The jump to 4f will cause the NUL padding loop to run at least one time, so if string length is zero just jump to the end. Otherwise we wrongly write one NUL byte when size==0. Signed-off-by: NSteven Miao <realmz6@gmail.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The documentation is a little iffy as to whether these are actual MMRs, but reading them on the hardware works, and the previous version of this logic (the SDH) had PID[4567]. So add it for RSI too. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Looks like the copying of MMR defines from the SDH block missed updating the addresses of the RSI_PID# registers. So tweak them to reflect the actual hardware. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The bf52x/bf54x have the incorrect addresses for USB_EP_NI7_RXINTERVAL and USB_EP_NI7_TXCOUNT, so adjust those. Further, the bf54x header puts the USB defines in the wrong place, so shuffle them back to the right grouping. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. > arch/blackfin/include/asm/unistd.h | 3 ++- > arch/blackfin/mach-common/entry.S | 1 + Acked-by: NMike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

The Blackfin arch, like the x86 arch, needs to adjust the PC manually after a breakpoint is hit as normally this is handled by the remote gdb. However, rather than starting another arch ifdef mess, create a common GDB_ADJUSTS_BREAK_OFFSET define for any arch to opt-in via their kgdb.h.

Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording.

The BF537 SIC combines the gpio port H mask A interrupts with the emac rx interrupt, so we need to demux this in software.

The search logic in the gpio demux walks all possible gpio blocks starting at the specified pin. The trouble on bf537 parts when we demux the port F and port G mask A interrupts is that we also demux port H mask A ints. Most of the time this isn't an issue as people don't usually use port H, but might as well avoid it when possible. Signed-off-by: NMike Frysinger <vapier@gentoo.org>
