mm: remove include/linux/bootmem.h

2018-10-31T15:54:16+00:00

Move remaining definitions and declarations from include/linux/bootmem.h into include/linux/memblock.h and remove the redundant header.

memblock: replace free_bootmem{_node} with memblock_free

2018-10-31T15:54:16+00:00

The free_bootmem and free_bootmem_node are merely wrappers for memblock_free.

memblock: replace alloc_bootmem_pages_nopanic with memblock_alloc_nopanic

2018-10-31T15:54:15+00:00

The alloc_bootmem_pages_nopanic(size) is a shortcut for __alloc_bootmem_nopanic(size, PAGE_SIZE, BOOTMEM_LOW_LIMIT) which allocates PAGE_SIZE aligned memory. Since BOOTMEM_LOW_LIMIT is hardwired to 0 there is no restrictions on where the allocated memory should reside. The memblock_alloc_nopanic(size, PAGE_SIZE) also allocates PAGE_SIZE aligned memory without any restrictions and thus can be used as a replacement for alloc_bootmem_pages_nopanic() Link: http://lkml.kernel.org/r/1536927045-23536-12-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport Acked-by: Michal Hocko Cc: Catalin Marinas Cc: Chris Zankel Cc: "David S.

usb: early: Correct the endpoint type value for bulk in endpoint

2017-12-07T15:03:15+00:00

This corrects the endpiont type value set to the DbC bulk in endpoint. The previous value doesn't cause any problems because that we now only use the bulk out endpoint. Set the hardware with the correct value any way. Signed-off-by: Lu Baolu Signed-off-by: Greg Kroah-Hartman

USB: add SPDX identifiers to all remaining Makefiles

2017-11-07T14:53:48+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. This updates the remaining drivers/usb/*Makefile* that were missing SPDX identifiers. They all get the following identifier: SPDX-License-Identifier: GPL-2.0 The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

USB: early: Remove redundant license text

2017-11-07T14:45:02+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: early: Use new USB product ID and strings for DbC device

2017-11-07T14:34:08+00:00

The DbC register set defines an interface for system software to specify the vendor id and product id for the debug device. These two values will be presented by the debug device in its device descriptor idVendor and idProduct fields. The current used product ID is a place holder. We now have a valid one. The description strings are changed accordingly. This patch should be back-ported to kernels as old as v4.12, that contain the commit aeb9dd1de98c ("usb/early: Add driver for xhci debug capability").

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb/early: Remove trace_printk() callers in xhci-dbc

2017-06-13T08:54:40+00:00

Trace_printk() was used to log debug messages in xhci-dbc.c where printk() isn't feasible. As there should not be a single caller to trace_printk() in normal kernels, replace them with empty functions.
