2009-09-17MIPS: TXx9: Fix error handling.Julia Lawall
Error handling code following a kzalloc should free the allocated data. Error handling code following an ioremap should iounmap the allocated data. The semantic match that finds the first problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,f1,l; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } ( x->f1 = E | (x->f1 == NULL || ...) | f(...,x->f1,...) ) ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: TXx9: Disable PM capability of TX493[89] internal etherAtsushi Nemoto

2009-09-17MIPS: make page.h constants available to assembly.Nelson Elhage
page.h includes ifndef __ASSEMBLY__ guards, but PAGE_SIZE and some other constants are defined using "1UL", which the assembler does not support.

2009-09-17MIPS: Alchemy: add gpio_request/gpio_free stubs for CONFIG_GPIOLIB=nManuel Lauss
Some drivers use gpio_request/gpio_free regardless of whether gpiolib is actually built; add stubs to work around the ensuing compile failures. Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Tested-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Lasat: Fix compilationAlexey Dobriyan
Header needed for current_cpu_data which expands to smp_processor_id(). However, linux/smp.h can't be included into asm/cpu-info.h due to horrible circular dependencies, so plug it here. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Octeon: Check all CCAs in cvmx_write_csr.David Daney
The current code only checks CCA of 0 when deciding if a dummy read is needed. Since the kernel can (and does) use other CCAs we need to mask out the CCA bits from the address. Since the address constant now fits in 16 bits, there is an added benefit that smaller code is generated.

2009-09-16Blackfin: update ftrace for latest toolchainYi Li
The mcount support that was finally added to the Blackfin gcc port isn't exactly the same as what ftrace was developed against. Now that the final gcc version is in place, update the ftrace code to match. While updating this, fix the swapped arguments to the tracer (signature is (ip, parent_ip) while we were passing (parent_ip, ip)).

2009-09-16Blackfin: fix elf_fpregset_t definitionMike Frysinger
The elf_fpregset_t type relied on an empty struct in the asm/user.h, but the transition to asm-generic/user.h dropped that empty struct. Rather than restore this useless struct, define the only user (elf_fpregset_t) as an empty struct itself. This fixes building when ELF dump support is enabled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: unify cache init functionsMike Frysinger
The CPLB implementations (mpu/nompu) had exact copies of the cacheinit code. Even the i/d cache functions are largely the same. So unify them both in the common kernel cache code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: increase default async timings for parallel flashesSonic Zhang
The default async timings are a little too fast for the parallel flash that is attached by default to the async banks. So slow things down a bit so accessing the hardware is stable. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: use raw_smp_processor_id() in exception codeYi Li
When preempt debugging is enabled, smp_processor_id() may utilize the "current" structure. This may not be safe to access under all exceptions due to it being in dynamically allocated memory. So in exception code, make sure we use raw_smp_processor_id() instead to get at the real value directly. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: Fix link errors with binutils 2.19 and GCC 4.3Ingo Molnar
Not sure whether this has been reported/fixed before. Today I built a Blackfin tool-chain from scratch for -tip testing, and it triggers: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.data_a_l1' referenced in expression and: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.text_data_l1' referenced in expression Now i dont have any way to test this linker script, but it now at least builds fine after fixing what appears to be typos in those assert statements.

2009-09-16Blackfin: optimize fixed code handling for the most common caseMike Frysinger
The majority of the time we are returning to user space, it is not in the fixed atomic code region. So rather than branch to a function where we check the PC and return, do the check inline and branch only when needed. Also, tweak some of the fixed code handling based on assumptions we are aware of but cannot be expressed in C. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: delete '-spi' suffix in ad1836/ad1938 driver nameBarry Song

2009-09-16Blackfin: cleanup sync handling when enabling/disabling cplbsYi Li
The handling of updating the [DI]MEM_CONTROL MMRs does not follow proper sync procedures as laid out in the Blackfin programming manual. So rather than audit/fix every call location, create helper functions that do the right things in order to safely update these MMRs. Then convert all call sites to use these new helper functions. While we're fixing the code, drop the workaround for anomaly 05000125 as that anomaly applies to old versions of silicon that we do not support.

2009-09-16Blackfin: bf537-stamp: drop ATA interrupt probe workaroundBarry Song
The interrupt probe workaround doesn't work without hacks to common code, and the add-on card only needs a simple resistor to fix the problem, so drop the board-specific hack. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: improve double fault debug handlingGraf Yang
Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
