2014-04-11x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernelsH. Peter Anvin1-0/+11
The IRET instruction, when returning to a 16-bit segment, only restores the bottom 16 bits of the user space stack pointer. We have a software workaround for that ("espfix") for the 32-bit kernel, but it relies on a nonzero stack segment base which is not available in 32-bit mode. Since 16-bit support is somewhat crippled anyway on a 64-bit kernel (no V86 mode), and most (if not quite all) 64-bit processors support virtualization for the users who really need it, simply reject attempts at creating a 16-bit segment when running on top of a 64-bit kernel.

2014-04-10NVMe: Retry failed commands with non-fatal errorsKeith Busch4-96/+154
For commands returned with failed status, queue these for resubmission and continue retrying them until success or for a limited amount of time. The final timeout was arbitrarily chosen so requests can't be retried indefinitely. Since these are requeued on the nvmeq that submitted the command, the callbacks have to take an nvmeq instead of an nvme_dev as a parameter so that we can use the locked queue to append the iod to retry later. The nvme_iod conviently can be used to track how long we've been trying to successfully complete an iod request. The nvme_iod also provides the nvme prp dma mappings, so I had to move a few things around so we can keep those mappings.

2014-04-10NVMe: per-cpu io queuesKeith Busch2-38/+172
The device's IO queues are associated with CPUs, so we can use a per-cpu variable to map the a qid to a cpu. This provides a convienient way to optimally assign queues to multiple cpus when the device supports fewer queues than the host has cpus. The previous implementation may have assigned these poorly in these situations. This patch addresses this by sharing queues among cpus that are "close" together and should have a lower lock contention penalty.

2014-04-10efi: Pass correct file handle to efi_file_{read,close}Matt Fleming2-9/+9
We're currently passing the file handle for the root file system to efi_file_read() and efi_file_close(), instead of the file handle for the file we wish to read/close. While this has worked up until now, it seems that it has only been by pure luck. Olivier explains, "The issue is the UEFI Fat driver might return the same function for 'fh->read()' and 'h->read()'. While in our case it does not work with a different implementation of EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. In our case, we return a different pointer when reading a directory and reading a file." Fixing this actually clears up the two functions because we can drop one of the arguments, and instead only pass a file 'handle' argument.

code32_start should point at the start of the protected mode code, and *not* at the beginning of the bzImage. This is much easier to do in assembly so document that callers of make_boot_params() need to fill out code32_start. The fallout from this bug is that we would end up relocating the image but copying the image at some offset, resulting in what appeared to be memory corruption.

commit 54b52d872680 ("x86/efi: Build our own EFI services pointer table") introduced a regression because the 64-bit file_size() implementation passed a pointer to a 32-bit data object, instead of a pointer to a 64-bit object. Because the firmware treats the object as 64-bits regardless it was reading random values from the stack for the upper 32-bits. This resulted in people being unable to boot their machines, after seeing the following error messages, Failed to get file info size Failed to alloc highmem for files Reported-by: Dzmitry Sledneu <dzmitry.sledneu@gmail.com> Reported-by: Koen Kooi <koen@dominion.thruhere.net> Tested-by: Koen Kooi <koen@dominion.thruhere.net> Signed-off-by: Matt Fleming <matt.fleming@intel.com>

Pull block layer fixes from Jens Axboe: "A small collection of fixes that should go in before -rc1. The pull request contains: - A two patch fix for a regression with block enabled tagging caused by a commit in the initial pull request. One patch is from Martin and ensures that SCSI doesn't truncate 64-bit block flags, the other one is from me and prevents us from double using struct request queuelist for both completion and busy tags. This caused anything from a boot crash for some, to crashes under load. - A blk-mq fix for a potential soft stall when hot unplugging CPUs with busy IO. - percpu_counter fix is listed in here, that caused a suspend issue with virtio-blk due to percpu counters having an inconsistent state during CPU removal.

The patch states that it is safe to reuse queuelist at completion time, since it is no longer used. However, that is not true if a device is using block enabled tagging. If that is the case, then the queuelist is reused to keep track of busy tags. If a device also ended up using softirq completions, we'd reuse ->queuelist for the IPI handling while block tagging was still using it. Boom. Fix this by adding a new ipi_list list head, and share the memory used with the request hash table. The hash table is never used after the request is moved to the dispatch list, which happens long before any potential completion of the request. Add a new request bit for this, so we don't have cases that check rq->hash while it could potentially have been reused for the IPI completion. Reported-by: Martin K.

It got a little delayed because I needed to wait for a dependency to be included (commit b424080a9e08: "reset: Add optional resets and stubs"). Plus, I had some email problems. All done now, the highlights are: - drivers can now deprecate their use of i2c classes. That shouldn't be used on embedded platforms anyhow and was often blindly copy&pasted. This mechanism gives users time to switch away and ultimately boot faster once the use of classes for those drivers is gone for good. - new drivers for QUP, Cadence, efm32 - tracepoint support for I2C and SMBus - bigger cleanups for the mv64xxx, nomadik, and designware drivers And the usual bugfixes, cleanups, feature additions.
