[PATCH] arm64: dts: hikey: Revert "Enable HS200 mode on eMMC"

by John Stultz

From: Alistair Strachan <astrachan(a)google.com> This reverts commit abd7d0972a192ee653efc7b151a6af69db58f2bb. This change was already partially reverted by John Stultz in commit 9c6d26df1fae ("arm64: dts: hikey: Fix eMMC corruption regression"). This change appears to cause controller resets and block read failures which prevents successful booting on some hikey boards.

+ revert-mm-dont-reclaim-inodes-with-many-attached-pages.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: Revert "mm: don't reclaim inodes with many attached pages" has been added to the -mm tree. Its filename is revert-mm-dont-reclaim-inodes-with-many-attached-pages.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/revert-mm-dont-reclaim-inodes-with… and later at http://ozlabs.org/~akpm/mmotm/broken-out/revert-mm-dont-reclaim-inodes-with… 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: Dave Chinner <dchinner(a)redhat.com> Subject: Revert "mm: don't reclaim inodes with many attached pages" This reverts commit a76cf1a474d7dbcd9336b5f5afb0162baa142cf0. This change causes serious changes to page cache and inode cache behaviour and balance, resulting in major performance regressions when combining worklaods such as large file copies and kernel compiles. https://bugzilla.kernel.org/show_bug.cgi?id=202441 This change is a hack to work around the problems introduced by changing how agressive shrinkers are on small caches in commit 172b06c32b94 ("mm: slowly shrink slabs with a relatively small number of objects"). It creates more problems than it solves, wasn't adequately reviewed or tested, so it needs to be reverted.

[PATCH v2 1/2] arm: cns3xxx: fix writing to wrong PCI registers after alignment

by Koen Vandeputte

Originally, cns3xxx used it's own functions for mapping, reading and writing registers. Commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors") removed the internal PCI config write function in favor of the generic one: cns3xxx_pci_write_config() --> pci_generic_config_write() cns3xxx_pci_write_config() expected aligned addresses, being produced by cns3xxx_pci_map_bus() while the generic one pci_generic_config_write() actually expects the real address as both the function and hardware are capable of byte-aligned writes. This currently leads to pci_generic_config_write() writing to the wrong registers on some ocasions. First issue seen due to this: - driver ath9k gets loaded - The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER, located at 0x0D - cns3xxx_pci_map_bus() aligns the address to 0x0C - pci_generic_config_write() effectively writes 0xA8 into register 0x0C (CACHE_LINE_SIZE) This seems to cause some slight instability when certain PCI devices are used. Another issue example caused by this this is the PCI bus numbering, where the primary bus is higher than the secondary, which is impossible. Before: 00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0, IRQ 255 Bus: primary=02, secondary=01, subordinate=ff, sec-latency=0 After fix: 00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0, IRQ 255 Bus: primary=00, secondary=01, subordinate=02, sec-latency=0 And very likely some more .. Fix all by omitting the alignment being done in the mapping function.

[PATCH] gfs2: Revert "Fix loop in gfs2_rbm_find"

by Andreas Gruenbacher

This reverts commit 2d29f6b96d8f80322ed2dd895bca590491c38d34. It turns out that the fix can lead to a ~20 percent performance regression in initial writes to the page cache according to iozone. Let's revert this for now to have more time for a proper fix.
