[Qemu-devel] [PATCH v5 00/10] tcg: Direct block chaining clean-up

[Sergey Fedorov]

From: Sergey Fedorov <address@hidden>

This series combines a set of patches which is meant to improve overall code
structure and readability of the direct block chaining mechanism. The other
point is to make a step towards thread safety of TB chainig.

This series is based on commit: 1d02fa9e045b ("translate-all: Adjust 256mb
testing for mips64") from git://github.com/rth7680/qemu.git tcg-next and is
available at git://github.com/sergefdrv/qemu.git tb-chaining-cleanup-v5

Summary of changes:
 Changes in v5:
  * Fixed rebase conflicts
  * Don't check for in_superpage() in target-alpha/translate.c for
    user-mode [PATCH v5 10/10]
 Changes in v4:
  * Removed assert from tb_add_jump() [PATCH v4 02/10]
  * Added comment on TB stuff synchronization [PATCH v4 04/10]
  * Documented tcg_gen_goto_tb() and moved its usage notes there
    [PATCH v4 09/10] and [PATCH v4 10/10]
  * Cc'ed usermode maintainers in commit message [PATCH v4 10/10]
 Changes in v3:
  * New patch to clean up safety checks [PATCH v3 09/10]
  * New patch to eliminate unneeded checks in user-mode [PATCH v3 10/10]
 Changes in v2:
  * Eliminated duplicate dereference of 'ptb' in tb_jmp_remove() [PATCH v2 2/8]
  * Tweaked a comment [PATCH v2 4/8]
  * Complete rewrite [PATCH v2 5/8]
  * Tweaked a comment; eliminated duplicate dereference of 'ptb' in
    tb_jmp_unlink() [PATCH v2 8/8]
