2015-04-22crush: straw2 bucket type with an efficient 64-bit crush_ln()Ilya Dryomov5-2/+316
This is an improved straw bucket that correctly avoids any data movement between items A and B when neither A nor B's weights are changed. Said differently, if we adjust the weight of item C (including adding it anew or removing it completely), we will only see inputs move to or from C, never between other items in the bucket. Notably, there is not intermediate scaling factor that needs to be calculated. The mapping function is a simple function of the item weights. The below commits were squashed together into this one (mostly to avoid adding and then yanking a ~6000 lines worth of crush_ln_table): - crush: add a straw2 bucket type - crush: add crush_ln to calculate nature log efficently - crush: improve straw2 adjustment slightly - crush: change crush_ln to provide 32 more digits - crush: fix crush_get_bucket_item_weight and bucket destroy for straw2 - crush/mapper: fix divide-by-0 in straw2 (with div64_s64() for draw = ln / w and INT64_MIN -> S64_MIN - need to create a proper compat.h in ceph.git) Reflects ceph.git commits 242293c908e923d474910f2b8203fa3b41eb5a53, 32a1ead92efcd351822d22a5fc37d159c65c1338, 6289912418c4a3597a11778bcf29ed5415117ad9, 35fcb04e2945717cf5cfe150b9fa89cb3d2303a1, 6445d9ee7290938de1e4ee9563912a6ab6d8ee5f, b5921d55d16796e12d66ad2c4add7305f9ce2353.

2015-04-22crush: ensuring at most num-rep osds are selectedIlya Dryomov1-4/+12
Crush temporary buffers are allocated as per replica size configured by the user. When there are more final osds (to be selected as per rule) than the replicas, buffer overlaps and it causes crash. Now, it ensures that at most num-rep osds are selected even if more number of osds are allowed by the rule. Reflects ceph.git commits 6b4d1aa99718e3b367496326c1e64551330fabc0, 234b066ba04976783d15ff2abc3e81b6cc06fb10. Signed-off-by: Ilya Dryomov <[email protected]>

2015-04-22modpost: don't emit section mismatch warnings for compiler optimizationsPaul Gortmaker1-0/+21
Currently an allyesconfig build [gcc-4.9.1] can generate the following: WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in reference from the function cpumask_empty.constprop.3() to the variable .init.data:nmi_ipi_mask which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c. Normally we would not see a symbol entry for cpumask_empty since it is: static inline bool cpumask_empty(const struct cpumask *srcp) however in this case, the variant of the symbol gets emitted when GCC does constant propagation optimization. Fix things up so that any locally optimized constprop variants don't warn when accessing variables that live in the __init sections.

2015-04-22modpost: expand pattern matching to support substring matchesPaul Gortmaker1-1/+11
Currently the match() function supports a leading * to match any prefix and a trailing * to match any suffix. However there currently is not a combination of both that can be used to target matches of whole families of functions that share a common substring. Here we expand the *foo and foo* match to also support *foo* with the goal of targeting compiler generated symbol names that contain strings like ".constprop." and ".isra."

2015-04-22modpost: fix extable entry size calculation.Quentin Casasnovas1-6/+10
As Guenter pointed out, we were never really calculating the extable entry size because the pointer arithmetic was simply wrong. We want to check we're handling the second relocation in __ex_table to infer an entry size, but we were using (void*) pointers instead of Elf_Rel[a]* ones. This fixes the problem by moving that check in the caller (since we can deal with different types of relocations) and add is_second_extable_reloc() to make the whole thing more readable.

As Guenter pointed out, we want to assert that extable_entry_size has been discovered and not the other way around. Moreover, this sanity check is only valid when we're not dealing with the first relocation in __ex_table, since we have not discovered the extable entry size at that point. This was leading to a divide-by-zero on some architectures and make the build fail.

2015-04-21ia64/PCI: Treat all host bridge Address Space Descriptors (even consumers) ↵Bjorn Helgaas1-4/+1
as windows Prior to c770cb4cb505 ("PCI: Mark invalid BARs as unassigned"), if we tried to claim a PCI BAR but could not find an upstream bridge window that matched it, we complained but still allowed the device to be enabled. c770cb4cb505 broke devices that previously worked (mptsas and igb in the case Tony reported, but it could be any devices) because it marks those BARs as IORESOURCE_UNSET, which makes pci_enable_device() complain and return failure: igb 0000:81:00.0: can't enable device: BAR 0 [mem size 0x00020000] not assigned igb: probe of 0000:81:00.0 failed with error -22 The underlying cause is an ACPI Address Space Descriptor for a PCI host bridge window that is marked as "consumer". This is a firmware defect: resources that are produced on the downstream side of a bridge should be marked "producer". But rejecting these BARs that we previously allowed is a functionality regression, and firmware has not used the producer/consumer bit consistently, so we can't rely on it anyway. Stop checking the producer/consumer bit, and assume all bridge Address Space Descriptors are for bridge windows. Note that this change does not affect I/O Port or Fixed Location I/O Port Descriptors, which are commonly used for the [io 0x0cf8-0x0cff] config access range. That range is a "consumer" range and should not be treated as a window.

vfs_fallocate will hit a NULL dereference if the client tries an ALLOCATE or DEALLOCATE with a special stateid. Fix that. (We also depend on the open to have broken any conflicting leases or delegations for us.) (If it turns out we need to allow special stateid's then we could do a temporary open here in the special-stateid case, as we do for read and write. For now I'm assuming it's not necessary.)

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty Pull tty/serial updates from Greg KH: "Here's the big tty/serial driver update for 4.1-rc1. It was delayed for a bit due to some questions surrounding some of the console command line parsing changes that are in here. There's still one tiny regression for people who were previously putting multiple console command lines and expecting them all to be ignored for some odd reason, but Peter is working on fixing that. If not, I'll send a revert for the offending patch, but I have faith that Peter can address it. Other than the console work here, there's the usual serial driver updates and changes, and a buch of 8250 reworks to try to make that driver easier to maintain over time, and have it support more devices in the future.
