powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

all: replace find_next{,_zero}_bit with find_first{,_zero}_bit where appropriate

2022-01-15T16:47:31Z

find_first{,_zero}_bit is a more effective analogue of 'next' version if start == 0. This patch replaces 'next' with 'first' where things look trivial. Signed-off-by: Yury Norov Tested-by: Wolfram Sang

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

powerpc/pasemi: Use dma_zalloc_coherent()

powerpc: don't use ioremap_prot() nor __ioremap() unless really needed.

2018-10-14T07:04:09Z

In many places, ioremap_prot() and __ioremap() can be replaced with higher level functions like ioremap(), ioremap_coherent(), ioremap_cache(), ioremap_wc() ... Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman

powerpc/pasemi: Use pr_err/pr_warn... for kernel messages

2018-08-07T14:32:31Z

Pasemi code still uses printk(KERN_ERR/KERN_WARN ... change these to pr_err(, pr_warn(... to match other powerpc arch code. No functional changes. Signed-off-by: Darren Stevens [mpe: Unsplit some strings while we're at it] Signed-off-by: Michael Ellerman

powerpc: Use pr_warn instead of pr_warning

2017-12-04T00:54:34Z

At some point, pr_warning will be removed so all logging messages use a consistent _warn style. Update arch/powerpc/ Miscellanea: o Coalesce formats o Realign arguments o Use %s, __func__ instead of embedded function names o Remove unnecessary line continuations Signed-off-by: Joe Perches Acked-by: Geoff Levand [mpe: Rebase due to some %pOF changes.] Signed-off-by: Michael Ellerman

powerpc: Delete non-required instances of include

2014-01-15T02:46:44Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. The one instance where we add an include for init.h covers off a case where that file was implicitly getting it from another header which itself didn't need it.

powerpc: various straight conversions from module.h --> export.h

2011-10-31T23:30:44Z

All these files were including module.h just for the basic EXPORT_SYMBOL infrastructure. We can shift them off to the export.h header which is a way smaller footprint and thus realize some compile time gains. Signed-off-by: Paul Gortmaker
