lm32: signal: Use restore_altstack()
do_sigaltstack() will be gone in the next upstream release, restore_altstack() is it's replacement. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: signal: Use flush_icache_range() instead of open-coding it.
Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: signal: Reset restart_block.fn in rt_sigreturn
This is required for proper operation. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

lm32: signals: Add proper __user annotation for setup_sigcontext()
The sigcontext struct we are working with here is on the userspace stack. Fixes the following sparse warnings: arch/lm32/kernel/signal.c:114:31: warning: incorrect type in argument 1 (different address spaces) arch/lm32/kernel/signal.c:114:31: expected void [noderef] <asn:1>*to arch/lm32/kernel/signal.c:114:31: got struct pt_regs *<noident> arch/lm32/kernel/signal.c:115:16: warning: incorrect type in initializer (different address spaces) arch/lm32/kernel/signal.c:115:16: expected unsigned long [noderef] <asn:1>*__pu_addr arch/lm32/kernel/signal.c:115:16: got unsigned long *<noident> arch/lm32/kernel/signal.c:148:34: warning: incorrect type in argument 1 (different address spaces) arch/lm32/kernel/signal.c:148:34: expected struct sigcontext *sc arch/lm32/kernel/signal.c:148:34: got struct sigcontext [noderef] <asn:1>*<noident> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

consolidate declarations of k_sigaction
Only alpha and sparc are unusual - they have ka_restorer in it. And nobody needs that exposed to userland. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

consolidate kernel-side struct sigaction declarations

On success get_signal_to_deliver() fills k_sigaction and siginfo. _All_ users pass it addresses of the local variables sitting in the same function. Then they proceed to pass those addresses pretty much in tandem to a bunch of helper functions; again, all callers of those helpers are passing them such a pair, and one that had been through get_signal_to_deliver() at that. The obvious cleanup: introduce a new type that would contain a <k_sigaction,siginfo> pair (struct ksignal) and begin switching to using it. Turns out that it's convenient to store the signal number in the same object. New helper, taking that sucker is a wrapper for get_signal_to_deliver(); takes struct ksignal * and returns bool. On success fills ksignal with the information for signal handler to be invoked. For now it's a macro (to avoid header ordering headache), but eventually it'll be a function in kernel/signal.c, with get_signal_to_deliver() folded into it.

new helper: signal_setup_done()
usual "call force_sigsegv or signal_delivered" logics. Takes ksignal instead of separate siginfo/k_sigaction. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

lm32: entry.S: Use PT_Rxx instead of magic numbers
Use the PT_Rxx defines instead of magic number for accessing the pt_regs fields. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: processor.h: More cleanups
Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
It is unused these days. There is a generic implementation of it now. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: timex.h: Remove CLOCK_TICK_RATE
It's unused. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: prom.h: Remove #ifdef CONFIG_OF
CONFIG_OF is always defined for lm32. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
We never use it. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
-
lm32: process.c: Include linux/pm.h
Fixes the following sparse warning: arch/lm32/kernel/process.c:53:6: warning: symbol 'pm_power_off' was not declared. Should it be static? Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
