ia64: move from strlcpy with unused retval to strscpy

2022-09-12T04:55:09+00:00

Follow the advice of the below link and prefer 'strscpy' in this
subsystem.  Conversion is 1:1 because the return value is not used.

arch/ia64: replace cpumask_weight with cpumask_empty where appropriate

2022-06-03T13:52:57+00:00

setup_arch() calls cpumask_weight() to check if any bit of a given cpumask
is set. We can do it more efficiently with cpumask_empty() because
cpumask_empty() stops traversing the cpumask as soon as it finds first set
bit, while cpumask_weight() counts all bits unconditionally.

arch/ia64/kernel/setup.c: use swap() to make code cleaner

2022-01-15T14:30:24+00:00

Use the macro 'swap()' defined in 'include/linux/minmax.h' to avoid
opencoding it.

ia64: make reserve_elfcorehdr() static

2021-09-03T16:58:09+00:00

There never was a reason for reserve_elfcorehdr() to be global.  Make the
function static, and move it before its sole caller.

ia64: fix #endif comment for reserve_elfcorehdr()

2021-09-03T16:58:09+00:00

Patch series "ia64: Miscellaneous fixes and cleanups".

This patch series contains some miscellaneous fixes and cleanups for ia64.
The second patch fixes a naming conflict triggered by a patch for the FDT
code.

This patch (of 3):

The definition of reserve_elfcorehdr() depends on CONFIG_CRASH_DUMP, not
CONFIG_PROC_VMCORE.

locking, arch/ia64: Reduce header dependencies by moving XTP bits into the new header

2020-08-06T14:13:13+00:00

We want to remove the #include  from , but for this
we have to move the XTP bits into a separate header first (as these bits
rely on  definitions), and include them in the .c files that rely
on those APIs.

mm: reorder includes after introduction of linux/pgtable.h

2020-06-09T16:39:13+00:00

The replacement of  with  made the include
of the latter in the middle of asm includes.  Fix this up with the aid of
the below script and manual adjustments here and there.

	    print "USAGE: %s  " % (sys.argv[0])

mm: introduce include/linux/pgtable.h

2020-06-09T16:39:13+00:00

The include/linux/pgtable.h is going to be the home of generic page table
manipulation functions.

Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and
make the latter include asm/pgtable.h.
