2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov1-0/+1
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.

2009-06-27score: clean up mm/init.cArnd Bergmann1-24/+10
score does not need multiple zero pages, because it does not suffer from cache aliasing problems, so simplify that code. Also make some functions static and include the appropriate header files. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: make irq.h definitions localArnd Bergmann2-20/+23
Some internal definitions of the interrupt controller are only needed in irq.c, so move them out of the global irq.h header. Also add proper __iomem annotations for sparse. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: cleanups: dead code, 0 as pointer, shadowed variablesArnd Bergmann3-20/+8
A few smaller issues found by sparse, some code that was never used, two instances of '0' instead of 'NULL' and local variables shadowing another one. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: fix function prototypesArnd Bergmann3-12/+17
Syscalls should return 'long' and be marked as 'asmlinkage'. Functions that are only used in a single file should be 'static'. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: add address space annotationsArnd Bergmann4-14/+16
Annotate the address space for pointers that are used correctly with __user and __iomem, so that sparse can better warn about incorrect casts. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: add missing #includesArnd Bergmann5-1/+10
Files that define a global function should #include the header with its declaration to make sure that the prototypes do not diverge. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2009-06-19score: add prototypes for wrapped syscallsArnd Bergmann1-2/+4
Every system call should be declared, so this adds missing declarations for the ones we were missing so far. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: remove init_mmArnd Bergmann1-2/+0
init_mm is now part of the common code and not provided by the architecture any more. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: add generic sys_call_tableArnd Bergmann4-53/+18
This adds back a sys_call_table to the score architecture, which got lost in the conversion to the generic unistd.h file. It's rather worrying that the code got submitted without a system call table, which evidently means that it got zero testing. Since the system call table has a different layout from the old one (which was modeled after the mips-o32 one), I also try to fix the entry.S path to use it. In the modified calling conventions, all system call arguments are passed as registers r4 through r9, instead of r4 through r7 plus stack for the fifth and sixth argument. This matches what other architectures to when they normally pass arguments on the stack. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: remove __{put,get}_user_unknownArnd Bergmann1-12/+0
The point of these extern declarations is to provoke a link error, so an architecture must not provide a symbol for them. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: unset __ARCH_WANT_IPC_PARSE_VERSIONArnd Bergmann1-1/+0
This really should not be needed. The change for not changing the IPC code for every new architecture just went into 2.6.31, so we can skip it now. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
