f4f31fff32 Power management updates for 5.0-rc2
- Prevent integer overflows from occurring on 32-bit when
    converting milliseconds to nanoseconds in the runtime PM
    framework and update comments that still refer to jiffies
    in it (Vincent Guittot, Ladislav Michl).
 
  - Fix the SCMI cpufreq driver to always use the same frequency
    units for arch_set_freq_scale() and make the scale-invariant
    load tracking acutally work with this driver (Quentin Perret).
 
  - Fix freeing of dynamic OPPs in the SCPI and SCMI cpufreq drivers
    broken during the 4.20 defelopment cycle (Viresh Kumar).
 
  - Prevent the cpufreq core from attempting to return the current
    frequency of offline CPUs (Sudeep Holla).
 
  - Add devfreq suspend and resume hooks (missed previously) to the
    PM core to make the recently added system suspend and resume
    support in devfreq actually work (Lukasz Luba).
 
  - Update MAINTAINERS entries for cpufreq and cpuidle, mostly to add
    references to new/current documentation to them (Rafael Wysocki).
 
  - Fix a recently broken reference to cpuidle documentation (Otto
    Sabart).

d3736d82e8 tty: Don't hold ldisc lock in tty_reopen() if ldisc present
Try to get reference for ldisc during tty_reopen().
If ldisc present, we don't need to do tty_ldisc_reinit() and lock the
write side for line discipline semaphore.
Effectively, it optimizes fast-path for tty_reopen(), but more
importantly it won't interrupt ongoing IO on the tty as no ldisc change
is needed.
Fixes user-visible issue when tty_reopen() interrupted login process for
user with a long password, observed and reported by Lukas.

e3e4767bd5 mmc: core: don't override the CD GPIO level when "cd-inverted" is set
Since commit 89a5e15bcb ("gpio/mmc/of: Respect polarity in the device
tree") gpiolib-of parses the "cd-gpios" property and flips the polarity
if "cd-inverted" is also set. This results in the "cd-inverted" property
being evaluated twice, which effectively makes it a no-op:
- first in drivers/gpio/gpiolib-of.c (of_xlate_and_get_gpiod_flags) when
  setting up the CD GPIO
- then again in drivers/mmc/core/slot-gpio.c (mmc_gpio_get_cd) when
  reading the CD GPIO value at runtime

On boards which are using device-tree with the "cd-inverted" property
being set any inserted card are not detected anymore. This is due to the
MMC core treating the CD GPIO with the wrong polarity.

Disable "override_cd_active_level" for the card detection GPIO which is
parsed using mmc_of_parse. This fixes SD card detection on the boards
which are currently using the "cd-inverted" device-tree property (tested
on Meson8b Odroid-C1 and Meson8b EC-100).

This does not remove the CD GPIO inversion logic from the MMC core
because there's at least one driver (sdhci-pci-core for Intel BayTrail
based boards) which still passes "override_cd_active_level = true" to
mmc_gpiod_request_cd(). Due to lack of hardware for testing this is left
untouched.
In the future the GPIO inversion logic for both, card and read-only
detection can be removed once no driver is using it anymore.

ee258d7915 CIFS: Move credit processing to mid callbacks for SMB3
Currently we account for credits in the thread initiating a request
and waiting for a response. The demultiplex thread receives the response,
wakes up the thread and the latter collects credits from the response
buffer and add them to the server structure on the client. This approach
is not accurate, because it may race with reconnect events in the
demultiplex thread which resets the number of credits.

Fix this by moving credit processing to new mid callbacks that collect
credits granted by the server from the response in the demultiplex thread.

8a26f0f781 CIFS: Fix credits calculation for cancelled requests
If a request is cancelled, we can't assume that the server returns
1 credit back. Instead we need to wait for a response and process
the number of credits granted by the server.

Create a separate mid callback for cancelled request, parse the number
of credits in a response buffer and add them to the client's credits.
If the didn't get a response (no response buffer available) assume
0 credits granted. The latter most probably happens together with
session reconnect, so the client's credits are adjusted anyway.

92a8109e4d cifs: Limit memory used by lock request calls to a page
The code tries to allocate a contiguous buffer with a size supplied by
the server (maxBuf). This could fail if memory is fragmented since it
results in high order allocations for commonly used server
implementations. It is also wasteful since there are probably
few locks in the usual case. Limit the buffer to be no larger than a
page to avoid memory allocation failures due to fragmentation.

21face6f0d ARM: integrator: impd1: use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

====================
The previous BTF kind_flag support patch set introduced a bug
for kernel bpffs pretty printing and another bug for bpftool
map pretty printing. If a bitfield struct member offset is
greater than 256 bits, printed value for that struct
member will be incorrect.

- Patch #1 fixed the bug in kernel bpffs pretty printing.
- Patch #2 enhanced the test_btf test case to cover the
           issue exposed by patch #1.
- Patch #3 fixed the bug in bpftool map pretty printing.

298e59d322 tools/bpf: fix bpftool map dump with bitfields
Commit 8772c8bc09 ("tools: bpftool: support pretty print
with kind_flag set") added bpftool map dump with kind_flag
support. When bitfield_size can be retrieved directly from
btf_member, function btf_dumper_bitfield() is called to
dump the bitfield. The implementation passed the
wrong parameter "bit_offset" to the function. The excepted
value is the bit_offset within a byte while the passed-in
value is the struct member offset.

This commit fixed the bug with passing correct "bit_offset"
with adjusted data pointer.

17e3ac8125 bpf: fix bpffs bitfield pretty print
Commit 9d5f9f701b ("bpf: btf: fix struct/union/fwd types
with kind_flag") introduced kind_flag and used bitfield_size
in the btf_member to directly pretty print member values.

The commit contained a bug where the incorrect parameters could be
passed to function btf_bitfield_seq_show(). The bits_offset
parameter in the function expects a value less than 8.
Instead, the member offset in the structure is passed.

The below is btf_bitfield_seq_show() func signature:
  void btf_bitfield_seq_show(void *data, u8 bits_offset,
                             u8 nr_bits, struct seq_file *m)
both bits_offset and nr_bits are u8 type. If the bitfield
member offset is greater than 256, incorrect value will
be printed.

This patch fixed the issue by calculating correct proper
data offset and bits_offset similar to non kind_flag case.

6ebec961d5 i2c: dev: prevent adapter retries and timeout being set as minus value
If adapter->retries is set to a minus value from user space via ioctl,
it will make __i2c_transfer and __i2c_smbus_xfer skip the calling to
adapter->algo->master_xfer and adapter->algo->smbus_xfer that is
registered by the underlying bus drivers, and return value 0 to all the
callers. The bus driver will never be accessed anymore by all users,
besides, the users may still get successful return value without any
error or information log print out.

If adapter->timeout is set to minus value from user space via ioctl,
it will make the retrying loop in __i2c_transfer and __i2c_smbus_xfer
always break after the the first try, due to the time_after always
returns true.

maybe other boards using this generic driver are affected

v2:
optimization:

- phy_set_max_speed() is only needed if you want to reduce the
  max speed, typically if the PHY supports 1Gbps but the MAC
  supports 100Mbps only.

- The pause parameters are autonegotiated. Except you have a specific
  need you normally don't need to manually fiddle with this.

- phy_start_aneg() is called implicitly by the phylib state machine,
  you shouldn't call it manually except you have a good excuse.

- netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't
  needed. It's done by phy_link_change() in phylib.

c5715b8fab tcp: change txhash on SYN-data timeout
Previously upon SYN timeouts the sender recomputes the txhash to
try a different path. However this does not apply on the initial
timeout of SYN-data (active Fast Open). Therefore an active IPv6
Fast Open connection may incur one second RTO penalty to take on
a new path after the second SYN retransmission uses a new flow label.

This patch removes this undesirable behavior so Fast Open changes
the flow label just like the regular connections. This also helps
avoid falsely disabling Fast Open on the sender which triggers
after two consecutive SYN timeouts on Fast Open.

4f548c25a3 RISC-V Updates for 4.21-rc2 v2
This tag contains a handful of updates that slipped through the cracks
 during the merge window due to the holidays.  The fixes are mostly
 independent, with the exception of one larger audit-related branch.
 There's more information about the audit branch in that merge, the rest
 are:
 
 * The BSS has been moved, which shrinks flat images.
 * A fix to test-bpf so it compiles on RV64I-based systems.
 * A fix to respect the kernel commandline when there is no device tree.
 * A fix to prevent CPUs from trying to put themselves to sleep when
   bringing down the system.
 * Support for MODULE_SECTIONS on RV32I-based systems.
 * [new in v2] The addition of an SBI earlycon driver.  This is
   definately a new feature, but I'd like to include it now because I
   dropped this patch when submitting the merge window PR that removed our
   EARLY_PRINTK support.
 
 As usual, I've tested this by booting a Fedora-based image on a recent
 QEMU (this time just whatever I had lying around).

  RISC-V audit updates:

   - The addition of NR_syscalls into unistd.h, which is necessary for
     CONFIG_FTRACE_SYSCALLS.

   - The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit}
     get defined.

   - A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS

8544f4aa9d CIFS: Fix credit computation for compounded requests
In SMB3 protocol every part of the compound chain consumes credits
individually, so we need to call wait_for_free_credits() for each
of the PDUs in the chain. If an operation is interrupted, we must
ensure we return all credits taken from the server structure back.

Without this patch server can sometimes disconnect the session
due to credit mismatches, especially when first operation(s)
are large writes.

33fa5c8b8a CIFS: Do not set credits to 1 if the server didn't grant anything
Currently we reset the number of total credits granted by the server
to 1 if the server didn't grant us anything int the response. This
violates the SMB3 protocol - we need to trust the server and use
the credit values from the response. Fix this by removing the
corresponding code.

b983f7e923 CIFS: Fix adjustment of credits for MTU requests
Currently for MTU requests we allocate maximum possible credits
in advance and then adjust them according to the request size.
While we were adjusting the number of credits belonging to the
server, we were skipping adjustment of credits belonging to the
request. This patch fixes it by setting request credits to
CreditCharge field value of SMB2 packet header.

Also ask 1 credit more for async read and write operations to
increase parallelism and match the behavior of other operations.

b89d82ef01 arm64: kpti: Avoid rewriting early page tables when KASLR is enabled
A side effect of commit c55191e96c ("arm64: mm: apply r/o permissions
of VM areas to its linear alias as well") is that the linear map is
created with page granularity, which means that transitioning the early
page table from global to non-global mappings when enabling kpti can
take a significant amount of time during boot.

Given that most CPU implementations do not require kpti, this mainly
impacts KASLR builds where kpti is forcefully enabled. However, in these
situations we know early on that non-global mappings are required and
can avoid the use of global mappings from the beginning. The only gotcha
is Cavium erratum #27456, which we must detect based on the MIDR value
of the boot CPU.
