Previously, f2fs_checkpoint.checksum_offset points fixed position of
f2fs_checkpoint structure:
"#define CP_CHKSUM_OFFSET 4092"
It is unnecessary, and it breaks the consecutiveness of nat and sit
bitmap stored across checkpoint park block and payload blocks.
This patch allows f2fs to handle unfixed .checksum_offset.
In addition, for the case checksum value is stored in the middle of
checkpoint park, calculating checksum value with superposition method
like we did for inode_checksum.

This patch expands scalability of dnode layout, it allows address pointer
number of dnode aligning to specified size (now, the size is one byte by
default), and later the number can align to compress cluster size
(1 << n bytes, n=[2,..)), it can avoid cluster acrossing two dnode, making
design of compress meta layout simple.

This patch introduces f2fs_read_single_page() to wrap core operations
of reading one page in f2fs_mpage_readpages().
In addition, if we failed in f2fs_mpage_readpages(), propagate error
number to f2fs_read_data_page(), for f2fs_read_data_pages() path,
always return success.

sit.vblocks and sum valid block count in sit.valid_map may be
inconsistent, segment w/ zero vblocks will be treated as free
segment, while allocating in free segment, we may allocate a
free block, if its bitmap is valid previously, it can cause
kernel crash due to bitmap verification failure.
Anyway, to avoid further serious metadata inconsistence and

vblocks and valid_map all the time rather than do it only

On below paths, we can have opportunity to readahead inode page
- gc_node_segment -> f2fs_ra_node_page
- gc_data_segment -> f2fs_ra_node_page
- f2fs_fill_dentries -> f2fs_ra_node_page
Unlike synchronized read, on readahead path, we can set page uptodate
before verifying page's checksum, then read_node_page() will trigger
kernel panic once it encounters a uptodated page w/ incorrect checksum.
So considering readahead scenario, we have to do checksum each time
when loading inode page even if it is uptodated.

With below mkfs and mount option:

MOUNT_OPTIONS -- -o noinline_xattr
We may miss xattr data with below testcase:

- setfattr -n "user.name" -v 0 dir
- for ((i = 0; i < 190; i++)) do touch dir/$i; done
- umount
- mount
- getfattr -n "user.name" dir
user.name: No such attribute
The root cause is that we persist xattr data into reserved inline xattr
space, even if inline_xattr is not enable in inline directory inode, after
inline dentry conversion, reserved space no longer exists, so that xattr
data missed.
Let's use inline xattr space only if inline_xattr flag is set on inode

level:8, dir_level:0, pgofs:951, correct range:[900, 901]
In old kernel, inline data and directory always reserved 200 bytes in
inode layout, even if inline_xattr is disabled, then new kernel tries
to retrieve that space for non-inline xattr inode, but for inline dentry,
its layout size should be fixed, so we just keep that reserved space.
But the problem here is that, after inline dentry conversion, inline
dentry layout no longer exists, if we still reserve inline xattr space,
after dents updates, there will be a hole in inline xattr space, which
can break hierarchy hash directory structure.
This patch fixes this issue by retrieving inline xattr space after
inline dentry conversion.

During GC, if segment type stored in SSA and SIT is inconsistent, we just
skip migrating current segment directly, since we need to know the exact
type to decide the migration function we use.
So in foreground GC, we will easily run into a infinite loop as we may
select the same victim segment which has inconsistent type due to greedy
policy. In order to end up this, we choose to shutdown filesystem. For
backgrond GC, we need to do that as well, so that we can avoid latter
potential infinite looped foreground GC.

It doesn't seem to make much sense to convert this one

v4.20.
- Our eBPF JIT the previously supported only MIPS64r2 through MIPS64r5
is improved to also support MIPS64r6. Support for MIPS32 systems is
introduced, with the caveat that it only works for programs that
don't use 64 bit registers or operations - those will bail out & need
to be interpreted.
- Improvements to the allocation & configuration of our exception
vector that should fix issues seen on some platforms using recent
versions of U-Boot.
- Some minor improvements to code generated for jump labels, along with
enabling them by default for generic kernels.

====================
net: phy: realtek: Fix RGMII TX/RX-delays initial config of rtl8211(e|f)
It has been discovered that RX/TX delays of rtl8211e ethernet PHY
can be configured via a MDIO register hidden in the extension pages
layout. Particularly the extension page 0xa4 provides a register 0x1c,
which bits 1 and 2 control the described delays. They are used to
implement the "rgmii-{id,rxid,txid}" phy-mode support in patch 1.
The second patch makes sure the rtl8211f TX-delay is configured only
if RGMII interface mode is specified including the rgmii-rxid one.
In other cases (most importantly for NA mode) the delays are supposed
to be preconfigured by some other software or hardware and should be
left as is without any modification. The similar thing is also done
for rtl8211e in the patch 1 of this series.
Changelog v3
- Add this cover-letter.
- Add Andrew' Reviewed-by tag to patch 1.
- Accept RGMII_RXID interface mode for rtl8211f and clear the TX_DELAY
bit in this case.
- Initialize ret variable with 0 to prevent the "may be used uninitialized"
warning in patch 1.
Changelog v4
- Rebase onto net-next

It's prone to problems if delay is cleared out for other than RGMII

There are two chip pins named TXDLY and RXDLY which actually adds the 2ns
delays to TXC and RXC for TXD/RXD latching. Alas this is the only
documented info regarding the RGMII timing control configurations the PHY
provides. It turns out the same settings can be setup via MDIO registers
hidden in the extension pages layout. Particularly the extension page 0xa4
provides a register 0x1c, which bits 1 and 2 control the described delays.
They are used to implement the "rgmii-{id,rxid,txid}" phy-mode.
The hidden RGMII configs register utilization was found in the rtl8211e
U-boot driver:
https://elixir.bootlin.com/u-boot/v2019.01/source/drivers/net/phy/realtek.c#L99
There is also a freebsd-folks discussion regarding this register:
https://reviews.freebsd.org/D13591
It confirms that the register bits field must control the so called
configuration pins described in the table 12-13 of the official PHY
datasheet:
8:6 = PHY Address
5:4 = Auto-Negotiation
3 = Interface Mode Select
2 = RX Delay
1 = TX Delay
0 = SELRGV

Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.
The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.
Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

When the ideapad-laptop driver was first written it was written for laptops
which had a hardware rfkill switch. So when the first ideapad laptops
showed up without a hw rfkill switch and it turned out that in this case
the ideapad firmware interface would always report the wifi being hardware-
blocked, a DMI id list of models which lack a hw rfkill switch was started
(by yours truly). Things were done this way to avoid regressing existing
models with a hw rfkill switch. In hindsight this was a mistake.
Lenovo releases a lot of ideapad models every year and even the latest
models still use the "VPC2004" ACPI interface the ideapad-laptop driver
binds to. Having a hw rfkill switch is quite rare on modern hardware, so
all these new models need to be added to the no_hw_rfkill_list, leading
to a never ending game of whack a mole.
Worse the failure mode when not present on the list, is very bad. In this
case the ideapad-laptop driver will report the wifi as being hw-blocked,
at which points NetworkManager does not even try to use it and the user
ends up with non working wifi.
This leads to various Linux fora on the internet being filled with
wifi not working on ideapad laptops stories, which does not make Linux
look good.
The failure mode when we flip the default to assuming that a hw rfkill
switch is not present OTOH is quite benign. When we properly report the
wifi as being hw-blocked on ideapads which do have the hw-switch; and it
is in the wifi-off position, then at least when using NetworkManager +
GNOME3 the user will get a "wifi disabled in hardware" message when trying
to connect to the wifi from the UI. If OTOH we assume there is no hardware
rfkill switch, then the user will get an empty list for the list of
available networks. Although the empty list vs the "wifi disabled in
hardware" message is a regression, it is a very minor regression and it
can easily be fixed on a model by model basis by filling the new
hw_rfkill_list this commit introduces.
Therefor this commit removes the ever growing no_hw_rfkill_list, flipping
the default to assuming there is no hw rfkill switch and adding a new
hw_rfkill_list. Thereby fixing the wifi not working on all the current
ideapad and yoga models which are not on the list yet and also fixing it
for all future ideapad and yoga models using the "VPC2004" ACPI interface.
Note once this patch has been accepted upstream. I plan to write a blog
post asking for users of ideapads and yoga's with a hw rfkill switch to
step forward, so that we can populate the new hw_rfkill_list with the few
older yoga and ideapad models which actually have a hw rfkill switch.
