2010-10-27MN10300: Cacheflush functions should take unsigned long addressesAkira Takeuchi2-15/+15
The functions that perform cache flushing should take addresses of unsigned long type, not unsigned int. Signed-off-by: Akira Takeuchi <takeuchi.akr@jp.panasonic.com> Signed-off-by: Kiyoshi Owada <owada.kiyoshi@jp.panasonic.com> Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: AM34: The current cacheflush routines operate by controlling tag regsDavid Howells4-2/+23
The current cache flush and invalidate routines operate by controlling the cache tag registers. Rename the files and add config items to select them. This makes it easier to support the use of other cache flush methods instead, such as the use of AM34's area purge registers, if available. Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: Reorder asm/cacheflush.h to put primitives firstDavid Howells1-44/+44
Reorder asm/cacheflush.h to put arch primitives first, before the main functions so that the main functions can be inline asm rather than #defines when non-trivial. Signed-off-by: David Howells <dhowells@redhat.com>

2010-10-27MN10300: Provide the functions to fully disable maskable interruptsAkira Takeuchi1-0/+77
The local_irq_disable() function and co. merely raise the interrupt mask on the MN10300 arch to exclude normal interrupts. This still lets other, higher priority maskable interrupts through, such as are used to service gdbstub's serial port and the MN10300 on-chip serial port virtual FIFOs. Provide functions to allow the maskable interrupts to be fully disabled, which will exclude those interrupts.

2010-10-27MN10300: Prevent cnt32_to_63() from being preempted in sched_clock()David Howells1-0/+5
Prevent cnt32_to_63() from being preempted in sched_clock() because it may read its internal counter, get preempted, get delayed for more than the half period of the 'TSC' and then write the internal counter, thus corrupting it. Whilst some callers of sched_clock() have interrupts disabled or hold spinlocks, not all do, and so preemption must be held here. Note that sched_clock() is called from lockdep, but that shouldn't be a problem because although preempt_disable() calls into lockdep, lockdep has a recursion counter to deal with this.

2010-10-26checkpatch: check for incorrect permissionsRabin Vincent1-1/+13
Throw an error when a source file has been given execute permissions using the mode change line present in git diffs. Also alow the filename matching to use the "diff" line in addition to the "+++" line, since the mode change lines appear before any "+++" lines.

2010-10-26checkpatch: ensure kconfig help checks only apply when we are adding helpAndy Whitcroft1-5/+21
When checking the length of the help we need to be sure we are seeing the whole story before erroring. Firstly we only want to check when adding the help in the first place. Second we need to be sure that we are seeing the end of the entry, nominally when there is no context below or that context shows the start of the next entry.

2010-10-26checkpatch: simplify and consolidate "missing space after" checksAndy Whitcroft1-10/+5
Commonise the code for missing spaces after struct, union, and enum such that they share the same code. Ensure we cover all the common cases in each case. Check against the sanitised line to ensure we do not report on comments and strings.

2010-10-26checkpatch: add check for space after struct, union, and enumAndy Whitcroft1-0/+10
Add spacing checks for struct, union, and enum definitions. Check the spacing after type and before the equals (=) and open brace ({). Based on a patch by Joe Perches.

2010-10-26checkpatch: returning errno typically should be negativeAndy Whitcroft1-0/+7
Add a (strict mode only) test to check for non-negative returns of what appear to be errno values as the majority case these should indeed be negative.

2010-10-26checkpatch: handle casts better fixing false categorisation of : as binaryAndy Whitcroft1-0/+5
The following incantation is triggering categorisation of its colon (:) as a binary form, which it is not: return foo ? (s8)bar : baz; Handle casts differently from types in the categoriser, allowing us to better track (s8)bar as a value and not a declaration.
