The scrub rate control register has moved to function 2 in PCI config space and is at a different offset on family 0x15, models 0x60 and later. The minimum recommended scrub rate has also changed. (Refer to D18F2x1c9_dct[1:0][DramScrub] in Fam15hM60h BKDG). Adjust set_scrub_rate() and get_scrub_rate() functions to accommodate this. Tested on F15hM60h, Fam15h, models 00h-0fh and Fam10h systems.

Sysfs "dimm_label" and "chX_dimm_label" nodes have the following issues in their store operation: 1) A newline-terminated input string causes redundant newlines: # echo "test" > /sys/bus/mc0/devices/dimm0/dimm_label # cat /sys/bus/mc0/devices/dimm0/dimm_label test # od -bc /sys/bus/mc0/devices/dimm0/dimm_label 0000000 164 145 163 164 012 012 t e s t \n \n 0000006 2) The original label string (31 characters) cannot be stored due to an improper size check: # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0" > /sys/bus/mc0/devices/dimm0/dimm_label # cat /sys/bus/mc0/devices/dimm0/dimm_label # od -bc /sys/bus/mc0/devices/dimm0/dimm_label 0000000 012 012 \n \n 0000002 3) An input string longer than the buffer size results a wrong label info as it allows a retry with the remaining string: # echo "CPU_SrcID#0_Ha#0_Chan#0_DIMM#0_TEST" > /sys/bus/mc0/devices/dimm0/dimm_label # cat /sys/bus/mc0/devices/dimm0/dimm_label _TEST Fix these issues by making the following changes: 1) Replace a newline character at the end by setting a null. It also assures that the string is null-terminated in the label buffer. 2) Check the label buffer size with 'sizeof(dimm->label)'. 3) Fail a request if its string exceeds the label buffer size.

由 Seth Jennings 提交于
In commit 7d375bff ("sb_edac: Fix support for systems with two home agents per socket") NUM_CHANNELS was changed to 8 and the channel space was renumerated to handle EN, EP, and EX configurations. The *_mci_bind_devs() functions - except for sbridge_mci_bind_devs() - got a new device presence check in the form of saw_chan_mask. However, sbridge_mci_bind_devs() still uses the NUM_CHANNELS for loop. With the increase in NUM_CHANNELS, this loop fails at index 4 since SB only has 4 TADs. This results in the following error on SB machines: EDAC sbridge: Some needed devices are missing EDAC sbridge: Couldn't find mci handler EDAC sbridge: Couldn't find mci handle This patch adapts the saw_chan_mask logic for sbridge_mci_bind_devs() as well.

Commit 505a666e ("writeback: plug writeback in wb_writeback() and writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes, which increases the merge rate when relatively contiguous small files are written by the filesystem. It helps both on flash and spindles. For an fs_mark workload creating 4K files in parallel across 8 drives, this commit improves performance ~9% more by unplugging before calling cond_resched(). cond_resched() doesn't trigger an implicit unplug, so explicitly getting the IO down to the device before scheduling reduces latencies for anyone waiting on clean pages. It also cuts down on how often we use kblockd to unplug, which means less work bouncing from one workqueue to another. Many more details about how we got here: https://lkml.org/lkml/2015/9/11/570Signed-off-by: NChris Mason <clm@fb.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The various definitions of __pfn_to_phys() have been consolidated to use a generic macro in include/asm-generic/memory_model.h. This hit mainline in the form of 012dcef3 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication.

Some of the device files are required to be user accessible for PSM while most should remain accessible only by root. Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions. Finally remove the unnecessary null check before class_destroy Tested-by: NDonald Dutile <ddutile@redhat.com> Signed-off-by: Haralanov, Mitko (mitko.haralanov@intel.com) Signed-off-by: NIra Weiny <ira.weiny@intel.com> Signed-off-by: NDoug Ledford <dledford@redhat.com>

I added spaces around operators so it matches kernel style because normally "-1ULL" is a number and " - 1" is a subtract operation. Also removed some superflous "ULL" types so "1ULL" becomes "1".
