2020-05-27Fix pmon_iostrategy()Visa Hankala
If rsize is NULL, do not update the variable. Otherwise the bootloader will crash when it invokes libsa's fchmod(). This lets the bootloader work again after the recent loadrandom() change. The fix should also improve the chances of sysupgrade(8) on loongson. Note that pmon_iostrategy() does not allow writing. fchmod() will fail but does not prevent boot.

2020-05-27raise max columns and rows in efifb to 160Jonathan Gray
This is the same change made in rev 1.21 to match the drm drivers. It was reverted as Lucas Raab reported problems with inteldrm taking over the fb with a 4k display. Lucas confirmed that this is no longer an issue. Prompted by a similar patch from John Carmack to raise the limits. ok kettenis@

2020-05-26iodcstrategy() maintains a cache for READ performance (tapes are supportedTheo de Raadt
here, and alternatively would need to rewind). WRITE code exists, but was always wrong -- it writes the cache-buffer to disk, rather than the provided write-buffer. Copy the write-buffer into the cache, and invalidate the cache completely so that future reads start from scratch.
2020-05-26Check outcome of loadrandom() on octeonVisa Hankala
If loadrandom() succeeds, set RB_GOODRANDOM in boothowto. To enable fchmod(), disk_open() has to mount the filesystem in writable mode. This is tricky because the filesystem might be unclean. Hence the code has to use MNT_FORCE. Input and OK deraadt@
2020-05-26Rework kernel loading with octboot(4)Visa Hankala
Load the kernel image from the filesystem upfront in rdboot and pass the loaded image to octboot(4)'s kexec call in a memory buffer. As a result, octboot(4) does not rely on a mounted filesystem. OK deraadt@
2020-05-26Rewrite m88k mutex code as a slight variation of the MI mutex code.Kenji Aoyama
This will make mutex spinning time visible in top(1), and also might improve stability. The major change in this is that the old assembly code acquires mutexes with an atomic exchange operation, but releases them with a regular store, but the new code always uses atomic exchange operations. The mutex.h changes to the macros conform to <sys/mutex.h> to be able to reset the system while in ddb. Suggested from Miod Vallat, tested by me. The stability in heavy load is greatly improved in my case.

2020-05-25change wsdisplay attribute type from long to uint32_tJonathan Gray
miod explained it was initially a long as it was thought drivers may need to allocate storage but in practice they don't need more than 32 bits for an attribute. suggested and reviewed by miod@

This lets the kernel detect retguard traps and send SIGABRT instead of SIGEMT. SIGEMT does not indicate correctly the nature of the error (stack overflow, violation of control flow).
