2016-02-16mm/gup: Switch all callers of get_user_pages() to not pass tsk/mmDave Hansen2-4/+1
We will soon modify the vanilla get_user_pages() so it can no longer be used on mm/tasks other than 'current/current->mm', which is by far the most common way it is called. For now, we allow the old-style calls, but warn when they are used. (implemented in previous patch) This patch switches all callers of: get_user_pages() get_user_pages_unlocked() get_user_pages_locked() to stop passing tsk/mm so they will no longer see the warnings.

This patch replaces timeval with timespec64 as 32 bit 'struct timeval' will not give current time beyond year 2038. The patch changes the code to use ktime_get_real_ts64() which returns a 'struct timespec64' instead of do_gettimeofday() which returns a 'struct timeval' This patch also alters the format strings in sprintf() for now.tv_sec and now.tv_nsec to incorporate 'long long' on 32 bit architectures and leading zeroes respectively.

2016-02-11misc: panel, convert struct to bitmapDaniel Chromik1-47/+40
There is an anonymous struct which is actually used as a bitmap. So convert the struct to a bitmap and change code accordingly where needed. This also allows for a cleanup of set_data_bits and set_ctrl_bits as they can use a common helper now. The helper can also be converted to a for loop instead of doing bit OR. And given it is a for loop now, bit masking (using BIT_MSK) is moved from the callers there too.

Atmel devices in this family have some quirks not found in other similar chips - they do not support a sequential read of the entire EEPROM contents, and the control word sent at the start of each operation varies in bit length. This commit adds quirk support to the driver and modifies the read implementation to support non-sequential reads for consistency with other misc/eeprom drivers.

2016-02-09misc: mic: MIC VOP BusSudeep Dutt4-0/+361
The Virtio Over PCIe (VOP) bus abstracts the low level hardware details like interrupts and mapping remote memory so that the same VOP driver can work without changes with different MIC host or card drivers as long as the hardware bus operations are implemented. The VOP driver registers itself on the VOP bus. The base PCIe drivers implement the bus ops and register VOP devices on the bus, resulting in the VOP driver being probed with the VOP devices. This allows the VOP functionality to be shared between multiple generations of Intel MIC products.

The kernel sometimes fails to link when lkdrm is built-in and compiled with clang: relocation truncated to fit: R_ARM_THM_CALL against `.bss' The reason here is that a relocation from .text to .bss fails to generate a trampoline because .bss is not an executable section. Marking the function 'noinline' turns the relative branch to .bss into an absolute branch to the function argument, and that works fine.

However, the offset parameter passed in when reading or writing at a specific location is always specified in terms of bytes.

2016-02-07drivers/misc: make arm-charlcd.c explicitly non-modularPaul Gortmaker1-22/+2
The Kconfig currently controlling compilation of this code is: drivers/misc/Kconfig:config ARM_CHARLCD drivers/misc/Kconfig: bool "ARM Ltd. Character LCD Driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and this driver did not have a ".remove" function coded for non-modular drivers either. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2016-02-07VMCI: Use 32bit atomics for queue headers on X86_32Jorgen Hansen1-1/+1
This change restricts the reading and setting of the head and tail pointers on 32bit X86 to 32bit for both correctness and performance reasons. On uniprocessor X86_32, the atomic64_read may be implemented as a non-locked cmpxchg8b. This may result in updates to the pointers done by the VMCI device being overwritten. On MP systems, there is no such correctness issue, but using 32bit atomics avoids the overhead of the locked 64bit operation. All this is safe because the queue size on 32bit systems will never exceed a 32bit value.
