That would seem to at least make all the filesystem code happier, and they

This patch series introduces little-endian bit operations in asm/bitops.h
for all architectures and converts all ext2 non-atomic and minix bit
operations to use little-endian bit operations.  It enables us to remove
ext2 non-atomic and minix bit operations from asm/bitops.h.  The reason
they should be removed from asm/bitops.h is as follows:

For ext2 non-atomic bit operations, they are used for little-endian byte
order bitmap access by some filesystems and modules.  But using ext2_*()
functions on a module other than ext2 filesystem makes some feel strange.

For minix bit operations, they are only used by minix filesystem and are
useless by other modules.  Because byte order of inode and block bitmap is

This patch:

In order to make the forthcoming changes smaller, this merges macro
definisions in asm-generic/bitops/le.h for big-endian and little-endian as
much as possible.

This also removes unused BITOP_WORD macro.

asm-generic/bitops/le.h is only intended to be included directly from

which implements generic ext2 or minix bit operations.

This stops including asm-generic/bitops/le.h directly and use ext2

It seems odd to use ext2_*_bit() on rds, but it will replaced with
__{set,clear,test}_bit_le() after introducing little endian bit operations
for all architectures.  This indirect step is necessary to maintain
bisectability for some architectures which have their own little-endian

This reverts commit a7a75c8f.

There are two different variations on how Intel hardware addresses the
"Hardware Status Page". One as a location in physical memory and the
other as an offset into the virtual memory of the GPU, used in more
recent chipsets. (The HWS itself is a cacheable region of memory which
the GPU can write to without requiring CPU synchronisation, used for
updating various details of hardware state, such as the position of
the GPU head in the ringbuffer, the last breadcrumb seqno, etc).

These two types of addresses were updated in different locations of code
- one inline with the ringbuffer initialisation, and the other during
device initialisation. (The HWS page is logically associated with
the rings, and there is one HWS page per ring.) During resume, only the
ringbuffers were being re-initialised along with the virtual HWS page,
leaving the older physical address HWS untouched. This then caused a
hang on the older gen3/4 (915GM, 945GM, 965GM) the first time we tried
to synchronise the GPU as the breadcrumbs were never being updated.

A conflict between 52c50567 ("mm: swap: unlock swapfile inode mutex
before closing file on bad swapfiles") and 83ef99be ("sys_swapon:
remove did_down variable") caused a double unlock of the inode mutex
(once in bad_swap: before the filp_close, once at the end just before
returning).

The patch which added the extra unlock cleared did_down to avoid
unlocking twice, but the other patch removed the did_down variable.

To fix, set inode to NULL after the first unlock, since it will be used
after that point only for the final unlock.

While checking this patch, I found a path which could unlock without
locking, in case the same inode was added as a swapfile twice. To fix,
move the setting of the inode variable further down, to just before
claim_swapfile, which will lock the inode before doing anything else.

Instead of always creating a huge (268K) deflate_workspace with the
maximum compression parameters (windowBits=15, memLevel=8), allow the
caller to obtain a smaller workspace by specifying smaller parameter
values.

For example, when capturing oops and panic reports to a medium with
limited capacity, such as NVRAM, compression may be the only way to
capture the whole report.  In this case, a small workspace (24K works
fine) is a win, whether you allocate the workspace when you need it (i.e.,
during an oops or panic) or at boot time.

I've verified that this patch works with all accepted values of windowBits
(positive and negative), memLevel, and compression level.

d_alloc_name return NULL in case error, but we expect errno in
devpts_pty_new.

The test program below will hang because io_getevents() uses
add_wait_queue_exclusive(), which means the wake_up() in io_destroy() only
wakes up one of the threads.  Fix this by using wake_up_all() in the aio
code paths where we want to make sure no one gets stuck.

	// t.c -- compile with gcc -lpthread -laio t.c

	#include <libaio.h>
	#include <pthread.h>
	#include <stdio.h>
	#include <unistd.h>

	static const int nthr = 2;

	void *getev(void *ctx)
	{
		struct io_event ev;
		io_getevents(ctx, 1, 1, &ev, NULL);
		printf("io_getevents returned\n");
		return NULL;
	}

	int main(int argc, char *argv[])
	{
		io_context_t ctx = 0;
		pthread_t thread[nthr];
		int i;

		io_setup(1024, &ctx);

		for (i = 0; i < nthr; ++i)
			pthread_create(&thread[i], NULL, getev, ctx);

		sleep(1);

		io_destroy(ctx);

		for (i = 0; i < nthr; ++i)
			pthread_join(thread[i], NULL);

		return 0;
	}

Remove code enabled only when CONFIG_PREEMPT_RT is turned on because it is
not used in the vanilla kernel.
