s390: kernel: convert timeouts to use secs_to_jiffies()

2025-01-13T04:21:01+00:00

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies().  As the values here are a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.

This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:

@@ constant C; @@

- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)

@@ constant C; @@

- msecs_to_jiffies(C * MSEC_PER_SEC)
+ secs_to_jiffies(C)

s390/lgr: use simple assignment instead of memcpy

2022-02-06T22:31:29+00:00

It is quite pointless to use memcpy to copy two bytes, besides that
this construct will also partially remove type and size sanity checks.

Therefore simply use an assignment.

s390: convert to msecs_to_jiffies()

2020-06-29T14:31:46+00:00

Instead of using the old 'jiffies + HZ {/,*} something' calculation
use msecs_to_jiffies() as that makes the code more readable.

s390: kernel: add SPDX identifiers to the remaining files

2017-11-24T14:37:12+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 arch/s390/kernel/ 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.

timer: Remove users of TIMER_DEFERRED_INITIALIZER

2017-10-05T13:01:18+00:00

This removes uses of TIMER_DEFERRED_INITIALIZER and chooses a location
to call timer_setup() from before add_timer() or mod_timer() is called.
Adjusts callbacks to use from_timer() as needed.

s390: kernel: make lgr explicitly non-modular

2016-10-31T16:55:42+00:00

The Makefile currently controlling compilation of this code is obj-y
meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We replace module.h with init.h and export.h since the file does
export some symbols.

s390/sysinfo,stsi: change return code handling

2012-09-26T13:45:12+00:00

Change return code handling of the stsi() function:

In case function code 0 was specified the return value is the
current configuration level (already shifted). That way all
the code that actually copied the stsi_0() function can go
away.

Otherwise the return value is 0 (success) or negative to
indicate an error (currently only -EOPNOTSUPP).

Also stsi() is no longer an inline function. The function is
not performance critical, but every caller would generate an
exception table entry for this function.

s390/lgr: Add init check to lgr_info_log()

2012-07-20T09:15:01+00:00

If lgr has not been initialized, the lgr_info_log() function currently
crashes because 'lgr_page' is not allocated. To fix this 'lgr_page'
is allocated statically now.
