2019-12-19xdp: Remove map_to_flush and map swap detectionBjörn Töpel
Now that all XDP maps that can be used with bpf_redirect_map() tracks entries to be flushed in a global fashion, there is not need to track that the map has changed and flush from xdp_do_generic_map() anymore. All entries will be flushed in xdp_do_flush_map(). This means that the map_to_flush can be removed, and the corresponding checks. Moving the flush logic to one place, xdp_do_flush_map(), give a bulking behavior and performance boost.

2019-12-19xdp: Make cpumap flush_list common for all map instancesBjörn Töpel
The cpumap flush list is used to track entries that need to flushed from via the xdp_do_flush_map() function. This list used to be per-map, but there is really no reason for that. Instead make the flush list global for all devmaps, which simplifies __cpu_map_flush() and cpu_map_alloc().

The new Qdisc operates like the PRIO / DRR combo would when configured as per the standard. The strict classes, if any, are tried for traffic first.

2019-12-18y2038: sparc: remove use of struct timexArnd Bergmann
'struct timex' is one of the last users of 'struct timeval' and is only referenced in one place in the kernel any more, to convert the user space timex into the kernel-internal version on sparc64, with a different tv_usec member type. As a preparation for hiding the time_t definition and everything using that in the kernel, change the implementation once more to only convert the timeval member, and then enclose the struct definition in an #ifdef.

2019-12-18nfs: use time64_t internallyArnd Bergmann
The timestamps for the cache are all in boottime seconds, so they don't overflow 32-bit values, but the use of time_t is deprecated because it generally does overflow when used with wall-clock time. There are multiple possible ways of avoiding it: - leave time_t, which is safe here, but forces others to look into this code to determine that it is over and over. - use a more generic type, like 'int' or 'long', which is known to be sufficient here but loses the documentation of referring to timestamps - use ktime_t everywhere, and convert into seconds in the few places where we want realtime-seconds. The conversion is sometimes expensive, but not more so than the conversion we do today. - use time64_t to clarify that this code is safe. Nothing would change for 64-bit architectures, but it is slightly less efficient on 32-bit architectures. Without a clear winner of the three approaches above, this picks the last one, favouring readability over a small performance loss on 32-bit architectures. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2019-12-18sunrpc: convert to time64_t for expiryArnd Bergmann
Using signed 32-bit types for UTC time leads to the y2038 overflow, which is what happens in the sunrpc code at the moment. This changes the sunrpc code over to use time64_t where possible. The one exception is the gss_import_v{1,2}_context() function for kerberos5, which uses 32-bit timestamps in the protocol. Here, we can at least treat the numbers as 'unsigned', which extends the range from 2038 to 2106. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2019-12-18tsacct: add 64-bit btime fieldArnd Bergmann
As there is only a 32-bit ac_btime field in taskstat and we should handle dates after the overflow, add a new field with the same information but 64-bit width that can hold a full time64_t. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2019-12-18acct: stop using get_seconds()Arnd Bergmann
In 'struct acct', 'struct acct_v3', and 'struct taskstats' we have a 32-bit 'ac_btime' field containing an absolute time value, which will overflow in year 2106. There are two possible ways to deal with it: a) let it overflow and have user space code deal with reconstructing the data based on the current time, or b) truncate the times based on the range of the u32 type. Neither of them solves the actual problem. Pick the second one to best document what the issue is, and have someone fix it in a future version. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2019-12-18tty/serial: Migrate 8250_fsl to use has_sysrqDmitry Safonov
The SUPPORT_SYSRQ ifdeffery is not nice as: - May create misunderstanding about sizeof(struct uart_port) between different objects - Prevents moving functions from serial_core.h - Reduces readability (well, it's ifdeffery - it's hard to follow) In order to remove SUPPORT_SYSRQ, has_sysrq variable has been added. Initialise it in driver's probe and remove ifdeffery. In contrast to 8250/8250_of, legacy_serial on powerpc does fill (struct plat_serial8250_port). The reason is likely that it's done on device_initcall(), not on probe. So, 8250_core is not yet probed. Propagate value from platform_device on 8250 probe - in case powepc legacy driver it's initialized on initcall, in case 8250_of it will be initialized later on of_platform_serial_setup().

Now that invert_gpio arguments are unused, let's remove them. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Link: https://lore.kernel.org/r/64d766d1f8af2e22bce32f4ffa453f7234207ad6.1576031637.git.mirq-linux@rere.qmqm.pl Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2019-12-18gpio: add gpiod_toggle_active_low()Michał Mirosław
Add possibility to toggle active-low flag of a gpio descriptor. This is useful for compatibility code, where defaults are inverted vs DT gpio flags or the active-low flag is taken from elsewhere.

2019-12-18rtc: rv3029: let the core handle rtc rangeAlexandre Belloni
Despite the comment, the RV3029 uses a 7bit BCD register for the year, making 2079 the last supported year. Link: https://lore.kernel.org/r/20191214221022.622482-14-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2019-12-18rtc: define RTC_VL_READ valuesAlexandre Belloni
Currently, the meaning of the value returned by RTC_VL_READ is undocumented and left to the driver implementation. In order to get more meaningful values, define a set of values to use as to make clear to userspace what is the status of the various voltages feeding the RTC.
