[PATCH] mm/page_alloc: fix memmap_init_zone pageblock alignment

by Daniel Vacek

In move_freepages() a BUG_ON() can be triggered on uninitialized page structures due to pageblock alignment. Aligning the skipped pfns in memmap_init_zone() the same way as in move_freepages_block() simply fixes those crashes.

+ h8300-remove-extranous-__big_endian-definition.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: h8300: remove extranous __BIG_ENDIAN definition has been added to the -mm tree. Its filename is h8300-remove-extranous-__big_endian-definition.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/h8300-remove-extranous-__big_endia… and later at http://ozlabs.org/~akpm/mmotm/broken-out/h8300-remove-extranous-__big_endia… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Arnd Bergmann <arnd(a)arndb.de> Subject: h8300: remove extranous __BIG_ENDIAN definition A bugfix I did earlier caused a build regression on h8300, which defines the __BIG_ENDIAN macro in a slightly different way than the generic code: arch/h8300/include/asm/byteorder.h:5:0: warning: "__BIG_ENDIAN" redefined We don't need to define it here, as the same macro is already provided by the linux/byteorder/big_endian.h, and that version does not conflict. While this is a v4.16 regression, my earlier patch also got backported to the 4.14 and 4.15 stable kernels, so we need the fixup there as well.

patch "serial: 8250: Add Nuvoton NPCM UART" added to tty-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250: Add Nuvoton NPCM UART to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From f597fbce38d230af95384f4a04e0a13a1d0ad45d Mon Sep 17 00:00:00 2001 From: Joel Stanley <joel(a)jms.id.au> Date: Mon, 5 Mar 2018 22:17:38 +1030 Subject: serial: 8250: Add Nuvoton NPCM UART The Nuvoton UART is almost compatible with the 8250 driver when probed via the 8250_of driver, however it requires some extra configuration at startup.

[PATCH 1/2] x86/mm: fix vmalloc_fault to use pXd_large

by Toshi Kani

Gratian Crisan reported that vmalloc_fault() crashes when CONFIG_HUGETLBFS is not set since the function inadvertently uses pXn_huge(), which always return 0 in this case. ioremap() does not depend on CONFIG_HUGETLBFS. Fix vmalloc_fault() to call pXd_large() instead. fixes: f4eafd8bcd52 ("x86/mm: Fix vmalloc_fault() to handle large pages properly") Reported-by: Gratian Crisan <gratian.crisan(a)ni.com> Signed-off-by: Toshi Kani <toshi.kani(a)hpe.com> Cc: Thomas Gleixner <tglx(a)linutronix.de> Cc: Ingo Molnar <mingo(a)redhat.com> Cc: "H.
