xtensa: don't limit csum_partial export by CONFIG_NET

2017-11-11T13:34:27+00:00

commit 7f81e55c737a8fa82c71f290945d729a4902f8d2 upstream.

csum_partial and csum_partial_copy_generic are defined unconditionally
and are available even when CONFIG_NET is disabled. They are used not
only by the network drivers, but also by scsi and media.
Don't limit these functions export by CONFIG_NET.

xtensa: don't use alternate signal stack on threads

2013-11-28T14:02:04+00:00

commit cba9a90053e3b7973eff4f1946f33032e98eeed5 upstream.

According to create_thread(3): "The new thread does not inherit the creating
thread's alternate signal stack". Since commit f9a3879a (Fix sigaltstack
corruption among cloned threads), current->sas_ss_size is set to 0 for cloned
processes sharing VM with their parent. Don't use the (nonexistent) alternate
signal stack in this case. This has been broken since commit 29c4dfd9 ([XTENSA]
Remove non-rt signal handling).

Fixes the SA_ONSTACK part of the nptl/tst-cancel20 test from uClibc.

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.

xtensa: Fixup irq conversion fallout and nmi_count

2011-04-19T22:32:09+00:00

Some unnamed moron fatfingered the arguments of the irq chip callbacks
to irq_chip instead of irq_data.

While at it remove the nmi_count() print in arch_show_interrupts()
which has been broken before the irq conversion already.
