Hello,

This patch allows to use all PHYs on GRX300 and GRX330. The ARX300
has 3 and the GRX330 has 4 integrated PHYs connected to different
ports compared to VRX200. Each integrated PHY can work as single
Gigabit Ethernet PHY (GMII) or as double Fast Ethernet PHY (MII).
Allowed port configurations:
Add compatible string for xRX300 and xRX330 SoCs.

Here are two known problems with registers when a tracee is stopped in

The first problem is about the x7 register that is used to indicate
whether or not the stop has been signalled from syscall entry or syscall
exit. This means that:
- Any writes by the tracer to this register
We have some ABI weirdness in the way that we handle syscall exit stops
because we indicate whether or not the stop has been signalled from
syscall entry or syscall exit by clobbering a general purpose register
x7 in the tracee and restoring its old value after the stop.
This behavior was
The test creates two processes where one traces another one. The tracee
executes a system call, the tracer traps it, changes orig_x0, triggers a
signal and checks that the syscall is restarted with the setted

Test output:

In system calls, x7 is used to indicate whether a tracee has been
stopped on syscall-enter or syscall-exit and the origin value of x7 is
saved in orig_x7.

If we're trying to allocate 4MB of memory, the table will be 8KiB in size
(1024 pointers * 8 bytes per pointer), which can usually be satisfied
by a kmalloc (which is significantly faster). Instead of changing this
open-coded implementation, just use kvmalloc().

This fix is analogous to Peter Xu's fix for hugetlb [0]. If we don't
put_page() after getting the page out of the page cache, we leak the

The fix can be verified by checking /proc/meminfo and running the

v4:
- Fixed a few "subordinate clauses" (SC) cases [Alex]
- Reword in ioctl_userfaultfd.2 to use bold font for the two modes referenced,
so as to be clear on what is "both" referring to [Alex]
v3:
- Don't use "Currently", instead add "(since x.y)" mark where proper [Alex]
- Always use semantic
Userfaultfd write-protect mode is supported starting from Linux 5.7.

gcc warns about a couple of instances in which a sanity check
exists but the author wasn't sure how to react to it failing,
which makes it look like a possible bug:
fs/hfsplus/inode.c: In function 'hfsplus_cat_read_inode':
fs/hfsplus/inode.c:503:37: error: suggest braces

Hi Paul,
Was working on automation to make it a bit more straightforward to fix
typos within comments (which we tend to reintroduce during
development), and here are the ones it found in the RCU code.
Thanks,
Ingo

Have you found any other driver doing this? Where do they

Note that the special uffd-wp swap pte can be left over even if the page under
the pte got evicted. Normally when evict a page, we will unmap the ptes by
walking through the reverse mapping. However we never tracked such information
for the special swap ptes because they're not real mappings but
Hook up hugetlbfs_fault() with the capability to handle userfaultfd-wp faults.
We do this slightly earlier than hugetlb_cow() so that we can avoid taking some
extra locks that we definitely don't need.

This is to let hugetlbfs be prepared to also recognize swap special ptes just
like uffd-wp special swap ptes.

Jan,
Why does ext2_set_link() need to call ext2_put_page()?
I don't see any reason that we could not match up the ext2_put_page() calls
with the ext2_find_entry().
Similarly am I missing something by moving the ext2_put_page() out of
ext2_delete_entry()?
See below patch.
I'm in the process of
