* alpha: Remove usage of the deprecated "pci-dma-compat.h" APIChristophe JAILLET2022-02-251-3/+4
| | | | | | | | | | | | | | | | | | | In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. A coccinelle script has been used to perform the needed transformation. It can be found in [3].

* floppy: split the base port from the register in I/O accessesWilly Tarreau2020-05-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we have architecture-specific fd_inb() and fd_outb() functions or macros, taking just a port which is in fact made of a base address and a register. The base address is FDC-specific and derived from the local or global "fdc" variable through the FD_IOPORT macro used in the base address calculation. This change splits this by explicitly passing the FDC's base address and the register separately to fd_outb() and fd_inb(). It affects the following archs: - x86, alpha, mips, powerpc, parisc, arm, m68k: simple remap of port -> base+reg - sparc32: use of reg only, since the base address was already masked out and the FDC controller is known from a static struct. - sparc64: like x86 for PCI, like sparc32 for 82077 Some archs use inline functions and others macros. This was not unified in order to minimize the number of changes to review. For the same reason checkpatch still spews a few warnings about things that were already there before. The parisc still uses hard-coded register values and could be cleaned up by taking the register definitions. The sparc per-controller inb/outb functions could further be refined to explicitly take an FDC register instead of a port in argument but it was not needed yet and may be cleaned later.

* treewide: fix potentially dangerous trailing ';' in #defined values/expressionsPhil Carmody2011-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.)

* alpha: move include/asm-alpha to arch/alpha/include/asmLinus Torvalds2008-08-151-0/+115
Sam Ravnborg did the build-test that the direct header file move works, I'm just committing it. This is a pure move: mkdir arch/alpha/include git mv include/asm-alpha arch/alpha/include/asm with no other changes.
