* Blackfin: dpmc: omit RETE/RETN when hibernatingMike Frysinger2011-07-231-4/+0
| | | | | | | | The RETE/RETN registers are only used in emulation(JTAG) and NMI nodes, or as scratch registers, neither of which need to be saved/restored as this code doesn't execute at those core event levels. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: dpmc: optimize SIC_IWR programming a littleMike Frysinger2011-07-231-9/+6
| | | | | | | For parts with more than one SIC_IWR, we can optimize the writing a little bit using better Blackfin insns. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gpio/ints: generalize pint logicMike Frysinger2011-07-233-12/+19
| | | | | | | | Have the logic that uses peripheral interrupt blocks key off of pint defines rather than CPU names so that things are generalized across families. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: dpmc: bind to MMR names and not CPUsMike Frysinger2011-07-231-4/+3
| | | | | | | Have the code work off of MMR names rather than CPU defines so there is less code to tweak in the future with new parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: debug-mmrs: generalize pint logicMike Frysinger2011-07-231-19/+31

* Blackfin: bf54x: switch to common pint MMR structMike Frysinger2011-07-231-18/+5
| | | | | | | We have a struct in the headers describing the register layout, so drop the local duplicate one. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf54x: tweak MMR pint namesMike Frysinger2011-07-232-2/+2
| | | | | | | The hardware block uses the name "request" rather than "irq", so update the struct accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf54x: constify pint register arrayMike Frysinger2011-07-231-1/+1
| | | | | | The array of pointers to register blocks never changes, so constify it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gpio: punt unused GPIO_# definesMike Frysinger2011-07-232-52/+3
| | | | | | | | These defines don't accomplish much as GPIO_# is the same thing as #. Each CPU already provides helpful symbolic defines like GPIO_<PIN> which everyone uses, so just punt these # ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: convert unicode space gremlinsMike Frysinger2011-07-237-27/+27
| | | | | | | | Not sure how these guys slipped in, but they're annoying me. So bring these unicode space gremlins down to earth to normal ascii spaces. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: pwm: implement linux/pwm.h APIMike Frysinger2011-07-233-0/+111

* Blackfin: gptimers: add enable/disable by timer idMike Frysinger2011-07-231-0/+10
| | | | | | | The API is geared around timer ids, except for the act of enabling and disabling timers. So add a small helper to fill out the gap. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: make sure percpu section is aligned in XIP buildsSteven Miao2011-07-231-0/+1
| | | | | | | | The alignment is normally handled by PERCPU(), but we need to do it ourselves in the XIP build due to the custom layout. Signed-off-by: Steven Miao <realmz6@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gptimers: use bfin read/write helpersMike Frysinger2011-07-231-20/+25

* Blackfin: gptimers: use register structs from common headerMike Frysinger2011-07-231-32/+16
| | | | | | | Now that asm/gptimers.h has the hardware register struct layout, there's no need to duplicate things locally. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: debug-mmrs: disable PERIPHERAL_MAP for IMDMA channelsMike Frysinger2011-07-231-1/+2
| | | | | | | | The documentation for the IMDMA channels appears to be incorrect. These DMA blocks don't actually have PERIPHERAL_MAP MMRs for us to access. Attempts to do so lead to system mmr hardware errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: convert to asm-generic/mutex-dec.h for all systemsMike Frysinger2011-07-231-76/+1
| | | | | | | The Blackfin mutex.h is merely a copy of an older asm-generic/mutex-dec.h, so punt it and just use the common one directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: optimize double fault boot checkingMike Frysinger2011-07-236-63/+62
| | | | | | | | This moves the double fault data used at boot time into a single struct which can then easily be addressed with indexed loads rather than having to explicitly load multiple addresses. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: boards: clean up redundant/dead spi resourcesMike Frysinger2011-07-2326-896/+0
| | | | | | | | | | | | The default for the Blackfin SPI driver is 8 bits and dma disabled, so many of the bfin5xx_spi_chip resources are redundant. So punt those parts. Further, drivers should themselves be declaring 16 bit transfers, so for those that do, and for the ones which no longer do 16 bit transfers, drop the bfin5xx_spi_chip resources.

| * x86-64: Emulate legacy vsyscallsAndy Lutomirski2011-06-078-140/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a fair amount of code in the vsyscall page. It contains a syscall instruction (in the gettimeofday fallback) and who knows what will happen if an exploit jumps into the middle of some other code. Reduce the risk by replacing the vsyscalls with short magic incantations that cause the kernel to emulate the real vsyscalls. These incantations are useless if entered in the middle. This causes vsyscalls to be a little more expensive than real syscalls. Fortunately sensible programs don't use them. The only exception is time() which is still called by glibc through the vsyscall - but calling time() millions of times per second is not sensible. glibc has this fixed in the development tree. This patch is not perfect: the vread_tsc and vread_hpet functions are still at a fixed address. Fixing that might involve making alternative patching work in the vDSO.
