In arch/powerpc/include/asm/bitops.h, the comments about bit numbers in
large (> 1 word) bitmaps have two typos:
- On ppc64 system, the LSB of the 4th word should be bit 192 rather than
196, because if it's bit 196, bit 192-195 will be missing in the
bitmap.
- On ppc32 system, the LSB of the se
The function tm_reclaim_task is only called from the function
__switch_to_tm. This patch merges these two functions to make
it more readable without changing the functionality in any way.

This patch adds one more test case called tm-ptrace targeting TM
related ptrace interfaces. This test creates one child process to
run some basic transactions and the parent process attaches the
child to do some ptrace probing using the recently added regset
interfaces. The parent process then comp
This patch enables get and set of miscellaneous debug registers through
ptrace PTRACE_GETREGSET-PTRACE_SETREGSET interface by implementing new
powerpc specific register set REGSET_MISC support corresponding to the
new ELF core note NT_PPC_MISC added previously in this regard.

This patch enables get and set of transactional memory related register

This patch enables the vr_get which gets the running value of all
the VMX registers and the vr_set which sets the running value of
of all the VMX registers to accommodate in transaction ptrace

This patch adds four new core note sections for PowerPC transactional
memory and one core note section for general miscellaneous debug registers.
These addition of new elf core note sections extends the existing elf ABI
without affecting it in any manner.

This patch creates a new function called flush_tm_state to flush
the existing transactional memory state from the thread. It also
creates a function called flush_tmregs_to_thread which will then
be used on subsequent patches in this series.

This patch series adds five new ELF core note sections which can be
used with existing ptrace request PTRACE_GETREGSET-SETREGSET for accessing
various transactional memory and miscellaneous debug register sets on PowerPC

We have some code in udbg_uart_getc_poll that tries to protect
against a NULL udbg_uart_in, but gets it all wrong.
Found with the LLVM static analyzer (scan-build).
Fixes: 309257484cc1 ("powerpc: Cleanup udbg_16550 and add support for LPC
PIO-only UARTs")

Hi Ben, Mikey,
Can you please take a look at this patch? I feel the commit dcb1869 was
just a plug-in solution. Shouldn't we take a look at this again?
Ideally we should not need this check. With the cpuidle redesign on
PowerNV going in, we can enable fastsleep at bootup itself and without
check
