Pull fbdev updates from Bartlomiej Zolnierkiewicz: "This time the pull request is really small. The most notable changes are fixing fbcon to not cause crash on unregister_framebuffer() operation when there is more than one framebuffer, adding config option to center the bootup logo and making FB_BACKLIGHT config option tristate (which in turn uncovered incorrect FB_BACKLIGHT usage by DRM's nouveau driver). Summary: - fix fbcon to not cause crash on unregister_framebuffer() when there is more than one framebuffer (Noralf Trønnes) - improve support for small rotated displays (Peter Rosin) - fix probe failure handling in udlfb driver (Dan Carpenter) - add config option to center the bootup logo (Peter Rosin) - make FB_BACKLIGHT config option tristate (Rob Clark) - remove superfluous HAS_DMA dependency for goldfishfb driver (Geert Uytterhoeven) - misc fixes (Alexey Khoroshilov, YueHaibing, Colin Ian King, Lubomir Rintel) - misc cleanups (Yangtao Li, Wen Yang) also there is DRM's nouveau driver fix for wrong FB_BACKLIGHT config option usage (FB_BACKLIGHT is for internal fbdev subsystem use only)" * tag 'fbdev-v4.21' of git://github.com/bzolnier/linux: drm/nouveau: fix incorrect FB_BACKLIGHT usage in Kconfig fbdev: fbcon: Fix unregister crash when more than one framebuffer fbdev: Remove depends on HAS_DMA in case of platform dependency pxa168fb: trivial typo fix fbdev: fsl-diu: remove redundant null check on cmap fbdev: omap2: omapfb: convert to DEFINE_SHOW_ATTRIBUTE fbdev: uvesafb: fix spelling mistake "memoery" -> "memory" fbdev: fbmem: add config option to center the bootup logo fbdev: fbmem: make fb_show_logo_line return the end instead of the height video: fbdev: pxafb: Fix "WARNING: invalid free of devm_ allocated data" fbdev: fbmem: behave better with small rotated displays and many CPUs video: clps711x-fb: release disp device node in probe() fbdev: make FB_BACKLIGHT a tristate udlfb: fix some inconsistent NULL checking

Pull ARM updates from Russell King: "Included in this update: - Florian Fainelli noticed that userspace segfaults caused by the lack of kernel-userspace helpers was hard to diagnose; we now issue a warning when userspace tries to use the helpers but the kernel has them disabled. - Ben Dooks wants compatibility for the old ATAG serial number with DT systems. - Some cleanup of assembly by Nicolas Pitre. - User accessors optimisation from Vincent Whitchurch. - More robust kdump on SMP systems from Yufen Wang. - Sebastian Andrzej Siewior noticed problems with the SMP "boot_lock" on RT kernels, and so we convert the Versatile series of platforms to use a raw spinlock instead, consolidating the Versatile implementation. We entirely remove the boot_lock on OMAP systems, where it's unnecessary.

This has been broken forever, and nobody ever really noticed because it's purely a performance issue. Long long ago, in commit 6175ddf0 ("x86: Clean up mem*io functions") Brian Gerst simplified the memory copies to and from iomem, since on x86, the instructions to access iomem are exactly the same as the regular instructions. That is technically true, and things worked, and nobody said anything. Besides, back then the regular memcpy was pretty simple and worked fine. Nobody noticed except for David Laight, that is. David has a testing a TLP monitor he was writing for an FPGA, and has been occasionally complaining about how memcpy_toio() writes things one byte at a time. Which is completely unacceptable from a performance standpoint, even if it happens to technically work. The reason it's writing one byte at a time is because while it's technically true that accesses to iomem are the same as accesses to regular memory on x86, the _granularity_ (and ordering) of accesses matter to iomem in ways that they don't matter to regular cached memory. In particular, when ERMS is set, we default to using "rep movsb" for larger memory copies. That is indeed perfectly fine for real memory, since the whole point is that the CPU is going to do cacheline optimizations and executes the memory copy efficiently for cached memory. With iomem? Not so much. With iomem, "rep movsb" will indeed work, but it will copy things one byte at a time. Slowly and ponderously. Now, originally, back in 2010 when commit 6175ddf0 was done, we didn't use ERMS, and this was much less noticeable. Our normal memcpy() was simpler in other ways too. Because in fact, it's not just about using the string instructions. Our memcpy() these days does things like "read and write overlapping values" to handle the last bytes of the copy. Again, for normal memory, overlapping accesses isn't an issue. For iomem? It can be. So this re-introduces the specialized memcpy_toio(), memcpy_fromio() and memset_io() functions. It doesn't particularly optimize them, but it tries to at least not be horrid, or do overlapping accesses. In fact, this uses the existing __inline_memcpy() function that we still had lying around that uses our very traditional "rep movsl" loop followed by movsw/movsb for the final bytes. Somebody may decide to try to improve on it, but if we've gone almost a decade with only one person really ever noticing and complaining, maybe it's not worth worrying about further, once it's not _completely_ broken?

This actually enables the __put_user_goto() functionality in unsafe_put_user(). For an example of the effect of this, this is the code generated for the unsafe_put_user(signo, &infop->si_signo, Efault); in the waitid() system call: movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_2] It's just one single store instruction, along with generating an exception table entry pointing to the Efault label case in case that instruction faults. Before, we would generate this: xorl %edx, %edx movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_3] testl %edx, %edx jne .L309 with the exception table generated for that 'mov' instruction causing us to jump to a stub that set %edx to -EFAULT and then jumped back to the 'testl' instruction. So not only do we now get rid of the extra code in the normal sequence, we also avoid unnecessarily keeping that extra error register live across it all.

This is finally the actual reason for the odd error handling in the "unsafe_get/put_user()" functions, introduced over three years ago. Using a "jump to error label" interface is somewhat odd, but very convenient as a programming interface, and more importantly, it fits very well with simply making the target be the exception handler address directly from the inline asm. The reason it took over three years to actually do this? We need "asm goto" support for it, which only became the default on x86 last year. It's now been a year that we've forced asm goto support (see commit e501ce95 "x86: Force asm-goto"), and so let's just do it here too. [ Side note: this commit was originally done back in 2016. The above commentary about timing is obviously about it only now getting merged into my real upstream tree - Linus ] Sadly, gcc still only supports "asm goto" with asms that do not have any outputs, so we are limited to only the put_user case for this. Maybe in several more years we can do the get_user case too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The alternative coding patch for parisc in kernel 4.20 broke booting machines with PA8500-PA8700 CPUs. The problem is, that for such machines the parisc kernel automatically utilizes huge pages to access kernel text code, but the set_kernel_text_rw() function, which is used shortly before applying any alternative patches, didn't used the correctly hugepage-aligned addresses to remap the kernel text read-writeable.

swap_readpage() wants to do polling to bring in pages if asked to, but it doesn't mark the bio as being polled. Additionally, the looping around the blk_poll() check isn't correct - if we get a zero return, we should call io_schedule(), we can't just assume that the bio has completed. The regular bio->bi_private check should be used for that.
