From SAMA5D4, the watchdog timer is upgrated with a new feature, which is describled as in the datasheet, "WDT_MR can be written until a LOCKMR command is issued in WDT_CR". That is to say, as long as the bootstrap and u-boot don't issue a LOCKMR command, WDT_MR can be written more than once in the driver. So the SAMA5D4 watchdog driver's implementation is different from the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c. The user application open the device file to enable the watchdog timer hardware, and close to disable it, and set the watchdog timer timeout by seting WDV and WDD fields of WDT_MR register, and ping the watchdog by issuing WDRSTT command to WDT_CR register with hard-coded key.

Since commit ef90174f ("watchdog: watchdog_core: Add watchdog registration deferral mechanism") there is no need to delay the call to watchdog_register_device any more. So simplify the registration code accordingly. Resetting wd_base to NULL can the also be dropped because nothing depends on it being NULL to signal probe failure any more. (The matching wd_base = NULL in .remove was missing, too.)

This commit adds support for the watchdog timer found in NXP LPC SoCs family, which includes LPC18xx/LPC43xx. Other SoCs in that family may share the same watchdog hardware. Watchdog driver registers a restart handler that will restart the system by performing an incorrect feed after ensuring the watchdog is enabled in reset mode. As watchdog cannot be disabled in hardware, driver's stop routine will regularly send a keepalive ping using a timer.

During probe for an always-running watchdog a timer is setup to constantly ping the watchdog while the device is not open. The gpio to ping the watchdog is setup to inactive. For a watchdog with hw_algo = "toggle" this results in a ping depending on the initial state of the gpio, for hw_algo = "level" no ping is generated. Make sure that the first automatic ping is sent immediately and not only when the timer expires the first time. This makes the machine survive in case more than half of the watchdog timeout is already elapsed. (Which is very probable for the chip I'm faced with that has a timeout of one second.)

strncmp(algo, "toggle", 6) doesn't compare the trailing '\0' byte, so using hw_algo = "toggleboggle" is recognized the same way as hw_algo = "toggle" . While this doesn't introduce any problems for a device tree that sticks to the documented settings it's still ugly. Fix this by using strcmp to only match on "toggle" and "level".

Without .shutdown(), watchdog might reset the system during power off. For example, if watchdog's timeout is set to 30s, then it is reset to zero by mtk_wdt_ping(). During power off, no app will ping watchdog, but watchdog is still running and may trigger reset.

Don't try to copy the registers, the soft state will be copied by fork anyway, so the child task inherits the parent task's soft math state. With this fix applied math-emu kernels boot up fine on modern hardware and the 'no387 nofxsr' boot options.

The long term fix might be to allow math-emu to execute (certain) kernel mode FPU instructions, but for now apply the safe (albeit somewhat ugly) fix: initialize the emulation state explicitly without trapping out to the FPU emulator.

Commit c48a11c7 ("netvm: propagate page->pfmemalloc to skb") added checks for page->pfmemalloc to __skb_fill_page_desc(): if (page->pfmemalloc && !page->mapping) skb->pfmemalloc = true; It assumes page->mapping == NULL implies that page->pfmemalloc can be trusted. However, __delete_from_page_cache() can set set page->mapping to NULL and leave page->index value alone. Due to being in union, a non-zero page->index will be interpreted as true page->pfmemalloc. So the assumption is invalid if the networking code can see such a page. And it seems it can. We have encountered this with a NFS over loopback setup when such a page is attached to a new skbuf. There is no copying going on in this case so the page confuses __skb_fill_page_desc which interprets the index as pfmemalloc flag and the network stack drops packets that have been allocated using the reserves unless they are to be queued on sockets handling the swapping which is the case here and that leads to hangs when the nfs client waits for a response from the server which has been dropped and thus never arrive. The struct page is already heavily packed so rather than finding another hole to put it in, let's do a trick instead. We can reuse the index again but define it to an impossible value (-1UL). This is the page index so it should never see the value that large. Replace all direct users of page->pfmemalloc by page_is_pfmemalloc which will hide this nastiness from unspoiled eyes. The information will get lost if somebody wants to use page->index obviously but that was the case before and the original code expected that the information should be persisted somewhere else if that is really needed (e.g. what SLAB and SLUB do).
