In the recent commit to add an explicit ratelimit state when showing
unhandled signals, commit 35a52a10c3ac ("powerpc/traps: Use an
explicit ratelimit state for show_signal_msg()"), I put the check of
show_unhandled_signals and the ratelimit state before the call to
unhandled_signal() so as to avoi
When hot-removing memory release_mem_region_adjustable() splits iomem
resources if they are not the exact size of the memory being
hot-deleted. Adding this memory back to the kernel adds a new resource.
Eg a node has memory 0x0 - 0xf. Hot-removing 1GB from
0xf4000 results in the single
Hi Linus,
Please pull powerpc updates for 4.19.
There's a trivial conflict in Documentation/admin-guide/kernel-parameters.txt
between our addition of nospectre_v1 and the x86 documentation for nosmt.
There's another in arch/m68k/mac/misc.c, which was coordinated with
Geert but unfortunately we s

The generic code is race when multiple children of a PCI bridge try to
enable it simultaneously.
This leads to drivers trying to access a device through a not-yet-enabled
bridge, and this EEH errors under various circumstances when using parallel
driver probing.
There is work going on to fix that

Currently msr_tm_active() is a wrapper around MSR_TM_ACTIVE() if
CONFIG_PPC_TRANSACTIONAL_MEM is set, or it is just a function that
returns false if CONFIG_PPC_TRANSACTIONAL_MEM is not set.
This function is not necessary, since MSR_TM_ACTIVE() just do the same and
could be used, removing the duali

After upgrading my distro compiler to gcc-8.2, Linux fails to compile on
32-bit powerpc (tested with 4.17, 4.18 and v4.18-7873-gf91e654474d4).
