compiler might optimize their
assignment by using multiple instructions to set the PTE. This might
turn into a security hazard if the user somehow manages to use the
interim PTE. L1TF does not make our lives easier, making even an interim
non-present PTE a security hazard.
Using WRITE_ONCE() to set PTEs and friends should prevent this potential
security hazard.
I skimmed the differences in the binary with and without this patch. The
differences are (obviously) greater when CONFIG_PARAVIRT=n as more
code optimizations are possible. For better and worse, the impact on the
binary with this patch is pretty small. Skimming the code did not cause
anything to jump out as a security hazard, but it seems that at least
move_soft_dirty_pte() caused set_pte_at() to use multiple writes.

In the non-trampoline SYSCALL64 path, a percpu variable is used to

Instead of a separate variable, use the otherwise unused sp2 slot in the

the same code to find the kernel stack. It will also simplify a future

Instead of introducing a new wait queue rename the existing

unloading).
As any state change of the backend might be intended to stop waiting
do the wake_up_all() in any case when netback_changed() is called.

Fix the cell specification mechanism to allow cells to be pre-created
without having to specify at least one address (the addresses will be
upcalled for).
This allows the cell information preload service to avoid the need to issue
loads of DNS lookups during boot to get the addresses for each cell (500+
lookups for the 'standard' cell list[*]). The lookups can be done later as
each cell is accessed through the filesystem.
Also remove the print statement that prints a line every time a new cell is
added.
[*] There are 144 cells in the list. Each cell is first looked up for an
SRV record, and if that fails, for an AFSDB record. These get a list
of server names, each of which then has to be looked up to get the
addresses for that server. E.g.:

Commit 3559d81e76 ("r8169: simplify rtl_hw_start_8169") changed order of
two register writes:
1) Caused RxConfig to be written before TX / RX is enabled,
2) Caused TxConfig to be written before TX / RX is enabled.
At least on XIDs 10000000 ("RTL8169sb/8110sb") and
18000000 ("RTL8169sc/8110sc") such writes are ignored by the chip, leaving
values in these registers intact.
Change 1) was reverted by
commit 05212ba813 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices"),
however change 2) wasn't.
In practice, this caused TxConfig's "InterFrameGap time" and "Max DMA Burst
Size per Tx DMA Burst" bits to be zero dramatically reducing TX performance
(in my tests it dropped from around 500Mbps to around 50Mbps).
This patch fixes the issue by moving TxConfig register write a bit later in
the code so it happens after TX / RX is already enabled.

Pull arm64 fix from Will Deacon:
"Just one small fix here, preventing a VM_WARN_ON when a !present
PMD/PUD is "freed" as part of a huge ioremap() operation.
The correct behaviour is to skip the free silently in this case, which
is a little weird (the function is a bit of a misnomer), but it
follows the x86 implementation"
